Karl Robatsch

     Robatsch (October 14, 1929) was a leading Austrian player and a noted botanist. He moved to Graz at the age of 17 to become a student and often frequented the Mountainside CafĂ© and joined a local club 'SK Gemeinde' (Municipal chess club) where he quickly advanced to master.
     Becoming an International Master (IM) in 1957 and a Grandmaster in 1961, Robatsch dedicated much of his life to serving Austrian chess, representing the nation at eleven Chess Olympiads and one European Team Chess Championship. Up until his last Olympiad in 1994, he played first board on every occasion and returned some impressive results. At the 1960 Leipzig Olympiad, he astounded the chess world by scoring 84.4 per cent and taking the board 1 gold medal, while still only an IM. This was also the year that he became Austrian champion.
     While Robatsch played competitively over five decades, the high points of his international tournament career mostly occurred in the late 1950s and early 1960s. He continued to play to a high standard into the late 1990s.
     Robatsch displayed a highly combinative playing style in his younger days but like so many others, he adopted a more positional approach later in life. In his opening play he often played experimental moves and this led to some lively and historically important games. The system of opening moves commencing with 1. e4 g6 2. d4 Bg7 became a defense that Robatsch often played with the black pieces.
     His development as a player was hindered by an interest outside chess: botany. He became a highly esteemed orchidologist and was awarded the title of 'Professor' for his outstanding research work in the classification of different species and sub-species of orchid. He specialized in the study of a taxonomically complex genus of orchids called Epictatis and made significant contributions to the study of this group of orchids even in the final years of his life.
     Below is a photo of Robatsch with his registered Cypripedium hybrids (acaule x reninae) It is characterized by lush growth and a very attractive flower.

Robatsch died in 2000, following a long fight with throat and stomach cancer.
     In the following exciting game Tahl had to sacrifice his Q to blunt Robatsch’s attack. Robatsch still had the advantage, but couldn’t quite squeeze out the win.

A Chimp Named Ham plus a Nice Win by Robatsch

Ham
     Strange weather yesterday (Monday). Sunday was hot and humid with a cold front forecast to move through in the evening...all the ingredients for severe weather including tornadoes. Fortunately when the front came through (as evidenced by several minutes of strong wind) there were only some light sprinkles. 
     Monday saw some widely scattered pockets of rain with a few rumbles of thunder. At about 2:00pm it got pretty dark and I thought I heard rain and looked out the front window and saw nothing. Still thinking I heard rain, I looked out the back window and there was a drenching downpour and the patio and picnic table had rain bouncing off of them. I guess the rain has to stop somewhere and at that time it was right over our house. 
     Who remembers 1961? A chimpanzee named Ham was launched on a test flight into space in on January 31, 1961. Born in Cameroon in approximately 1957; he was captured and brought to a facility in Florida. In July 1959, he was transferred to Holloman Air Force Base in Alamogordo, New Mexico, to be trained for space flight as part of Project Mercury. His name was the acronym for Holloman Aero Medical.
     Ham, along with his partners, including another chimp named Enos (who would become the first and only chimpanzee to orbit the Earth), were trained by spending long periods of time confined in a chair and being trained to operate levers in response to light cues. 
     After 18 months of training, Ham was selected as the chimp whose life would be risked to test the safety of space flight on his body. 
     On January 31, 1961, at Cape Canaveral, Florida, Ham was blasted into space, strapped into a container called a couch. During a flight of about 16.5 minutes when he traveled at a speed of about 580 miles per hour to an altitude of 157 miles above the earth, he experienced about 6.5 minutes of weightlessness. Despite the g-forces and weightlessness, Ham performed his tasks correctly. 
     After he splashed down 130 miles off target his capsule began taking on water. It took several hours for a recovery ship to reach him and miraculously he was alive and appeared relatively calm. However, chimp experts interpreted his facial expression as being one of extreme fear and anxiety. Later when photographers wanted a picture of him in his “couch” he refused to get back into it and even several men could not force him to do so. 
     After his ordeal he was transferred to The National Zoo in 1963, where he was forced to lived alone for 17 years before being transferred to the North Carolina Zoo where he was allowed to live with other chimps. He died 22 years after his historic flight on January 18, 1983, at the estimated age of 26. On to the chess stuff... 
     Chess players who were lost in 1961 were Soviet GM Grigory Levenfish (1889-1961) who died in Moscow at the age of 71. Akiba Rubinstein (1880-1961) died in Antwerp, Belgium at the age of 80 and the 1923-24 champion of Scotland, Christopher Heath (1877-1961) who died in London at the age of 83. 
     Mikhail Botvinnk defeated Mikhail Tal to regain the world championship. Bobby Fischer won the US Championship for the 4th time. Boris Spassky won the Soviet Championship. 
     In December, 1961, US lady champ, Lisa Lane generated a lot of excitement when she was playing in the Hastings Reserve tournament. After she played four games in which she scored one draw, two losses and had one adjourned game, she withdrew claiming she was homesick and in love. 
     Like most of the people and events mentioned here, Austrian Grandmaster and noted botanist Karl Robatsch (October 14, 1929 - September 19, 2000) have been forgotten. 
    At the age of 17 he moved to Graz to become a student and while there he often frequented the local chess club where he quickly advanced to Master. He was awarded the IM title in 1957 and the GM title in 1961. 
     Robatsch played competitively for over fifty years with his greatest successes coming in the late 1950s and early 1960s. In his early years Robatsch was noted for his highly tactical play, but later he adopted a more positional approach. His opening play was often experimental and a system of opening moves commencing 1. e4 g6 2. d4 Bg7 was named after him. 
     Robatsch had a notable career in botany in which he was an highly esteemed orchidologist in which he performed outstanding research work in the classification of different species and sub-species of orchids. 
     He died in 2000, following a long fight with throat and stomach cancer. 
 

     His opponent was Vasja Pirc (December 19, 1907 – June 2, 1980), a Slovenian player best known as a strong exponent of the hypermodern defense now generally known as the Pirc Defence. Pirc was Yugoslav champion five times: 1935, 1936, 1937, 1951, and 1953. He was awarded the IM title in 1950 and the GM title in 1953. He was also an International Arbiter. He died in Ljubljana in 1980. A game that I liked (Fritz 17)

Modern Defense

     I recently saw a forum discussion where a player was advocating playing the Modern Defense because it's a universal defense that black can play against whatever move white opens with. The writer said the advantage of Modern is you don't need to study and learn many opening lines. While it may be true that you can play it against any white opening move, the idea that you don't need to learn any theory is mistaken. Maybe not as much as in the Najdorf Sicilian, but you have to learn some theory nevertheless. 
     I'm not exactly sure what the Modern Defense is. I think it's what we used to call the Robatsch Defense named after Karl Robatsch (October 14, 1929–September 19, 2000), a leading Austrian player and a noted botanist. What about the Pirc, named after Vasja Pirc (December 19, 1907–June 2, 1980) a leading Yugoslav (Slovenian) player? 
     ECO classifies the Modern Defense as B06 and codes B07 to B09 are assigned to the Pirc. My Modern Chess Openings, 10th edition, groups them together and calls it the Pirc–Robatsch Defense. As I understand it, the main difference between the Modern and the Pirc is that in the Modern, Black delays developing his knight to f6 which gives white the opportunity of playing c2-c3 which is supposed to limit the effectiveness of black's B on g7.
     Transposition possibilities abound with either defense. After 1.e4 g6 2.d4 Bg7, in addition to being a Modern or Pirc, it can morph into a King's Indian, Dragon Sicilian or something else which means black simply can't apply the same strategy in all situations. Also, after 1.e4 g6 white can, besides 2.d4, play 2.Nf3, 2.Nc3, 2.c4 or just about anything reasonable move.
     Another example is the King's Indian Attack. One site says the advantage of playing this is that it can be set up unhindered and it can lead to excellent attacking chances on the K-side. So can a whole bunch of other openings. I've been down this playing systems road. Way, way back it was the Stonewall Attack, then years later it was the KIA. I bought a book on it and the first thing the author said was white's strategy will be dictated by black's setup and there were chapters on how to correctly play against black formations like the K-Indian, Q-Indian, French, Sicilian, etc. Then there was the Torre Attack, another good 'system.' Guess how the book was arranged? There were chapters on how white needs to play against a wide variety of black formations. The KIA and Torre are decent openings, but they still required a lot of study and memorization in order to play them correctly. The same could be said of the Colle. 
     Back to the Modern...what if white plays 1. e4 g6 2. d4 Bg7 and now, instead of 2.Nc3 or 2.Nf3, he plays 3. c4. Isn't the game headed for a K-Indian with all its different options for both sides? Even though 1...g6 is universal, it seems like there is a lot of theory to be studied because black can't just willy-nilly play the same moves against anything white plays. 
     Even if white cooperates and plays, say, 1. e4 g6 2. d4 Bg7 3. Nc3 d6 4. Nf3 Nf6 5. Be2 O-O 6. O-O, arriving at this position:


     According to my Rybka2 opening book black has 12 responses, the most popular being 6...c6 followed by 6...Bg4 and 6...c5. All three lead to a different type of position that will require different handling by both sides. Let's say black chooses the most popular 6...c6. The Rybka2 book lists 7 reasonable replies by white and, again, black's strategy will depend on which move white chooses. All this shoots down the idea that by playing the Modern, or any opening 'system,' you can avoid learning variations and a lot of theory. At least if you want to play correctly. 
     The following game by by a couple of class players demonstrates the point. Instead of transposing into the Old Indian Defense, black continues with a mishmash of moves seen in different defensive setups and soon gets into trouble.

Miniature by Walter Browne

      I came across this miniature the other day and was just as intrigued by it as I was when I first saw it.
Miquel Quinteros

      Browne’s opponent, Miquel Quinteros (December 28, 1947 in Buenos Aires) is an Argentine GM who won the championship of Argentina at the age of 18 and in 1969 took eighth place at the Mar del Plata Zonal. In 1972, he tied for second/third place at the SĂŁo Paulo Zonal which earned him a place at the Interzonal in Leningrad the following year where he finished 11th-12th. In 1975 he also qualified for the Manila Zonal in 1976 where he only managed 14th. Quinteros had several high place finishes in other events though and played six times on the Argentine Olympic team. In 1987, he was barred from playing in FIDE events for three years because he played in South Africa, a FIDE-sanctioned country. Quinteros was the first GM to visit South Africa since 1981 and he gave simultaneous exhibitions several cities.
      In 1988 the FIDE Congress was in Thessaloniki where they conducted their grimy political business. You know, the show trials, kangaroo courts, bribes, back room deals etc. The big question was, would Quinteros, who by the way was an old friend of Bobby Fischer and who had been one of the most active players in the world, actually be stripped of the grandmaster title and banned from playing chess for the rest of his life?
      Sidebar: Other burning questions were would World Champion Kasparov be disciplined or censured for his public utterance that "FIDE is like the Mafia" and would the proposed "Code of Ethics" be passed. This Code of Ethics, which seems like an oxymoron when speaking of FIDE, provided that a player could be suspended from playing chess for a period up to four years for any of a wide variety of reasons, including "any violation of the laws of chess", such as an illegal move. Can you believe that last one? One should not be surprised that when it was all over none of these things passed.
      Florencio Campomanes, the man everyone hated, proved that whatever people thought of him he was a master politician when things began to turn ugly. There was a hot debate on an African proposal. Actually, the Africans were acting as lackeys for the American representative Jerry Bibuld who proposed that Quinteros be both banned for life from playing chess and stripped of the grandmaster title. A couple of guys from Africa, Dr. Ebigwei of Nigeria and De Silva of Angola, both were in favor of the lifetime ban on Quinteros plus a one year suspension on GM Karl Robatsch of Austria, but thanks to the rep from Monaco who argued strongly against the ban calling the entire proceeding against Quinteros a "kangaroo court" conducted by persons who were not lawyers, with no right by the accused to appear in his own defense, and based upon an alleged violation of a proposed FIDE statute was just plain wrong.
      Campomanes suggested that the matter be postponed until the 1989 General Assembly meeting but that met with strong protests from the Africans so Campomanes called a brief recess to be followed by a special session to further debate the issue. Apparently nobody was willing to sacrifice their afternoon just to ban Quinteros from playing chess for the rest of his life and Robatsch for a year so there was no further discussion of the matter.
      The whole flap was a result of resolution which said that any internationally titled person who played or participated in any chess competition in South Africa could be banned from chess for life. Quinteros’ crime was that he again went to South Africa after having been suspended from FIDE competition for three years by the 1987 FIDE General Assembly. Quinteros received 125,000 Rand for his second appearance which he said was more than he got from a whole year of playing chess so he went anyway. This would have amounted to about $35,000 in today’s buying power; it was a princely sum in those days. Robatsch received a similar amount.
      If you have ever wondered just how good a GM is, even a garden variety GM like Quinteros, I once saw him playing time handicap games at $20 a pop against a local master. The master had 5 minutes on his clock while Quinteros had only one. In the 3-4 games I watched the master lost all of them.
      Oh, yeah…I almost forgot. Here’s the game.

Ivkov’s Collapse at the 1965 Capablanca Memorial

     Borislav Ivkov (born November 12, 1933) is a Serbian GM. He was a World championship candidate in 1965, and played in four more Interzonal tournaments (1967, 1970, 1973, and 1979) and won the Yugoslav Championship three times: (1958 joint, 1963 joint, 1972). He was also the first World Junior Champion in 1951. 
     The 4th Capablanca Memorial was held in Havana at the Habana Libre hotel from August 25 to September 26, 1965 under the patronage of Che Guevara who was the director of the Cuban National Bank and Minister of Industry. 
     It was the first international tournament in which Bobby Fischer would be participating since the Curacao Candidates in 1962. Fischer agreed to attend for a $3,000 appearance fee. Diplomatic relations between the United States and Cuba were still severely strained, though communications were easing and at first it seemed Fischer would have no trouble traveling there because the State Department often permitted newsmen and correspondents access to Cuba and other off limits countries even if ordinary citizens were denied visits. But the State Department wouldn’t fall for the line that Fischer was a legitimate columnist and therefore denied him a visa. 
     As a result, Fischer ended up playing by telex from the Manhattan Chess Club which ended up costing the organizers over $10,000 which is a whopping $85,000 in today’s dollars.

     This tournament would mark the first time Fischer would be facing a number of the strongest Soviet players after he had hurled accusations against them for conspiring to keep him from winning the Candidates Tournament to challenge Botvinnik in 1963. 


     The surprise of the tournament turned out to be Yugoslavia’s Borislav Ivkov who was on a roll...he had recently finished tied first with Wolfgang Uhlmann and a full point ahead of Petrosian at Zageb.
     Earlier in this tournament Ivkov had defeated both Smyslov and Fischer and after 17 rounds Ivkov and Smyslov were tied for the lead a full point ahead of Geller and a point and a half ahead of Fischer. 
     In round 18, Ivkov won, Smyslov drew, Geller won, Fischer lost. That put Ivkov half a point ahead of Smyslov and one ahead of Geller. 
     Then in round 19, Ivkov and Geller drew their games while Smyslov lost to one of the tailenders, Eleazar Jimenez. 
     With two rounds to play Ivkov was a point ahead of Smyslov and Geller and 2 ahead of Fischer and Kholmov. In round 20 Smyslov and Geller met and played the inevitable draw, while Ivkov was facing one of the hapless last place finishers Gilberto Garcia whom he was absolutely crushing...until he got into severe time pressure, blundered and lost. 
     Ivkov’s surprising loss left the door open in the last round for Geller and Smyslov. Geller only got a draw, but Smyslov won and as a result took first place. And Ivkov? He lost in the last round to Karl Robatsch. However, Ivkov did manage to win the Capa Memorial 20 years later, in 1985. Chess,com has a nice article on Ivkov HERE.  

1) Smyslov 15.5 
2-4) Ivkov, Geller and Fischer 15.0 
5) Kholmov 14.5 
6) Pachman 13.0 
7) Robatsch 12.5

21-22) Perez and Garcia 4.0

Weinstein Upsets Shamkovich

    
It doesn’t seem that long ago, but 1975 was 50 years ago. I wasn’t into music, but the disco craze was in full swing, mood rings became a popular fad and at the age of 19, Bill Gates co-founded Microsoft. 
    The world’s top rated players were 1) Bobby Fischer (2780), 2) Anatoly Karpov (2705), Vikto Korchnoi (2665), 4-6) Tigran Petrosian, Lev Poligayevsky (2645), and Mikhail Tal (2645), 7) Lajos Portisch (2635), 8-9) Bent Larsen and Boris Spassky (2625), Robert Huebner and Ljubomir Ljubojevi (2615).
    Bobby Fischer and FIDE failed to agree on the terms, some of which were quite radical, for Fischer’s defense of his world title. It’s just my opinion, but I believe he had a fear of losing to Karpov. 
    Fischer did not play from 1973 to 1991. He re-emerged to play a match against Boris Spassky in 1992, making the ridiculous claim he was still the World Champion and he was defending his title. He then retired from chess permanently. By that time chess had moved on, Fischer was a washed up champion and it was no great loss. 
 A number of players died that year. The best known being Paul Keres, Friedrich Samisch, Lajos Steiner, Nicolas Rossolimo, Karel Opocensky, Hans Johner, Vladimir Vukovic, Georg Kieninger, Abraham Baratz, Norman T/ Whitaker and John Morrison. 
    In US chess news, the US Championship and World Championship Zonal tournament took place in the small college town of Oberlin, Ohio. Walter Browne won with a score of 8.5-4.5. Also qualifying for the Interzonal was Kenneth Rogoff. Local favorite, Dr. Milan Vukcevich of Mentor, Ohio, just missed qualifying; he finished 3rd with 7.5-5.5, a half point behind Rogoff. 
    Today’s game comes from the Louis D. Statham Masters-Plus Championship (aka Lome Pine) that was won by Vladimir Liberzon. This was the fifth annual Lone Pine tournament and it set a world record in the number of International Grandmasters participating. . 
    Statham had invited literally every Grandmaster in the world to compete and guaranteed them that their air fare would be paid even if they failed to win a prize. It was unfortunate that the number of GMs was reduced due to politics. For example, three string Czech players were forced to withdraw: Jan Smejkal, Vastimil Jansa and Miroslav Filip. The reason? Their federation could not be given a guarantee that dissident Czech GM Ludek Pachman, who at the time was Stateless, would not be playing. 
    For those not familiar with Jansa, he had won the strong Atlantic Open on tiebreaks ahead of Matanovic, Bisguier. Zuckerman and 8almazi in New York City the previous November and his 2540 rating tied him for places 36-41 in the world. As for Pachman, he did not play at Lone Pine. 
    The surprise winner of this game was Norman Weinstein (born in 1950) who was awarded the IM title in 1973, the same year he won the US Open Championship. His opponent was GM Leonid Shamkovich ( 1923-2005) who was originally a Soviet player, but in 1965 he emigrated to the US by way of Israel and Canada. He lived in Brooklyn.

Szabo Smashes Hort at Sarajevo

     One of the longest tournament series is Sarajevo which used to be in Yugoslavia, but today is in Bosnia and Herzegovina. Chess has long been very popular there and even today visitors comment on the street games that are commonly seen. 
     The list of great players in the Sarajevo tournaments is as long as your arm: Spassky, Petrosian, Keres, Kotov, Simagin, Szabo, Eliskases, Larsen, Andersson, Lobron, Darga, Robatsch, Benko, Browne, R. Byrne, Seirawan, Pirc, Velimirovic, Adorjan, Csom, Ribli, Sax, Smejkal, Hort, Jansa, Kavalek, Yusupov, Vaganian, Romanishin, Bareev, Van der Wiel, Piket, Bacrot, Miles, Short, Adams, Leko, Radjabov, Topalov and many others. 
     The winner of the first tournament was Stojan Puc (1921-2004) in 1957, plus he tied with Ludek Pachman for first in 1960. The most first prizes went to Viktor Korchnoi (1969, 1984 shared and 1998) and Lajos Portisch (1962 shared, 1963, and 1986 shared). Several players have won the tournament twice: Kasparov, Ivkov, Gligoric, Pachman, Puc, Ciric, Georgiev, Psakhis, Ivan Sokolov and Movsesian. 
     In spite of all the great players who have played there, as far back as the 1972 tournament Paul Keres complained that the tendency for Grandmaster draws was prevalent and the new goal of the GM was no longer to checkmate the enemy King, but to score points. 
     Back in the 1960s (or was it the 1970s, I am not sure) Nicolas Rossolimo bitterly complained that by FIDE rules in effect at the time he had become listed as "inactive" which made it almost impossible for him to get invitations to tournaments. He also complained that despite his many previous successes in international tournaments, many brilliancy prizes and Queen sacrifices, that when he went to publish a book of his best games, he was told by publishers that they were not interested because he "did not score points." 
     Rossolimo was so frustrated that he added he thought that in each tournament a committee should be formed to judge the games and award points based on beauty. Under this crazy system in some cases it could be possible for the loser to score more points than the winner if he played more beautifully! 
     Sarajevo had a reputation for a high number of Grandmaster draws, but the 1972 tournament was a refreshing exception. The winner of the following game was the great Hungarian GM Laszlo Szabo (March 19, 1917-August 8, 1998, 81 years old). 
     Szabo was born in Budapest and at the age of eighteen, he won the Hungarian Championship for the first of nine times (1935, 1937, 1939, 1946, 1950, 1952, 1954, 1959, and 1967/68). 
     Before World War II, he worked in the foreign exchange department of a Budapest bank. During World War II, he was in a Hungarian Forced Labor unit where he was captured by the Russian army and was a prisoner of war until after the end of the war. Following the Second World War, he began to compete in major international events and ontinued to play in tournaments and promote chess in his country until his death in 1998. Unofficially Chessmetrics assigns him a high rating of 2726 in 1946 which ranked him number 6 in the world behind Botvinnik, Najdorf, Euwe, Kers and Smyslov. 
     His opponent, Vlastimil Hort (January 12, 1944), is a Czech GM who during the 1960s and 1970s was one of the world's top players and reached the 1977–78 Candidates Tournament. Hort defected in 1985, moving to West Germany. 
     I analyzed this game using Stockfish and Komodo and in doing so, as often happens, I ran into a couple of positions where the engines were showing a winning advantage for, in this case, white, but being the patzer that I am I did not see how. In those cases I ran a Shootout just to make sure and to get an idea of the winning technique. In a Shootout the program (Fritz) plays a series of rapid games (either using a specified time or number of plies). 
     This brings me to a very informative article that appears in the recent issue of Chess Life in which GM Jacob Aagaard discusses analyzing with engines. Naturally I can't reproduce the five page atricle, but he makes some instructive observations on using engines to improve your play.
     When analyzing with an engine we are usually tempted to insert a whole lot of long and superfluous variations into the game. We should only be interested in variations that we, as humans, should actually be able see and then base our judgment on that. 
     He also noted that often we aren't going to understand why engines are giving one side and advantage. In those cases, further investigation is warranted and, hopefully, we will reach an understanding of why one side is better. If you can explain why one side is better in a way that another person can understand it then you have it. 
     By the way, Aagaard is an outstanding author and I can highly recommend his book Excelling At Chess Calculation, but only if you are willing to put in a LOT of work.

Gruenfeld Defense

[...] 1.d4 ♘f6 2.c4 g6 3.♘c3 d5 The Gruenfeld gives white the chance to gain the Pawn center which back in the 1920s was a revolutionary hypermodern idea. In those days the large P-center was considered to be a huge advantage that lead to a strong attack. However, black has plenty of opportunities for counterattack. At one time the defense was a favorite of Reshevsky because he considered it a "fighting defense." 4.cxd5 White takes the opportunity to kick the N around and set up an imposing P center. Seen less often are 4.Nf3, 4.Bg5 and 4.Bf4, all reasonable moves. 4...♘xd5 5.e4 ♘xc3 Probably the best reply. 6.bxc3 ♗g7 7.♗c4 One of 19 (!) moves that white has tried according to my Fritz opening book. 7...c5 8.♘e2 By far the best move.
8.♘f3 looks reasonable, but after 8...O-O 9.O-O cxd4 10.cxd4 ♘c6 11.♗e3 ♗g4 black has scored quite well.
8...♘c6 9.♗e3 O-O 10.O-O ♕c7 11.♖c1 ♖d8 12.f4 This is all opening theory and here white has tried 17 different moves!! Black now begins pecking away at white's center forcing it to advance. What will the result be? 12...♗g4 13.f5 ♘a5 14.♗d3 ♕d7 15.d5
15.e5 Is another alternative, but it, too, favors black. 15...♗xe5 16.fxg6 hxg6 17.h3 ♗xe2 18.♗xe2 cxd4 19.cxd4 ♗xd4 20.♗xd4 ♕xd4+ 21.♕xd4 ♖xd4 with a won ending for black. Chirivi C,A (2040)-Diaz Arboleda,D (2124)/Medellin 2013.
15...gxf5 16.c4 b5 This is one way to attack white's center. Another was is ... fxe4 and ...e6.
16...fxe4 17.♗xe4 e6 18.♕e1 b6 19.♘f4 e5 20.♘e6 fxe6 21.♕h4 and white's K-side attack prevailed. Kiese,M-Steinmueller,S/Berlin 1991
17.h3 fxe4
17...bxc4? would be great except for 18.♗b1 ♗d4 19.♗xd4 ♗xe2 20.♕xe2 cxd4 21.♖xf5 and white has a huge positional advantage because black's Ps are too weak.
18.♗xe4 Black has a couple of interesting replies here. 18...♗h5 Best as with this move black retains equality.
18...♗xh3 looks promising because if 19.gxh3 ♕xh3 20.♗xc5 bxc4 21.♗g2 Black has 3Ps for the B, but both Stockfish and Komodo highly favor white. In a Shootout using Stockfish white scored 7 wins in the resulting ending.
18...♘xc4 does not work out well either after 19.♖xc4 bxc4 20.hxg4 ♕xg4 21.♕c2 and white is better. In Shootouts white won all 7 games.
19.cxb5 ♖ac8 This loses outright as will be clear next move.
19...♕xb5 attacks the N and so 20.♗f3 ♗xf3 21.♖xf3 ♘c4 equalizes
20.♕e1 Unpinning the N. 20...♕xb5 21.♘f4 With the N no longer pinned white can now conduct an attack on black's K. 21...♗g6 22.♘xg6 fxg6 23.♗g5 ♗f6 24.♗xf6 exf6 It appears the black has solved his problems on the K-side and with the reduced material the danger of a direct attack on his K has disappeared. 25.♗xg6 But appearances can be deceptive. 25...♖f8 Surprisingly, white now has another sacrifice available. (25...hxg6 26.♖xf6 ♕e8 27.♖e6 ♕f7 28.♕e4 ♔h7 29.♖f1 ♕g7 30.♖e7 wins.) 26.♕g3
26.♗xh7+ Although this would win in the ending, it's much too unclear to play OTB! 26...♔xh7 27.♕h4+ ♔g8 28.♕g4+ ♔f7 29.♕f5 and black's extra piece won't save him as extensive endgame analysis shows. That's assuming that white finds the best moves at every turn.
26...♔h8 (26...hxg6 27.♕xg6+ ♔h8 28.♖f5 is the end.) 27.♗xh7 A brilliant finish. 27...♕b2
27...♔xh7 28.♖f4 and black has no way out. The difference between this variation and 26.Bxh7+ is that here white's Q is better positioned in that it cuts off black's K.
28.♗f5 ♕d4+ 29.♔h1 ♖g8 30.♕f3 ♖ce8 31.♕h5+ ♔g7 32.♕h7+ Hort resigned.
32.♕h7+ ♔f8 33.♗e6 ♖xe6 34.dxe6 ♖g7 35.♕h8+ ♖g8 36.♖xf6+ ♔e7 37.♖f7+ ♔d6 38.♕xg8 ♔c6 39.e7 c4 40.e8=♕+ ♔b6 41.♕b8+ ♘b7 42.♖xb7+ ♔a5 43.♕g5+ ♔a4 44.♕b5+ ♔a3 45.♕a6#
32.♖ce1 is actually a quicker mate. 32...♖xe1 33.♖xe1 ♕e5 34.♖xe5 fxe5 35.♕g6+ ♔f8 36.♕f6+ ♔e8 37.d6 ♖g7 38.♕xg7 c4 39.♕g8#
