Surprises At Praia da Rocha, 1969

     In 1969 there were three zonal tournaments in Europe: Raach, won by Uhlmann with Andersson, Ivlov, Portisch and Smejkal tied for second. Athens was won by Matulovic with Hort and Huebner tied for second. 

     The third Zonal was held in Praia da Rocha, Portugal. The tournament was originally scheduled for twenty players, but at the last minute the players from Holland and Tunisia canceled. 

     Praia da Rocha was the weakest of the European zonals and the participants in the other two have complained that it was easier for those in Portugal to attain to the goal of qualifying for the Interzonal. Even so, Gligoric of Yugoslavia, who was considered the prime favorite, had his problems and his qualification was in doubt until the end when he managed to qualify by scoring nine points in the last ten rounds. For the results of all the Zonals that year refer to Mark Weeks post HERE.

     The high finish of Dr. Miroslav Filip of Czechoslovakia was something of a surprise and when Dragoljub Minic of Yugoslavia scored six and a half points in the last seven rounds to take first place that was also a surprise. 

     Italy's Sergio Mariotti, who scored 9 points in the last 10 rounds, could have been a major surprise if he hadn't blundered against the lowly placed Belgian Helmut Schumacher and the South African Brian Donnelly. 

     England's William Hartston was also a very serious rival for first until he lost his last four games! Among other surprises were the showing of Bulgarian GM Milko Bobotsov who collapsed at the very end and Hungarian GM Istvan Bilek who was completly out of form. In the end, in tie break order, the qualifiers were Minic, Filip and Gligoric. 

     This was the first time Portugal was host to such an important chess event and although Filip thought it was was one of the best organized of tournaments he had played in, some of the other players did a lot of bellyaching. 

     Gligoric complained about dogs barking all night and the early morning noise, but it was also noted that he spent a lot of late nights analyzing and stuff. Scotland's David Levy complained that the Spaniards and Portuguese were put up in better hotels than the foreigners and that the foreigners held their own special tournament to see who would find the most flies on their plate. 

     Pre-tournament favorite Gligoric took a gut punch from Italy's champion Mariotti who upset him in sensational style early on. Mariotti's fourth place finish was one place away from Interzonal qualification. 

 

     Sergio Mariotti (born August 10, 1946) is the first Italian to achieve the GM title which he was awarded in 1974. Born in Florence, he became the Italian junior champion in 1965 and in 1969 the Italian Champion. After several successes in the early to mid-1970s the British Chess Magazine nicknamed him "The Italian Fury" due to his collection of tournament wins and his enterprising, tactical style. His preferred openings are, with either color, the Sicilian and the Ruy Lopez with an occasional Evans Gambit or Albin Counter Gambit thrown in.

     Yugoslav GM Svetozar Gligoric (February 2, 1923 – August 14, 2012) won the championship of Yugoslavia a record twelve times, and is considered the best player ever from Serbia. In the 1950s and 1960s, Gligoric, who was fluent in several languages, was not only one of the top players in the world, but he was also among the world's most popular players. Although he compiled a superb tournament record he is best known as an openings theorist who made enormous contributions to the theory and practice of the King's Indian Defense, Ruy Lopez and Nimzo-Indian Defense, among others.

King's Indian: Four Pawns Attack

[...] 1.d4 ♘f6 2.c4 g6 3.♘c3 ♗g7 4.e4 d6 5.f4 Mariotti was a fearless player and it's hard to say if his decision to play the grandiose Four Ps Attack was courageous or foolhardy because Gligoric was born playing the K-Indian. This formation has never attracted serious interest although Alekhine used it three times at New York 1924 and scored +1-0=2. In his day Bent Larsen occasionally experimented with it. 5...c5 For years this was the standard response. White can now choose between hte Benoni-like 6.d5 with sharp play or the more restrained 6.dxc5 or 6.Nf3 6.d5 On rare occasions white has tried the hyper-aggressive 6.e5 with mixed results. 6...O-O 7.♗e2

7.♘f3 is usually played. 7...e6 8.♗e2 exd5 9.cxd5 ♗g4 10.O-O with a sharp position resembling those of the Benoni.

7...e6 8.dxe6 Black now faces a conundrum. Should he recapture with the P or B? Capturing with the B is more cautious and prevents the complications that arise in the game. 8...fxe6 It's possible Gligoric chose this because it leads to complications and as an experienced GM he may have felt he could outplay his young and inexperienced opponent.

8...♗xe6 This is the most popular choice and it serves black well. 9.♘f3 ♘c6 10.O-O and black is well developed and controls d5 sufficiently so that the weaknes of the P on d6 is of little significance.

9.g4 Talk about courageous and enterprising! Apparently Mariotti was trying to present the old man with new problems in unfamiliar territory.

9.♘f3 ♘c6 10.O-O a6 11.♔h1 b6 12.♗e3 is perfectly even. Fries-Nielsen,J (2454)-Mortensen,E (2441)/Greve DEN 2002

9...♘c6 10.h4

10.g5 looks promising but after 10...♘e8 11.h4 e5 White is pretty much committed to continuing hyper-aggressively and things turn out to be in black's favor after 12.f5 gxf5 13.h5 ♘d4

10...♘d4 11.h5 d5 Mariotti's strategy has brought him success! Gligoric proceeds on the rule that the best defense against a flank attack is the counter attack in the center. But here it's the wrong strategy because after 11...d5? white's Q penetrates on to the opened h-file and gives white some serious play.

11...a6 12.hxg6 hxg6 13.g5 ♘h7 14.♗d3 and now with 14...b5 black has equalized. Instead he played the inferior 14... e4 and got a losing game. Bleis,C-Kabisch,T (2285)/Niedersachsen 1989

11...b5 Is the correct strategy. Then after 12.hxg6 ♗b7 13.gxh7+ ♔h8 with the upper hand because white has no good way of meeting the attack on e4. 14.♗d3 b4 15.♘ce2 ♘xe4

12.e5 After this white has a really nice game. 12...♘e4 The strength of black's Ps and Ns in the center are an illusion because white has a powerful attack against black's K. 13.hxg6 hxg6 14.♕d3 Also good was 14. Bd3. 14...b5 This move may be typical in similar positions, but here it leads to problems.

14...♗d7 leads to equality after 15.cxd5 exd5 16.♘xe4 dxe4 17.♕xe4 ♘xe2 18.♕xe2 ♗c6 Black is a P down but he has sufficient play because white's K is precariously placed int he center.

15.♘xe4 This is the correct reply. (15.♘xb5 ♘xb5 16.cxb5 c4 with a dangerous initiative.)

15.cxb5 is successfully met by 15...♕a5 16.♘f3 ♘xe2 17.♕xe2 ♘xc3

15...bxc4 16.♕h3 dxe4 17.♕h7+ ♔f7 18.f5 White doesn't care about material. He is interested in attacking black's exposed K. 18...exf5 19.♖h6

19.♗xc4+ was even more forceful. Then if 19...♗e6 20.♗xe6+ ♘xe6 21.♖h6 f4 22.♕xg6+ ♔g8 23.♕h7+ ♔f7 24.♘h3 ♕e7 25.♘xf4 ♘xf4 26.♗xf4 ♖h8 27.♕g6+ ♔g8 28.♖xh8+ ♔xh8 29.O-O-O and even with the reduced material white has a winning attack.

(19.♗xc4+ ♘e6 20.♗h6 is fatal for black.) 19...♘c2+ 20.♔f1 fxg4

20...♘xa1 21.♕xg6+ leads to mate after 21...♔e7 22.♕xg7+ ♔e8 23.♕g6+ ♔d7 24.♖h7+ mates in 3.

21.♔g2 ♘e1+

21...♕d5 offered more resistance. 22.♕xg6+ ♔g8 23.♕h7+ ♔f7 24.♖d6 ♘e1+ 25.♔h1 ♖h8 26.♕xh8 ♗xh8 27.♖xd5 ♗e6 28.♖xc5 ♗xe5 29.♖xe5 ♖h8+ 30.♘h3 ♖xh3+ 31.♔g1 ♘f3+ 32.♗xf3 exf3 33.♗f4 g3 34.♖g5 and in this position white is winning.

22.♔h1 ♘d3 Black has prevented the deadly B check Bxc4+, but new threats are present and kill all hope. (22...♗f5 is still a small chance 23.♗xc4+ ♔e8+⁠−) 23.♕xg6+ ♔g8 24.♕h7+ ♔f7 25.♗e3 ♕e7 26.♖f1+ ♔e8 27.♕g6+ ♖f7 28.♕c6+ ♕d7 29.♖e6+

29.♕xa8 is no so effective as after 29...♗xh6 30.♗xh6 ♘xb2 black has some fight left in him.

29...♔f8 30.♗xc5+ ♘xc5

30...♔g8 what else? 31.♖e8+ ♔h7 32.♕xe4+ ♖f5 33.♖xc8 ♖xc8 34.♖xf5 ♕c6 35.♕xc6 ♖xc6+⁠−

31.♕xc5+ ♔g8 32.♖d6 ♕b7

32...♕c7 a last effort to resist the inevitable 33.♖c6 ♕xe5 34.♗xc4 ♕xc5 35.♖xc5 ♗a6 36.♗xf7+ ♔f8 37.♗c4+ ♔e7 38.♗xa6 ♗xb2+⁠−

33.♖xf7 ♔xf7 34.♗xc4+ ♔e8 35.♗d5 ♕e7 36.♕c6+ ♔f8 37.♕xa8 ♕h4+ 38.♔g2

38.♔g2 ♕g3+ 39.♔xg3 ♗xe5+ 40.♔g2 ♗xd6 41.♕xc8+ ♔g7 42.♕xg4+ ♔f6 43.♕e6+ ♔g7 44.♕f7+ ♔h6 45.♗xe4 ♔g5 46.♕f5+ ♔h6 47.♕g6#

Review ChessOK Aquarium 2020

 

     Last month I did a brief post advising readers that ChessOK Aquarium 2020 (download version) was on sale at half price for 19.98 Euros which is US $23.64.  As you are probably aware, for sometime I have been using my old Aquarium 2014 to post games. 

     The other day when I got a notice that this blog had made a few dollars I was able to download the 2020 version without any out of pocket expense.

     Aquarium 2020 is a great deal even at full price, but how does it compare to the 2014 version? 

     Honestly, I'm not interested in access to 60-plus improvement courses nor the 7.3 million game database. The improvement ship sailed a long time ago and my database is already pretty much up to date. Access to the Lomonosov 7-piece tablebases is nice though. 

     I don't really have the desire, or the need, to subject a position to exhaustive overnight analysis, so the IDeA analysis feature really isn't a selling point for me. Neither is playing against the engine something I want to do. 

     One nice feature is the improvement to Infinite Analysis. With other programs as soon as you shut the engine down or switch to another task the analysis disappears and you have to start over again. Aquarium 2020 stores your infinite analysis results so if you run into the same position, even in a different database and if it came up through a different move order, you can see that you have analyzed it before. You can also add a column with the infinite analysis tree to a tree configuration, so you can always see the evaluation of the different moves in the tree window. And, if you use multiple chess engines the analysis results and trees can be stored separately for each engine. All very nice features, but, again, I don't need all that information because not being a serious player, I'll probably never analyze the same position twice. 

     What I was curious about was seeing if there was anything different or better when it comes to posting games in the blog. Using the "HTML for export" function produces a very nice blog appearance except that squares with pieces on them are displayed as white squares and the code is often 90-100 pages long in 12 pt. font in Word which translates to thousands of lines in HTML in Blogger. That means I have to use the "iBook for HTML" command and the game will only be about 14 pages long and a whole lot less lines of code in Blogger! 

     When it comes to posting games in Blogger I'm afraid Aquarium 2020 is a bust. The problem is that when posting a game in iBook for HTML in Blogger you get something like this: 

 

     While you can still play through the game OK, the piece notation does not show up properly. I am not sure what the reason for this is, but looking at the HTML code it seems to have something to do with the way 2020 writes it and I am not computer savvy enough to figure out what the problem is.  

     What I did notice is that in the lines of code in the 2020 version "CA Chess" (a font) appears a lot whereas in the 2014 version it does not appear at all. I suspect this is the problem.

     The bottom line is that while Aquarium 2020 is an excellent program that does a lot of things, it does not meet my specific needs and now I have another unused chess program sitting on my old laptop.

Hullabaloo at Hastings in 1961

     Who can forget 1961? The Berlin Wall dividing East and West Germany was built. Thanks to President John F. Kennedy's bumbling, American backed Cuban exiles were slaughtered when they attempted to invade Cuba at the Bay of Pigs. Soviet cosmonaut Yuri Gagarin completed the first orbit of Earth by a human.

     Americans made a song titled Tossin' and Turnin' by some guy named Bobby Lewis the country's top song and the big movies that year were 101 Dalmatians, West Side Story and The Parent Trap. 

     In Lancaster, New Hampshire Betty and Barney Hill were abducted and examined by aliens; at least that's what they claimed. And Morley cigarettes became popular. 

     Over in England, in 1961 the farthing coin, used since the thirteenth century, ceased to be legal tender as did black and white £5 notes. Members of the Soviet Portland Spy Ring were arrested in London; they were accused of passing nuclear secrets to the Soviet Union. The top TV shows in England were the Royal Variety Show, No Hiding Place, Sunday Night at the Palladium, Coronation Street and the Army Game. 

     The year ended with a bang when the 37th Hastings Christmas Chess Festival began on December 27; it ended January 5, 1962. In the Premier event the featured players were world champion Mikhail Botvinnik, four-time Hastings champion Svetozar Gligoric and famous Russian GM Salo Flohr. Botvinnik became the first reigning world champion to win the tournament. 

     It was at this tournament that England's John Littlewood played his most famous game...a whirlwind attack against Botvinnik. It failed and Botvinnik won, but the game was published everywhere as players marveled at Littlewood's panache. Littlewood also played (and won) a ripsnorter against Arthur Bisguier. After the game Bisguier asked, "What do you feed this guy on - raw meat?"  

     The tournament was also famous because the US women's champion, beauty queen and media darling Lisa Lane withdrew after she had two losses, a draw and one adjourned game in a reserve event claiming she was homesick and in love with her future second husband Neil Hickey. A more likely reason was that she hated to lose and wasn't living up to the hype and her expectations. In an interview she stated she hated anybody who beat her. Within a few years she quit chess and even refused to talk about it. Read a Sports llustrated article

     It's not clear which Reserve tournament Lane was playing in. The Premier Reserve tournament was won by Manfred Mannke, Sr. of Germany and Drazen Marovic of Yugoslavia. Mannke died at the age of 27 on August 15, 1962 as a result of a car accident on the road between Sieradz and Lodz in Poland. Dragoljub Velimirovic finished third. 

     The Reserves A event was won by Dragoljub Baretic. An FIDE Master, Baretic is a well known blind player, but I was unable to establish when he lost his sight. The Reserve B was won by David Wells and the Reserve C by Peter Hempson. The Reserve D was won by Rudolf Bendenbender 

     Littlewood wasn't the only player to have played some hair raising games. The Gligoric - Bisguier was also one such game. On move 16 Gligoric shocked Bisguier with a B sacrifice. Bisguier realized he had blundered and after some thought concluded that if he took the B, Gligoric had another B sacrifice that would win. Left with little choice, Bisguier declined the B and settled for just the loss of a P. Even after the loss of a P, Bisguier was still in serious danger from Gligoric's Bs, but he was able to use the time Gligoric lost in retreating the proffered B to initiate a sacrificial attack of his own.

Queen's Gambit Declined

[...] 1.d4 ♘f6 2.c4 e6 3.♘c3 d5 4.♗g5 ♗e7 5.e3 O-O 6.♘f3 ♘bd7 7.♖c1 a6 In this position white will normally play 8.cxd5. Thus, the purpose of this move is to gain a tempo if white elects to play the Exchange Variation because the R usually has to return to b1 in order to support the advance b2-b4. 8.cxd5 exd5 9.♗d3 c6 10.♕c2 To sum up so far: White has control of the c-file, his Q and B are lined up on h7 and his B on g5 exerts annoying pressure on black. For his part, black's immediate problem is to complete his development, especially getting his light squared B into play. 10...♖e8 Making room for the N.

10...♘b6 This opens up the diagonal for the B, but it doesn't work... 11.♗xf6 ♗xf6 12.♗xh7+ winning a P and seriously weakening black's K.

11.O-O ♘f8 12.♘a4

12.♖b1 leads to the Minority Attack which many years ago was a favorite of Reshevsky. And, in Modern Chess Strategy, Pachman devoted a lot of space to the Minority Attack. Nowadays it has lost it's sting. 12...♘g6 13.b4 ♘e4 14.♗xe7 ♕xe7 15.a4 ♘xc3 16.♕xc3 with equal chances.

12...♘g6 The N shields the h-Pawn.

12...♘e4 This is often an effective black strategy in the Exchange Variation; black changes the P-structure. 13.♗xe7 ♕xe7 14.♗xe4 dxe4 15.♘d2 ♗f5

13.♘d2

13.♘c5 ♘d7 14.♗xe7 ♕xe7 15.b4 ♘df8 16.♖fe1 is equal. Klauser,M (2345)-Begovac,F (2425)/ Switzerland 1995

13.♕b3 ♘g4 14.♗xe7 ♖xe7 15.♘b6 ♖b8 16.♕b4 with equal chances. Gheorghiu,F (2495)-Begovac,F (2405)/Bern 1991

13...♗d6 Interesting. This leaves his N pinned, but at the same time he threatens ... Bxh2+ 14.g3 his is questionable. It defends against the threat of ...Bxh2 but at the same time it creates a weakness on the light squares around his K.

14.♗xf6 This eliminates the threat to h2 but it also surrenders the two Bs. 14...♕xf6 15.♘b6 ♖b8 16.♘xc8 is equal.

(14.♗xf6 ♕xf6 15.♘b6 ♖b8 16.♘xc8 ♖bxc8) 14...♗h3 15.♖fe1 h6 Forcing the exchange of the B which has no good square to which it can retreat.. Black threatens to win material: h6xg5 (15...♘f8!? should be investigated more closely) 16.♗xh6⩲ It's somewhat surprising that the tactician Bisguier didn't see this. 16...♘e4 Letting Gligoric have the P is a wise decision because black has some compensation in the form of counterplay on the K-side.

16...gxh6 would make survival difficult, but not impossible. 17.♗xg6 fxg6 18.♕xg6+ ♔f8 19.♕xh6+ and wins.

16...gxh6 17.♗xg6 The best defense is now 17...b5 18.♘c3 ♕d7 19.♗d3 ♖ac8 to support the advance of the c-Pawn, but here white is better.

17.♗f4

17.♘xe4 Or 17.Bxe4 allows unclear complications. 17...dxe4 18.♗xe4 ♖xe4 19.♕xe4 gxh6

(Inferior is 17.♘xe4 dxe4 18.♗xe4 ♖xe4 19.♕xe4 gxh6∓) 17...♘xf4

17...♗b4 18.♘c3 (18.♘xe4? is very tempting, but 18...dxe4 19.♗xe4 ♘xf4−⁠+)

18.♗xe4 dxe4 19.♘c3 ♗xc3 (19...♘xf4 20.exf4 ♕xd4 21.♘dxe4±) 20.♕xc3 ♕d7⩱

18...♘xd2 19.♕xd2⩲

18.exf4±

18.gxf4 On this move black gains the upper hand with 18...Qh4, but Bisguier intended a clever N sacrifice on f2. 18...♘xf2 19.♔xf2 ♕h4+ 20.♔e2 ♖xe3+ 21.♔xe3 ♗xf4+ 22.♔e2 ♖e8+ 23.♗e4 ♖xe4+ 24.♕xe4 (24.♘xe4 ♕g4+ 25.♔d3 ♕f3+ 26.♖e3 ♕xe3#) 24...dxe4 25.♘xe4 ♗xc1 26.♖xc1 ♕xe4+ 27.♔f2 ♕f4+ and wins

18.gxf4 White is not obligated to take the N. 18...♘xf2 19.♗h7+ ♔f8 20.♘f3 ♘e4 21.♗xe4 dxe4 22.♘e5 and black's advantage is minimal.

18...♗xf4 No prosaic 18...Nxd2 with equality for Bisguier. Instead he prefers to offer his own B for a dangerous attack on Gligoric's K. 19.gxf4 ♕h4 20.♘f1 Being a piece ahead and facing a dangerous attack, Gligoric begins building a defense for his K. In his book The Art of Bisguier (Vol 2), Bisguier is guilty of producing some incredibly sloppy analysis of this position even though in some games in the book he said he used Fritz 8. His analysis of this position is so bad I will not even quote it because it looks like something he dashed out without actually checking everything.

20.♗xe4 loses to 20...♖xe4 21.♕b3 (21.♘xe4 ♕g4+ mates) 21...♖xf4 22.♕g3 ♖g4

20.♘xe4 eliminating some attackers was a plausible course. 20...dxe4

20...♖xe4 favors white after 21.♖e3!21...♖xe3 22.fxe3 ♕g4+ 23.♔f2 and white has escaped.

21.♗xe4 ♖xe4 22.♕xe4 ♕g4+ 23.♔h1 f5 24.♖g1 fxe4 25.♖xg4 ♗xg4 with equal chances.

20...♕xf4 21.♖e3 This move forfeits the advantage.

21.♗xe4 was stronger. 21...♕g4+ 22.♘g3 ♖xe4 23.♖e3 and white is better.

21...♘g5 This is certainly not bad, but 21...Qg5 was interesting.

21...♕g5+ 22.♘g3 And black has an interesting sacrifice on f2. 22...♘xf2 23.♗h7+ ♔h8 24.♖ee1

24.♖xe8+ ♖xe8 and the threat of ...Re1+ can't be met in any satisfactory way.

24...♘e4 25.♗xe4 ♖xe4 26.♖xe4 dxe4 27.♖e1 f5 with complications.

22.♕e2 ♖xe3

22...♗e6 introducing complications may have been a better decision. 23.♘c5 ♘h3+ 24.♔h1 ♘xf2+ 25.♔g2 ♘g4

23.fxe3 ♕f6 24.♘d2 ♖e8 25.♘c3 This allows Bisguier to keep up the pressure. (25.♔h1 ♕e7 26.♖e1 followed by Nc5 keeps the advantage.) 25...♕h6 26.♔h1 c5

26...♘f3 This was much better. After 27.♘xf3 ♖xe3 28.♕d2 ♖xd3!29.♕xh6 gxh6 30.♖g1+ ♔f8 31.♖g3 White is better, but at least black is still in the game.

27.♘xd5 cxd4 28.e4 f5 Being a P down and not really having an especially good position Bisguier is simply trying to complicate things...not a bad idea!. 29.♖g1 fxe4 Bisguier incorrectly claimed that by piling on the pinned B he would soon have his piece back. He can be forgiven for that incorrect assumption because based on his next move Gligoric apparently thought the same thing! 30.♗xe4

30.♘f4 Taking advantage of the fact that black's e-Pawn is pinned. 30...♗d7 Renewing the threat of ...exd3. 31.♗c4+ and white has escaped and keeps a slight plus. On the down side he has to deal with black's to passed Ps which it seems will be difficult, but possible.

30...♗f5 31.♕c4 ♘xe4 The only correct reply. (31...♗xe4+ 32.♘xe4 ♖xe4 33.♘f6+ ♔f8 34.♕c8+ ♔f7 35.♘xe4 wins.) (31...♖xe4 32.♘e7+ ♔f8 33.♘xf5 ♕c6 34.♕xc6 bxc6 35.♘xe4 ♘xe4 wins) 32.♘f6+ Wrong check!

32.♘e7+ The only good move. 32...♔h7 33.♘xf5 ♘f2+ 34.♔g2 ♕xd2 35.♕xd4 ♕xd4 36.♘xd4 ♘d3 with a draw.

32...♔h8 33.♘dxe4

33.♘xe8 allows a mate in four: 33...♘f2+ 34.♔g2 ♗h3+ 35.♔g3 ♕g5+ 36.♔xf2 ♕e3#

33...gxf6 34.♘d6 ♕h5 Threatening ...Qf3+ but this should have let his advantage slip away.

34...♕e3 is difficult to meet. 35.♕d5 (35.♘xf5 ♕f3+ mates in two.) 35...♗e4+ 36.♘xe4 ♕xe4+ 37.♕xe4 ♖xe4 38.♖d1 and white has a fighting chance in the ending.

35.♕xd4 Stepping on a land mine.

35.♕f1 This would have held the game 35...♖e2 36.♕f4 ♗g6 37.♖g4 ♖f2 38.♕xf2 ♕xg4 39.♕xf6+ with a draw.

35...♕f3+ Facing mate in 5 Gligoric resigned. (35...♕f3+ 36.♖g2 ♖e1+ 37.♕g1 ♗h3 38.♘f7+ ♔h7 39.♘g5+ fxg5 40.a3 ♕xg2#)
