Pushing the f-Pawn

    
In 1957 I was learning to play chess, but there were more important things going on. President Dwight Eisenhower was sworn in for a second term. 
     That year the US slipped into a recession and inflation was rampant, but it had no effect on our family because my father held onto his job as a section foreman with the Baltimore and Ohio Railroad. 
    Under executive orders from President Eisenhower, troops from the 101st Airborne Division were deployed to ensure that black children (the Little Rock Nine) were allowed to attend classes at the previously segregated Little Rock (Arkansas) Central High School. 
    In a war that was to affect me many years later, US Army Special Forces Captain Harry Cramer became America's first combat death in Vietnam. Between 1955 and 1975, there were 211,454 US casualties in Vietnam. All of then were in vain because on March 29, 1973, the last US military unit fled Vietnam in what was a complete debacle. 
    Leroy Burner, the US Surgeon General, issued a report on the evils of smoking that linked cigarettes and lung cancer. It was the year the words Asian flu, clip art, computerize, disco, doggie bag, fanny pack, happy camper, kooky, launchpad, loungewear, mainframe, opioid, RAM, refried beans, sin tax, Sputnik, and townhome all appeared in print for the first time. 
    Trolley service in both New York City and Kansas City ended. The Soviet Union inaugurated the Space Age by launching Sputnik I, the world's first artificial satellite. 
    In the year 1957, bubble wrap, Purina dog chow, Dream Whip, Formula 409 cleaner, Sweet’n Low, Tang (an orange drink mix), styrofoam coolers and Burger King’s Whopper all appeared on the market for the first time. 
    In the chess world on April 27, 1957, Vasily Smyslov defeated Mikhail Botvinnik to become the world champion. 
     Correspondence GrandmasterHarald Malmgren (1904-1957) died in Uppsula, Sweden at the age of 52. Analyst Hans Haberditz (1901-1957) died in Vienna at the age of 56. Max Pavey (1918-1957) died of leukemia in New York at the age of 39. 
    At the Massachusetts Institute of Technology a chess program fo an IBM computer eass writtem It could execute 42,000 instructions per second. It did a 4-ply (2 moves) search in 8 minutes. 
    Nobel Prize winner in economics and leader in AI and cognitive psychologist Herbert Simon said that within 10 years a computer would be the world champion. It took 40 years (1997) before a computer (Deep Blue) could defeat a world champion (Kasparov).      
    Samuel Reshevsky played Donald Byrne in a match in New York. The match struck a snag in the first game. Reshevsky, who had failed to notice that Byrne’s flag had fallen, offered a draw which Byrne accepted and the result stood. In the second game Byrne’s flag fell again and guess what? Reshevsky did not notice it. Then Reshevsky's flag fell, but Byrne failed to notice it! 
    Reshvsky’s wife was sitting in the audience claimed the win for her husband! Byrne pointed out that only the player on the move could claim a time forfeit. Since it was now Byrne’s move, he claimed the win on time even though his flag was also down. 
    An appeals committee was organized to settle the dispute, but Byrne objected. The committee declared that the game was drawn and Byrne then walked out. He later returned and lost decisively by a score of 7-3. 
    Bobby Fischer played two games against former world champion Max Euwe at the Manhattan Chess Club in New York, drawing one and losing one. Euwe was paid $65 (a little over $600 today) and Fischer was paid $35 (not quite $400 today). 
    The 14-year old Fischer tied for 1st-2nd (scoring 10-12) with Arthur Bisguier at the 58th US Open in Cleveland, Ohio. He won on tie-break, making him the youngest US Open Champion ever. 
    The World Junior championship was held in Toronto and William Lombardy took 1st place with a perfect score. Finally, the first women's chess Olympiad was held in Emmen, Netherlands. It was no surprise that the USSR took first place.
 

 
    Ludek Pacjman won the Czech Championship and the theme of the following game for both sides is the advance of the f-Pawn. After the partial blockade of the Q-side it was clear that the K-side was going to be the main theater of battle. Both sides were striving for the advance of their f-Pawn, a tactical motif often seen in the K-Indian. 

A game that I liked (Fritz 17)

[Event "Czech Championship, Prague"] [Site "?"] [Date "1957.??.??"] [Round "?"] [White "Ludek Pachman"] [Black "Jiri Kopriva"] [Result "1-0"] [ECO "E94"] [Annotator "Stockfish 16"] [PlyCount "77"] [EventDate "1957.??.??"] {E94: King's Indian Defense} 1. d4 Nf6 2. c4 g6 3.

Bf1 {An odd looking move, but white anticipates the possibility of playing d4-d5 and ...cxd5 after which he will recapture cxd5 and black can then play ...Nc5 attacking the e-Pawn. So, white chooses to overprotect his e-Pawn now.} Bg4 10. d5 c5 {Not the best. Closing the center allows white to exploit the position of black's B on g4. 10...Nbd7 was good.} 11. h3 Bd7 12. a3 (12. g3 Ne8 13. a3 Na6 14. Ra2 Kh8 15. b3 f5 16. Bg2 Nac7 17. a4 {is equal.

Here both sides must strive to advance their f-Pawn. However, for black it is very difficult to force its advance.} h6 {Part of black's plan to play ..f5} 16. Nh4 Kh7 17. Kh2 Ng8 {Black has cleared to way for his f-Pawn, but as will be seen, he cannot yet play it. For his part, Pachman thought for him 18.f4 would be premature.} 18. Bd3 (18. f4 exf4 19. Bxf4 Be5 20. Nf3 f6 {White is better, but black's position is quite solid.} ) 18... f6 {With this move black makes it considerably easier for white to carry out the advance f4. Black's best try was to hunker down and play the N maneuver ...Nc7-e8-f3 and hope to defend.} (18... f5 {is tactically faulty.} 19. Nxg6 Kxg6 20. exf5+ Bxf5 21. Qg4+ Kh7 22. Bxf5+ Kh8 23.

The idea is that after the continuation in the game white's B comes into play and the position of the black K will become untenable in spite of the extra Pawn.} (27.

Qh3 Qg6 31. Bh5 Qg7 { White should win this, but he is going to have to bring the N into play with Nd1-e3 etc. and figure out a way to break through.}) 27... Kh7 28. Bg4 Nc7 { Now the other N rushes to the defense of the K, but thanks to the excellent coordination of all his pieces white has no difficulty in building up his attack on the open h-file.} 29. Bf5+ {Vindicating his 27th move.} Kh8 30. Qh5 Ne8 31. Rh2 (31. Bxg5 Nef6 32. Qh4 Qe7 33.
