Reshevsky Plays the Old Switcheroo

 
     Yugoslav GM Svetozar Gligoric started the year 1952 with a first place finish at Hastings. Then came tie for places 3-5 (with Erich Eliskases and Larry Evans behind Samuel Reshevsky and Miguel Najdorf at Havana. His next event was a first place finish in Hollywood ahead of Arturo Pomar. 
     After giving a ten board simul in Los Angeles it was time to return home and on the wat back he stopped in New York to play a match against Reshevsky. After the match it was on to the Olympiad in Helsinki and then he participated in the Interzonal in Stockholm. His final tournament that yer was the Yugoslav championship. 
     Played in New York from June 2-22, according to Chess metrics estimated rating Gligoric went into the match rated 2705 placing his at number 11 in the world. Reshevsky’s estimated rating was number 1 in the world with a 2777 rating. He was followed by Vassily Smyslov (2766) and Paul Keres (2758). 
     For his part, in 1952, Reshevsky had run over Miguel Najdorf in a, 18-game match that was unofficially called "The Match for the Championship of the Free World.” The games were played in New York, Mexico City and San Salvador. Reshevsky scored a crushing victory, winning 8, losing 4 and drawing 6. 
     The Gligoric-Reshevsky match was arranged rather suddenly in order to take advantage of the presence of Gligoric in New York after Reshevsky had returned from his match with Najdorf. 
     In his match against Najdorf, Reshevsky started off with a +6 -0 =2. Gligoric fared a little better...Reshevsky started off with a +2 -0 =4. 
     The first game in the match is an instructive example of switching the attack from one side of the board to the other. 
 

     The mark of great players is their flexibility and their readiness to switch objectives the moment opportunity presents itself. In Chess Fundamentals Capablanca wrote, “...at times the way to win consists in attacking first on one side, then, granted greater mobility of the pieces, to transfer the attack quickly from one side to the other, breaking through before your opponent has been able to bring up sufficient forces to withstand the attack.” 
     In this game Gligoric played the King’s Indian, a defense which is usually played with the idea of starting a counterattack. But, instead, in this game he abstained from aggressive play and only tried hold his own. His strategy proved to be safe, but his defense turned out to be overly cautious and when the position became partly open Reshevsky seized this opportunity to switch his forces to the King-side. He then obtained a strong attack which Gligoric was unable to defend against. 
     It's true, the game is not perfect because in the midst of the attack both players missed better opportunities. The game shows that defending is a lot harder than attacking and the consequences of a slip by the attacker are usually far less serious that a slip by the defender. 

A game that I liked (Fritz 17)

By 7.d5 closing the center, a positional, maneuvering game results where white will likely be attacking on the Q-side and black on the K-side. Reshevsky's 7.O-O is neutral, reserving all the options and leaving black to make the exchange if he wishes.} 7. O-O Nbd7 8. Re1 c6 9. Bf1 {How do you explain this retreat? White played 6.Be2 in order to get castled, but after 8.Re1 returning the B to f1 unmasks the R so it has effect on the e-file. Additionally, the B is not badly place on f1 from where it serves both for defense and for supporting the coming Q-side P advance.} Re8 {The threat is to play 10...exd4 with the hope of making use of the r file.} 10. d5 {After this push black can exchange Ps, but then white would be able to make good use of the c- file.

It's then up to white to decide how he wants to break through.} c5 11. a3 Rf8 { A mysterious looking move, but this Rs return to f8 has a pirpose...it foreshadows K-side expansion by ...f5 after black plays ...Ne8.

Kg2 h6 {This move gas been wrongly criticized as being a superfluous precaution that ruins black's game, but that's an overstatement; black's game is perfectly OK. What Gligoric's problem is that he has been paying too passively. 28...Nb6 was also a good move.} 29. Qa5 Nb6 30. Nxb6 axb6 31. Qc3 {This position is equal, but Reshevsky is quietly preparing to switch operations to the K-side.

Old annotators often praised moves based on the success of the winner and that's why you cannot trust a lot of analysis in old books and madazines. Of course they didm't have engines so they often missed a lot. Of this move it was written that it was "a superficially brilliant sacrifice which forces the final entry' and "it probably needed very little calculation." Another annotator gave it a "!!" and wrote, "A neat sacrifice which makes white's sudden attack irresistible." On the other hand, Stockfish slapped a "?" on it.} (38.
