A Brilliancy By S.S. Cohen

     In 1937, television publicly debuted in America at the New York World’s Fair and it was also the year that the photocopier was invented. 
     In other firsts the cartoon character Daffy Duck was introduced and the world’s first shopping cart was used at Humpty Dumpty supermarket in Oklahoma City. 
     The most famous person in the country was probably Shirley Temple (1928-2014), an actress, singer, dancer and later in life, a diplomat. She was Hollywood's number-one box-office draw as a child actress from 1934 to 1938. Later, she was named United States Ambassador to Ghana and Czechoslovakia.
     The year ended with the 1937-38 Manhattan Chess Club Championship. It did not require a great prophet to foretell the victory of one of America's premier players, Isaac Kashdan who retained the title he had won the year before. 
     The three candidates for the honor, Robert Willman, S. S. Cohen and Dr. Jose[h Platz, entered the last round tied, but Willman won, Cohen drew and Platz lost thereby avoiding any ties. 
 
 
     The following game was played in the championship and Cohen's tactical victory over Platz earned him the brilliancy prize. S. S. Cohen was a strong New York player in the 1930s and 1940s. He was managing editor of Chess Review magazine. 
     Dr. Joseph Platz (1905-1981), a medical doctor, was born in Germany and by the age of sixteen he was considered one of the strongest players in Cologne. After Hitler took power in 1933, Platz emigrated to the United States, where he studied under Emanuel Lasker and remained active in local tournaments in New York and Connecticut for many years. He wrote the book that was published in 1979 titled Chess Memoirs: The Chess Career of a Physician and Lasker Pupil.

  A game that I liked (Fritz 17)

[Event "Manhattan CC Champ, New Yorl"] [Site "?"] [Date "1937.??.??"] [Round "?"] [White "S.S. Cohen"] [Black "Dr. Joseph Platz"] [Result "1-0"] [ECO "C08"] [Annotator "Stockfish 16"] [PlyCount "78"] [EventDate "1937.??.??"] {French Defense, Tarrasch Variation} 1. e4 e6 2. d4 d5 3. Nd2 {Cutting edge stuff at the time as it was a great favorite of the Soviet masters. It differs from 3.Nc3 in that it does not block white's c-Pawn from advancing, which means he can play c3 at some point to support his d4-Pawn. The move also avoids the Winawer Variation (3...Bb4). On the other hand, white's N is on a less active square and on d2 it obstructs his dark-square B and so he will have to spend an extra tempo moving the N before developing the B.} c5 4. exd5 exd5 (4... Qxd5 {Black has three ways of recapturing. 4...Qxd5 is an important alternative, the idea of which is to trade his c- and d-Pawns leaving him with an extra center P. In return white gains time for development by harassing the Q.} 5. Ngf3 cxd4 6. Bc4 Qd6 7. O-O {Theoretically the position is equal, but practically the statistics greatly favor white.}) (4... cxd4 {is unacceptable because after} 5. Bb5+ Bd7 6. dxe6 {white lready has a considerable advantage.} ) 5. dxc5 Bxc5 6. Nb3 Bb6 7. Nf3 Nf6 8. Bb5+ Bd7 {Somewhat better is 8...Nc6} 9. Bxd7+ Nbxd7 (9... Qxd7 10. O-O O-O 11.

The players quickly agreed to a draw.}) (12. a4 a6 13. a5 Ba7 14. Qd2 Qc8 15. Bg3 { is equal. Zapata,K (2197)-Pacheco,M (2362) Lima 2007}) 12... Nc5 13. Nxc5 Bxc5 14.

Be3 Red8 {The doubled Rs on the d-file are not accomplishing anything and this dawdling is almost imperceptibly turning the position to white's advantage.} (20... h6 21. Nf3 Qc6 22. Bxc5 Qxc5 23. Re3 Ree7 24. Rde1 {is perfectly even.}) 21. Re2 h6 22. f3 Ng5 23. Rde1 {Excellent strategy! The open e-file will prove a much greater asset tham any pressure he can put on black's d-Pawn. That said, the position is still equal, but it is black who is on the defensive and so it is he who much watch his step.} Qg6 { The threat is ...Bxd4 and ...Nxf3+} 24. Kf1 Qh5 {Although the text move can hardly be called faulty, it might have proven worthwhile to eliminate white's well placed N with 24...Bxd4} 25. Bxg5 Qxg5 26. Qb5 {Repositioning the Q with a gain of time.} Bb6 {Again, taking the N was a viable alternative.} 27. Qd3 g6 28. g3 h5 {Black is playing for an unjustified K-side attack... unjustified because white controls the only open file (the e-file). Nevertheless, the position is still equal, but very shortly black's plan results in a costly error/} (28... Qf6 {makes is almost impossible for white to make any real progress. For example...} 29. Qe3 Kh7 30. Kg2 Bxd4 31. Qxd4 Qxd4 32. cxd4 { with a drawn position.}) 29. Re5 Qf6 30. Kg2 Bc7 {The benign moves 30...Kg7 or 30...Rc8 would have kept the balance. While hardly a mistake, it indicates that black is barking up the wrong tree in planning a K-side attack.} 31. R5e2 {The move he is going to hit black with in a few moves (Re6) was playable immediately.} (31. Re6 fxe6 32. Rxe6 Qf7 33. Rxg6+ Kh8 34.

White has the initiative, but still can't claim a significant advantage.} a6 {This pointless move costs black time he cannot afford. The safety first move of 32...Kg7 offers him chances at defense.} 33. Qf3 (33. f5 {This shot is very powerful. For example.. .} Rf8 34. Rf1 g5 {Making sure the f-fule stays closed, but...} 35. gxh4 g4 36. h3 {and black's K is going to be badly exposed.}) 33... Kg7 {[%mdl 8192] It's now too late for this to be effective and white now gets a winning attack.} ( 33... Bb6 {and black has nothing to worry about.} 34. Ne6 (34.

Note that black's Q does not have any moves...an indicator that there may be a tactical shot.} 36. Re6 {[%mdl 512] A brilliant end to the game.} fxe6 37. Rxe6 Qf7 38. f5 {[%mdl 32] Black really has no good defense to the threat of Rxg6+ and his R's and B are now nothing more than idle bystanders.} Kf8 39. fxg6 Qg7 {With this move black's flag fell and so he oversteppet the time limit. After the game Cohen demonstrated the win.} (39... Qg7 40. Nf5 Qh8 41. Rxd6 Qe5 42. g7+ Rxg7 43. Rxd8+ Kf7 44. Rd7+ Kf8 45. Qxg7+ Qxg7 46. Nxg7 {mates in 6} a5 47. g4 a4 48. g5 a3 49. g6 axb2 50.
