Position after 27. g6!?

Klecynski Jr. V Duchamp, Paris, 1924. Alekhine defense, exchange variation (B03)

1. e4 Nf6 2. e5 Nd5 3. c4 White continues along haplessly with the preparation of his pawn center, all under the guise of ‘tempo’. Of course, White has only entered into what is perhaps the most suicidal variation against Black’s defense. …Nb6 Black does not mind the multiple movements of his knight in the opening, the cost for white to inflict this outcome has far outweighed that since taken on by black. 4. d4 d6 The first preparation in Black’s counter attack 5. exd6 exd6 After the great pains white has expended in advancing its forward pawns, he is now left with little more than an ill supported center to show for his efforts! 6. Nc3 It is of course much to late to reverse the damage imparted unto white in its overly ambitious forward movements, but this development of a minor piece helps to delay the inevitable Be7 7. Be3 O-O Black’s position is now beyond immediate defeat 8. Bd3 N8d7 9. Nf3 Nf6 10. Qc2 h6 Forced, to mute the classical central battery of bishop and queen against the black king 11. O-O-O A bold, yet damning, gamble, as will be noted later. Better was O-O. …Be6 Black completes his development with tempo, bringing a striking blow to bear against the romantic center of white 12. b3 a5 13. d5 Further optimism from white!  …Bd7 14. Bxb6 The threat of doubled pawns does not bother black in this position, the potential attacking opportunities on the queenside castle are compensation enough cxb6 15. a4 Rc8 16. Kb1 Kh8 17. h3 Ne8 18. Nd4 Nc7 The spring is loaded 19. f4 Thoughtless endeavors into no mans land. …Bf6 20. Nf5 Be8 21. Ne4 Nxd5! A brilliant punishment against the pinned c pawn! 22. Nfxd6 Inadequate compensation …Ne3 23. Qe2 Nxd1 24. Rxd1 Nxc8 would be followed by Qd4, threatening a mate in two should white play Rxd1 or Qxd1. If white ignores this obvious trap, the position still remains open to any number of militant incursions on the part of black, such as 24…Qd4 25. Nd6 Qa1+ 26. Kc2 Bd4  …Rc6 25. Bc2 Qe7 26. Qh5? An overestimation of attacking vigor- white will not be able to substantiate its whimsical desires on the king side. Better was Qd3 …Bd7 27. g4 g6!? A daring sacrifice is thus offered to white, forcing the question of whether or not he wishes to push his attack to its limits. The dilemma of potential overextension seen throughout the daring of white’s attacking plan is thus put to the ultimate test of praxis. 27…Bc3 was better for black in terms of maintaining an equal balance of pressure and king safety, though this would have in turn blocked the counter-play found in the game continuation for black. 28. Qxh6+ Kg8 29. Nxf6+ Qxf6 A forced return of the exchange for a piece and a pawn, but one which allows black the opportunity to prepare his final thesis against the poor king safety set in place by white’s fanciful long castling 30. Ne4 Qe7 31. g5?? Better was likely 31. f5, a move which would have justified the earlier advance of the f pawn, while both furthering white’s attack and shoring up key routes to his king. After this advance, black is forced to take with …gxf5, as failure to do so leads invariably to a queen and pawn mating net. While white’s attack was not initially bound for victory, correct play in this position would have exploited the questionable artistry of black’s earlier pawn sacrifice with 27…g6 …Bf5 32. Nf6+ Rxf6 33. gxf6 Qxf6 34. Bxf5? A desperate move for a desperate scenario- better was to offer the exchange of queens with the potentially simplifying Qg5 …Qxf5+ 35. Kb2 Re8 A fine acquisition for Black’s final assault, and one which seems to pull black solidly out of the fire. 36. Rd2?? Equalization could still have been pulled out of white’s position with Qh4, the final opportunity which would be found for white in the game. Qf6+! 37. Kc2 Re3 Necessary preliminaries 38. Qg5 Qc3+ 39. Kd1 Qa1+ 0-1
