Steve Stoyko - Larry D. Evans [A26]
Westfield Master Invitational/Westfield, NJ USA (6) 1974
Steve Stoyko considers this his best game. It was played in a Masters Invitational tournament at the Westfield Chess Club, which featured Mike Valvo, the young John Fedorowicz, Larry D. Evans, Gene Shapiro, David Floreen, and Steve Stoyko. Steve had recently beaten Floreen in the last round of the NJ State championship to win that tournament. Going into the last round here, Steve had three draws and Evans was a half-point ahead. If Steve won he was clear first, if he drew he was out of the money.
To avoid Evans' s favorite Benoni, since White does not need to play d4 right away if at all with the English move order.
A surprise for Steve, who had been preparing for a week. The move was most surprising since it often signals a desire to transpose to the King's Indian Defense, which Evans did not generally play. Black can't get the King's Indian by 1... Nf6 2. g3 g6 3. Bg2 Bg7 4. Nc3
7... Nf5!? 8. Nd5 h6 9.
O-OBe6 10. Nf2 O-O11. e4!? (more thematic is 11. e3 holding all the central squares, but White plans a speedy kingside attack) 11... Nfd4 12. f5!? gxf5 13. Qh5 Kh7 14. Nh3 f6 15. exf5 Bf7 16. Qd1 Rb8 17. g4 Bxd5 18. Bxd5 Ne7 19. g5!-> Nxd5 20. g6+ Kg8 21. cxd5 c6 22. dxc6 bxc6 23. Qh5 Qd7 24. b3 Rb7 25. Bxh6?! premature(>= 25. Rf2!|^) 25... Bxh6 26. Qxh6 Nxf5 27. Qh5 Ne3 28. Rfc1 c5 29. Nf2 Qc6 (29... >= Qf5!=/+) 30. Qh3 Nd5~~ 31. Qe6+?! Kg7 32. Ne4 Nf4 33. Qf5 Qd7 34. Qxd7+ Rxd7 35. Rc2 Kxg6-/+ and Black, a pawn up, went on to win in Watson-Shahade, Marshall CC 1979.
Position after 11...Bd7
Steve notes that this move is "very anti-English -- not an English type move at all. But it's logical since e4 is an outpost square." And the Ne4 encourages f5 which is bad. Now White wants to play fxe5 and Bg5.
Interfering with White's plans. Too loosening is 12... f5 13. Ng5 And Black can't just make any more here: 12... a6?! 13. fxe5 Bxe5 14. Bg5 Bf5 15. Nf6+ Bxf6 (15... Kf8?? 16. Bh6#) 16. Bxf6 and White has a powerful bind.
Defending h6 and keeping an eye on the Bh1 19... Be6!?
Position after 21...Qd8
Position after 27...Bd5 - White forces mate
