Geoffrey McAuliffe - Michael Goeller [C53]
KCC Summer Tourney/Kenilworth, NJ 2008
I spent some time analyzing this game after it was played, and thought I'd share my thoughts. A speculative piece sac creates difficulties for my opponent that he is unable to overcome at the board, and just when things start to look bad he calls it a day.
This was Euwe's method of reaching the closed Giuoco lines that usually follow 4...Qe7. The Bishop retreat will have to be played anyway, while 4...Qe7 5.d3!? makes the Queen move look less well placed. White should now go in for the pawn sac 5.d4 Qe7 6.d5 Nd8 7.d6! which is certainly the most challenging for Black to meet.
I was thinking during the game that this move might be a little risky, though it is often correct in these type of positions.
The position now resembles the Marshall Gambit against the Bishop's Opening where White typically wins the e-pawn, though Black has some compensation. Not 9... Qd6? 10. a5! Bxa5 11. Bxd5 Qxd5 12. b4 Bb6 13. c4 Qd8 14. c5
During the game, I thought White should definitely try to win the e-pawn, despite the weakening of his kingside after
I don't think Geoff would have played this if he had considered my next. Best was 11. Nb3! threatening to trap the Bishop, which forces 11... a5 12. Bxf4 exf4 13. d4 and leaves White with a clear structural superiority.
I knew during the game that this probably wasn't technically best, but it looked like it would create a difficult game for White without much risk of losing since I did gain three pawns for the piece. And I always find it hard to resist interesting piece sacs. Better, though,was 11... Be6! 12. Nxe5?! (12. Nf1 Bxc4 13. Bxf4=) 12... Nxh3+!! (12... Nxe5? 13. Rxe5 Nxd3 14. Bxd3 Qxd3 15. a5!) 13. gxh3 Bxf2+! 14. Kxf2 Qh4+ 15. Kg1 (15. Kg2? Bxh3+!) 15... Qg3+ 16. Kh1 Qxh3+ 17. Kg1 Qg3+ 18. Kh1 Nxe5! (18... Qh3+=)
This may actually turn out to be the best defense, though during the game it looked to me like a mistake. Black gets a scary attack and good chances well into the endgame after 13. Kf1 Nxf2 14. Qe2 Qd7! 15. d4 Qh3+! (also interesting are 15... exd4 16. Qxf2 dxc3 17. Qg2 cxd2 18. Bxd2 Nd4 or 15... Ng4!?) 16. Kxf2 exd4 17. Qf1 dxc3+ (17... d3+ 18. Nd4 Qh4+=) 18. Ke2 Nd4+!? (18... Rfe8+ 19. Kd1 Qxf1 20. Rxf1 cxd2 21. Bxd2) 19. Nxd4 Rae8+ 20. Kd1 (20. Ne6!?) 20... Rxe1+ 21. Qxe1 cxd2 22. Qxd2 Rd8 23. Kc2 Rxd4 and the attack goes on and on.
Fritz tells me that most accurate was probably 13... Nf4+! 14. Kf1 Nxd3 (14... Qd7 15. Ng1) 15. Bxd3 Qxd3+ 16. Qe2 Qf5, but I did not see why my move was not the best. I also looked at 13...Qd7 during the game.
Fritz likes White after 14. Qe2 Qd7 15. Ng5! (15. d4 Qh3+! 16. Kxf2 exd4 is analyzed above) 15... h6 (15... Na5!?) 16. Nde4! and Black's attack is at an end. If I had seen this I would have played 13...Nf4+.
White has two better tries which seemed unclear to me during the game:
White will have to give back at least the Exchange after Qg2+ and Ne3+, leaving Black with a winning edge due to his passed pawns on the kingside. My opponent therefore did not see much point in continuing to the bitter end.0-1
