1. d4 g6 2. e4 Bg7 3. c4 d6 4. Nc3 c5 5. Nge2 {I was trying to transpose into the King's Indian Saemisch variation. Probably better is 5 Nf3 where White obtains a slight advantage, or transposes into a Sicilian variation. I was not interested in playing a Benoni, forced to go into the variation where White plays e4. I did not play Be3 because I was not sure who had the advantage after 5...cxd4 6 Bxd4 Bxd4 7 Qxd4 Nf6, and frankly, I did not see that 8 Nd5! cramps Blacks pieces or disrupts his pawn structure. All I saw was ...Nc6 chases the queen away with tempo. The moral of the story here is when analyzing over-the-board go as deep as you can, and then go deeper. Mike Brooks told me later, "You have got to look at everything, everything!" - mlp} Nc6 6. Be3 Qb6 7. Nd5!? {I spent 25 minutes on this move before I played 7 Nd5. Afterwards, Brooks analyzed it for about an hour. Black cannot play Qb2?, but after 7...Qd8 White's plan falters when Black plays ...Nf6. - mlp} Qa5+ 8. Bd2 Qd8 9. Bc3 e5 10. dxc5 dxc5 11. b4?! {White has better moves. Most importantly, he needs development! - mlp} cxb4?! {This is bad. White cannot take the c-pawn because Black's normal development will overwhelm White in the end. - mlp} 12. Nxb4 Be6 13. Nxc6? {"Black is winning," IM Michael Brooks said. "12 Nd5 is a much better move."} bxc6 14. Qa4 {Don't you had it when you just beat the highest rated player you have ever beaten and some new IM comes along and tells you that you did not play a good game? I was still happy, all the same. Here 14 Qa4 is dubious because White has not completed his development. Black should have sacrificed the c-pawn for development and soon would have crushed White. - mlp} Qb6?! 15. Ba5 Qc5 16. Nc3 Rb8 17. Nd5! Bxd5 18. cxd5 Ne7 19. Rd1 O-O 20. d6 Nc8 21. d7?! {Much better is 21 Be2, 22 O-O and then 23 Nd7. - mlp} Nb6 22. Bxb6 Qxb6? {23...Qc3+ and Black has a clear advantage. - mlp} 23. Ba6! {White offered Black a draw because of the bishops of opposite colors ending, but Black scorned White's offer. - mlp} Rfd8 24. O-O Qc7 25. Bc8 Bf8 26. Rc1 Rb6 27. Rfd1 c5 28. h3 Qb8 29. Qa5 Be7 30. Rc4 Rb4? 31. Rxc5! Rxe4?? 32. Rb5! {The queen has not squares! 32...Qa1 loses to 33 Bb7!. - mlp[} Re1+ {Resigns is the best move here. - mlp} 33. Rxe1 Qd6 34. Rbxe5 {Marty Phillips (1813)-Jeffrey Dahl (2188), 1989 USA Open, 1-0. Black resigns. White is threatening to play Rxe7, if Black moves the Bishop say to f6, then Re8+ forces the black rook to recapture and then Black has to give up more material to keep White from gaining a second queen, i.e., 35...Bf6 37 Re8+ Rxe8 38 Rxe8+ Kg7[] 39 d8=Q Bxd8 40 Qxd8. Black is a rook & bishop down and White is threatening to trade off the queens or simply form a mating net. - mlp} 1-0
