 [White "Damanjeet Singh"][Black "Alex Potts"]1. Nf3 d5 2. b3 Nf6 3. Bb2 Nc6 4. e3 Bg4 5. Be2 Bxf3   {it's tempting for black to get two central pawns, but the bishop pair is stronger overall}   6. Bxf3 e5 7. d3 Be7 8. O-O O-O 9. Nd2 Qd7 10. c4 d4 11. Bxc6 bxc6 12. Nf3 Bc5   {a questionable move - my opponent afterwards said he thought he was getting counterplay on the a7-g1 diagonal, having overlooked 14 exd4}   13. Nxe5 Qd6 14. exd4 Bxd4 15. Bxd4 Qxd4 16. Nf3   {I should have taken the pawn here, but I was worried that my knight might get trapped, and figured it was better to be solidly one pawn up than two pawns up with some risk}   Qb6 17. d4 Rfe8 18. Qd3 c5 19. d5 c6 20. d6   {I understand that black is trying to undouble his pawns, but he should have maintained the tension, this passed pawn is very strong and really restricts black's pieces}   Rad8 21. Rae1 Rxe1 22. Rxe1 Qb8 23. Rd1 Nd7 24. Qe4 Qc8 25. Qf4 Re8 26. Ng5 Nf6 27. h3   {I have a tactical idea which is foiled by my own back-rank, so this renews the threat - but black has time to blockade}   Qd7 28. Rd3   {suboptimal but I didn't get punished for it}   h6 29. Nf3 Re6 30. Ne5 Qe8 31. d7 Qd8 32. Rg3 Kf8   {getting out of the pin but setting up a hidden weakness which will hurt black later}   33. Qf5 Qe7 34. Qxe6!   {there are lots of winning moves here, but this is the winningest - a cute double-deflection of either the queen from d8 or the pawn from g6}   fxe6   {Mahmoud wandered over at this exact moment and thought I was losing}   35. Ng6+ Kf7 36. Nxe7 Kxe7 37. Rxg7+ Kd8 38. Kh2 Nxd7 39. Kg3 a5 40. Kf4 a4 41. Rxd7+   {just so I don't have to worry about hanging a knight fork!}   Kxd7 42. bxa4 1-0
