I recently played a not-so-good tournament, my US rating is a little under 1900, and this is a game where I had a draw against a 1600 player that reminds me of how I played when I was 1700. My opponent showed up 45 minutes late and unfortunately I let that get to me psychologically, and started having a bit of an impatient attitude while playing. This caused me to make some positional mistakes that I shouldn't have been making. So I have a few questions in the game PGN, if you guys could answer those and point out anything else that's important, I'd appreciate it. Thanks!

1. c4 e6 2. g3 f5 3. Bg2 Nf6 4. Nc3 Be7 5. Nf3 d6 6. d4 O-O 7. O-O c6 8. d5!? { I thought I could take advantage of black's slow development, but I ended up shutting in my bishop eventually. Should I be more patient and play something like 8.Qc2? I think 8.d5 could work if I follow up well. } (8. Qc2) 8... e5 9. Qb3? { Played quickly and impatiently. This move allows black to close the center, allowing me to shut in my bishop. Would 9.c5 be the best try? } (9. c5) 9... c5 10. e4 (10. Bh3 { Maybe if I followed this move with e4, I could try to trade my bad bishop, but is that really worth it with the weakening of my light squares? }) 10... Nxe4 11. Nxe4 fxe4 12. Nd2 e3 13. Qxe3 Bg5 14. Qc3 Bxd2 15. Bxd2 Qf6 16. b4 { Doesn't seem like this really accomplished anything. Maybe 16.f4 straight away? } (16. f4) 16... b6 17. a4 Na6 18. bxc5?! { It seems to me that this really helped black with his central influence. 18.b5 seems more limiting, and then I could follow with a5. } (18. b5 Nc7 19. a5) 18... Nxc5 19. a5 Bf5 20. f4 exf4 21. Qxf6 Rxf6 22. Bc3 Rff8 23. Rxf4 Bd3 { The after-effects of not playing 9.c5 start to show more. } 24. Rxf8+ Rxf8 25. axb6 axb6 26. Ra7 Rf7 27. Ra8+ Rf8 28. Rxf8+ { In hindsight, I should have realized how bad this ending is for me and repeated rook moves. } (28. Ra7) 28... Kxf8 29. Bf1 Be4 30. Kf2 Bxd5 31. Bxg7+ Kxg7 32. cxd5 Kf6 33. Bc4 { Bishop in front of the pawn (on c6) is probably a more solid setup. } 33... Ke5 34. Ke3 Nd7 { Already having trouble defending my central pawn. } 35. g4 Nf6 36. g5 Ng4+ 37. Kf3 Kf5 38. Bd3+ Kxg5 39. Bxh7 Nxh2+ 40. Ke4 Ng4 41. Kd4 Kf4 42. Bd3 Ne5 43. Bb5 Nf3+ 44. Kc4 Ke5 45. Bc6 { Seems like I'm safe now. } 45... Nd4 46. Kb4 Ke4 47. Bb7 Nc2+ 48. Kb5 Ne3 49. Kc6 Nc4 50. Kb5 Kd4 51. Bc6 Ne3 52. Kxb6 Nxd5+ 53. Kb5 Nc3+ 54. Kb6 Kc4 { My opponent wants to stubbornly play out this drawn ending, so the rest of these moves aren't too important. } 55. Bh1 Kd4 56. Bg2 Ne4 57. Bf1 d5 58.
