My Game

Hello everyone. I am new to the site. I would appreciate some feedback if anyone is willing. This is the first game I've played in a long time. I made an obvious error as black on move 30, and for some reason so was my opponents reply.

1. Nf3 d5 2. g3 Nf6 3. d4 g6 4. Bg2 Bg7 5. O-O O-O 6. c4 c6 7. b3 a5 8. cxd5 cxd5 9. Bf4 Nc6 10. Nc3 Nb4 11. a3 Nc6 12. Na4 Ra6 13. Ra2 Ne4 14. Rc2 b5 15. Nc3 b4 16. Nxe4 dxe4 17. Ne5 Bb7 18.

the diagram

12...Ra6 I think this rook lift was a bit premature.

15...Bf5 might have been better than b4.

17...Nxe4 18. Be3 Nxc3 looks pretty good maybe.

34...a4 35. Rxh6 a3 36. Rh4 Ra6 37. Rd4 a2 38. Rd1 a1=Q 39. Rxa1 Rxa1 and you're looking pretty good.

Thanks for taking the time. How did you get the diagram?

there is a chessboard icon above the submit comment box area where you can insert different types of games/puzzles/etc

did you ever consider playing Be1 at any point? Not that it would have mattered, since this game degenerated into a draw.
