The game ended in a draw. I don't know at which move I went wrong. I thought I had a winning pawn structure, and after I had pinned the bishop to the king, I thought I would promote by b pawn. But things did not go the way I thought they would, and black threatened mate after sacrificing his rook on h2, so I had to draw the game by repetition.
Thus, I needed to know which move could I have played better to improve my position.
Thank you!
Move reason:
9. Qe2 to add extra defence to e4 pawn in case there is deflection of light squared bishop.
18. c4 Anticipating queen side castle of black and thus starting a pawn storm on that side.
25. f3 adding the much needed protection to both pawns.
32. Ra7 pins the bishop (which attacked the a5 pawn) and allows the queen to be moved freely (which defended the a5 pawn)
35. g3 blocking the dark squared bishop whose position was very threatening after rook sacrifice on c1 and then Qc1.
42. Kh3 so that this: Rxh2, Nxh2, Qxh2# is prevented.
