[I should have played 15.a4 now or later in order not to give Black the counterplay on the a-file]

This move shows that my opponent wanted to play for a win otherwise he would have just taken on b3 [27...Rxb3 28.Ra1 Kb8 29.Rad1 Kc8 (29...b5 30.Rxd7 Rxd7 31.Rxd7 b4 32.Rxf7 (32.Rd3 Nf4 33.Re3 bxc3 34.Kh2 Kc8 35.Nxc3 Rb4 36.Re4= ) 32...bxc3 33.Rf3 Nd4 34.e6! Nxe6 35.Rxc3= ) 30.Ra1= ]

[We both thought that after 29.R3d2 Black has 29...Ba4? but then (29...Bc6 30.Nc3 Rxd2 31.Rxd2 Ra8 32.Nd5 I have two tempi by comparison with the game) 30.bxa4 Rxb2 31.Nd6+! that was the move we both didn't see during the game]

29...Bc6 30.Rxd8+ Kxd8 31.Nc3 Ra8 32.Rd1+ Ke8 33.Ne2?
[33.h4 was much better]

I was lucky to understand in zeitnot that I have to do this move otherwise I could've just resigned

[Black's idea here is to move his knight to a better position. Unfortunately for Black he doesn't have time to go to the queen side, because I have counterplay on the kingside but Black's knight can go to d4 46...Ne6 47.Kf2 Nd4 (47...Kf8 48.Kg3 Kg8 (48...Nd8 49.f4 Nb7 50.fxg5 hxg5 51.e6 fxe6 52.Bf6 Na5 53.Bxg5= ) 49.Bb2 Nd8 50.f4 Nb7 51.fxg5 hxg5 52.e6 fxe6 53.Bf6 Na5 54.Be7 Bxb3 55.Bxc5 Bc2 56.Bxb4 Nxc4 57.Be7= ; 47...Nd8 48.Ke3 Nb7 49.f4 gxf4+ 50.Kxf4 Na5 51.g5 hxg5+ 52.Kxg5= ) 48.Bxd4 cxd4 49.Nd3 Bxb3 50.Nxb4 c5 51.Na6 Bxc4 52.Nxc5 f6 53.exf6+ Kxf6 Black has better position but White has chances to make a draw.
