Diagram # till this moment my opponent already spent one hour. She tried to remember my game against Tkachev in Biel but instead made a dubious novelty

[12.Nc3 0-0 13.Bg5 h6 14.Bxf6 Bxf6 15.e5 Be7 16.Nh4 Qe8 17.e6 fxe6 18.Ng6 Qxg6 19.Rxd7 Bc5 20.Rf1 Nd4 21.Qe5 Rf5 22.Qe4 Raf8 23.Rxd4 Bxd4 24.Qxd4 Qg5 25.Bh3 Rd8 26.Qa7 Rff8 27.Qxa6 Rd6 28.Qb7 Qh5 29.Qxc7 Rd2 30.Bxe6+ Kh8 31.a3 Rxb2 32.Nd5 Qg6 33.Nf4 Qf6 34.h4 Re8 35.h5 Rd2 36.Qc6 Red8 37.Ng6+ 1-0, Tkachiev Vladislav 2642 - Kosteniuk Alexandra 2469 , Biel 2003 It (open)]

12...Qe7 13.Nxe5 Nxe5 14.f4 Nd3 15.Nc3 Bc6 16.e5 Nd7
[First I was planning to play 16...Nd5?? but then realised that White can just play 17.Bxd5 Bxd5 18.Nxd5 Qc5+ 19.Ne3 winning]

17.Be3 Bxg2 18.Qxg2 0-0 19.a4 b4 20.Nd5 Qd8 21.b3 c6 22.bxc4 cxd5 23.Qxd5??
Diagram # It was the only moment in the game where I stopped and thought for 15 minutes. First I wanted to play Nb2 but then realised that there are better ideas for me. Funnily enough neither me nor my opponent didn't see the possibility for me to save the knight [23.Rxd3 leads to interesting play. I was planning to play 23...dxc4 24.Rd6 b3! sacrificing the knight but moving my pawns as far as possible. When I was little and just began playing chess I often heard that 2 pawns on the 3th/6th rank are worth a rook. 25.Qd5 (25.Rad1 c3 26.Rxd7 Qc8 27.Rb7 c2 28.Rc1? Qc3 29.Qd2 Qxd2 30.Bxd2 Rab8 31.Rxb8 Rxb8 32.Bc3 Rb4 and Black takes the pawn on a4 and then moves his a-pawn, white has no defence against this plan) 25...b2 26.Rb1 c3 27.Rxd7 Qc8 and Black's better]

[23...N7c5! almost winning the game. After the game I got a lot of questions why I didn't play N7c5, the problem was that I just didn't see this move! 24.Qxc5 (24.Bxc5 Qxd5 25.cxd5 Nxc5 ) 24...Nxc5 25.Rxd8 Rfxd8 26.Bxc5 Rd3 27.Bxb4 Rxg3+ ; 23...Nb2 24.Rd2 Nb6 25.Bxb6 Qxb6+ 26.c5 Qg6 27.Kf2 ]

24.fxe5 Qxd5 25.cxd5 Nxe5 26.Bc5 Rfc8
I offered a draw because after 27. Bb4 Rc2 28. Ra3 Rb8 29. Bd6 Rbb2 30. Be5 Rg2+ I have a perpetual 1/2-1/2
