Black's move seems to be the most natural in the world, but, after the game, Stockfish 10 preferred 13...Kf7. Can you see why? The reason is covered in the next note.

14.Qg5+ Ke8 15.Qxd8+ 

I made this move quickly, seeing an opportunity to simplify things by getting the Queens off of the board, leading to a position where I would be a pawn up.

Had I looked closer - or been less anxious - I would have found the alternative, 15.Qxg7, which would scoop up another pawn, and leads, after 15...Qf6 16.Qxf6 Nxf6, to an exchange of Queens, anyhow.

Playing against computers makes me nervous. (Against human beings, too.)

15...Kxd8 16.Rxh2

16...Be6 

Instead, 16...Nf6 17. d3 Ng4 18. Rh4 Nf6 19. Be3 Bg4 20. Bd4 Bd1 21. Na3 Be2 22. Kf2 Bxd3 23. cxd3 c5 24.Bxf6+ gxf6 25. Nc4 Ke7 26. Ne3 Kf7 27. Rah1 Kg6 28. Rh6+ Kg7 29. Nf5+ Kg8 30.Rxf6 d5 31. Nh6+ Kg7 32. Rf7+ Kg6 33. e5 Rhg8 34. Rf6+ Kg7 35. Nf5+ Kh8 36.Rxh7+ Kxh7 37. Rh6 checkmate, was Born Loser - NN, 2005.

17.Nc3 g6 18.d4 h5 

The rest of the game, starting with this move, has a bit of an odd tinge to it. Some of Black's moves are hard to fathom. Readers may also be frustrated by my sudden intense caution.

19.d5 Bf7 20.e5 dxe5 21.fxe5 


The central "Jerome pawns" give White a winning advantage.

21...c6 22.d6 

It was better to advance the other center pawn.

22...Bd5+ 23.Nxd5 cxd5 24.Be3 


Safe development, but 24.e6 was stronger.

24...Kc8 25.Rd1 a5 26.Rxd5 Nh6 27.Bxh6 Rxh6 28.Kf3 a4 29.Re2 h4 30.gxh4 Rxh4 


31.e6 Rh3+  32.Kg4 Rh4+ 

Black throws away the Rook, in order to push even a more dire position from appearing on its analysis "horizon". I have seen examples of computers tossing piece after piece, just to make an even-more-unfavorable future position "disappear", only to have it "reappear" after the opponent makes a capture. In the end, more material is lost than in the "dreaded" situation it is trying to avoid. (The similarity to human clinical depression is notable.)  

33.Kxh4 a3 34.d7+ Kc7 35.e7 Rh8+ 36.Kg4 Rh4+ 


See the previous note.

37.Kxh4 g5+ 38.Kxg5 b6 39.d8=Q+ Kb7 40.e8=Q axb2 41.Re7+ Ka6 42.Qa4 checkmate
