2017 CC Spring Open Round 1 Scott Lacy, 1419 - Anton Taylor, 2033 Nimzo-Indian (E41)

2017 CC Spring Open Round 1 
Scott Lacy, 1419 - Anton Taylor, 2033 
Nimzo-Indian (E41)

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 c5 I spent entirely too much time thinking before playing c5. I couldn't remember any of the Nimzo lines in that moment. My two candidates were c5 and the odd looking Nc6 (which I thought was an old sideline recommendation of GM Roman Dzindzichashvili but I couldn't remember any of his analysis so I went with the thematic c5. The correctness of the move in the database is not really relavent as it is pure luck that I made an appropriate room as I got there through a fumbled means. 5. a3 Bxc3+ 6. bxc3 O-O 7. Bd3 Nc6 8. Nf3 d6 9. O-O e5 Black is actually really happy here and has achieved quite a lot.At least equality but optimistically a little more. 10. dxe5? Not at all the right move and probably a bankrupting one. d5, Qc2, and Nd2 are all superior moves. A move I'm surprised hasn't been played much is Be2. 10. ... Nxe5? An inaccuracy that gives white a little more freedom than he would otherwise enjoy. Obviously better is dxe5 when this keeps the knight on the board and threatens e4! 11. Nxe5 dxe5 12. Qc2 Qe7 13. f3 Be6? I thought for a long time before playing Be6 and I really thought about e4! Komodo confirms that this move is just clearly winning. For some reason I could not come to a definitive conclusion and it seems silly now that I did not play the simple temporary sacrifice. 14. e4 Nh5 15. g3 Rad8 16. Be3 Bh3 17. Rf2 Rd7 18. Be2 f5? I was very excited when I played this. I had determined that opening the position benefited me. Komodo thinks this is losing and it is correct but it takes at least ten more moves (20 ply) to prove that point and with the complex branching of the variations it wasn't really possible for me to see that far ahead. 19. f4?? My opponent fails to find that challenge to f5 with the simple exf5 and instead commits a blunder. 19. ... exf4 20. gxf4 Nf6 21. Rf3 Bg4 22. Rg3?? A bad position just got a whole lot worse. 22. ... Nxe4 23. Bxg4 Nxg3 My opponent sees the Bishop is en prise and rather than trying to defend it and play down a rook he throws in the towel. 0-1
