2017 Kentucky Open Round 5 Andy Porter, 2106 - Anton Taylor, 2030 English: Anglo-Indian (A15)

2017 Kentucky Open Round 5
Andy Porter, 2106 - Anton Taylor, 2030
English: Anglo-Indian (A15)

1. c4 Nf6 2. g3 e6 3. Bg2 d5 4. d4 c6 5. Nf3 Nbd7 6. Qc2 Be7 7. O-O O-O 8. Rd1 Even at the GM level this move is fairly common. It makes only a little sense to me. It is just a way to clear the f1 square of the rook. That's pretty much it. There is no hope for this rook to use the d-file. 8. ... Ne4 9. Nfd2? A strange looking move that doesn't really help white extricate the black knight. In fact allowing himself to play f3 makes the knight's journey even more frutiful than it might otherwise be. f3 would be a permanent weakness in the white camp. 9. ... f5 10. f3? A blunder as stated but this was the idea of moving the knight from f3 on the previous move. 10. ... Nef6 Just going back. No need to make the knight awkward by Nd6 even if it is better according to Komodo. Why complicate matters when you're positionally better? 11. c5? This move makes it even easier for black to control d5 and gives black targets on d4 and c5 so his better development gives him something to play for now. 11. ... b6 12. Nb3 bxc5 13. Nxc5?? This further concession gives black a classical center. Black is clearly winning. 13. ... Nxc5 14. dxc5 e5 15. b4 Qc7 There is no need to get complicated just guard everything and white should eventuially collapse. 16. Nd2 a5 17. bxa5 Rxa5 18. Nb3 Ra7 19. e3 Be6 20. Bb2 Nd7 21. Bf1 f4? At the time I felt this move was a lever peeling open the white king's hiding place but  realistically this opens lines for the White bishop pair that needed not be opened. The simple Rfa8 or the powerful (if a bit complicated) Rb8 are much better alternatives. 22. gxf4? exf4 opening the file for the rook and not compromising white's king position is better. 22. ...  exf4 23. e4 dxe4 I felt I was completely winning here and Komodo agrees. However I missed an elementary tactic in a straightforward variation as you will see. 24. Qxe4 Bxb3?? The losing continuation. Nxc5 is really the only move and promises better than equality after something like 24... Nxc5 25. Nxc5 Bxc5+ 26. Kh1 Qf7 27. Qxc6 Be3 25. Qxe7! When I calculated this after dxe4 I thought 25. ... Bxd1 netted the exchange. Unfortunately, with the position on the board I discover to my horror that the bishop capture is met by Qxg7 checkmate! I was mortified. I had just voluntarily given up a piece in a completely winning position. 25. ... Rf7 26. Qe8+ Rf8 27. Qxd7 Qa5 28. Qd2 Bxd1 29. Qxa5 Rxa5 30. Bc4+ Kh8 31. Rxd1 Rxc5 32. Ba3 Rg5+ 33. Kf2 c5 34. Bb2 h5 35. Bc3 Ra8 36. h4 Rg3 37. Be5 Ra3 38. Rd8+ 1-0
