2017 Unc Fraud Round 3 Andy Porter, 2106 - Anton Taylor, 1966 English: Anglo-Indian (A17)

2017 Unc Fraud Round 3
Andy Porter, 2106 - Anton Taylor, 1966
English: Anglo-Indian (A17)

1. c4 Nf6 2. Nc3 e6 3. Nf3 e4 is more energetic but this is fine. 3. ... d5 4. d4 Bb4 5. Bg5 Bxc3+ Here is an inaccuracy. The top level variation in this position is 5. ... h6 6. Bxf6 Qxf6 7. e3. 6. bxc3 c6 better is Ncd7 developing a piece and making the pin awkward for white (because he will either have to trade with anothe knight coming to the f6 square to control the same squares). 7. e3 Qa5 8. Qc2 Ne4 9. Rc1 Nxg5 10. Nxg5 dxc4 11. Ne4 b5 12. Nd6+ Ke7 13. Nxc8+ Rxc8 14. Qxh7 Nd7 Komodo likes Qxa2 but navigating the complications afterward are easier for a computer than a human and it determines the advantage is small enough to not be significant and therefore not justify the pawn grab. Whereas, if white goes grabbing with Qxg7 the open lines for the rooks are very big compensation. 15. Qc2 Rh8? The immediate c5 with the idea of creating a comfortable outpost for the black knight either on d3 or d5 makes a lot more sense. The half-open rook file is not quite as relavent as that central control and black has more pieces ready to join the central fight. 16. Be2 Rh6 this again is "chasing the ghost" of the half-open file and doesn't lead anywhere. It isn't losing but it is wasting dynamic action opportunities in the center. 17. Bf3 Qc7 18. h3 Rah8? This move comes up against a brick wall on h3 that isn't going to crack in a very long time. If white plays 
19. a4 a6 20.axb5 axb5 21. Ra1 I'm certain it is black who will be in a tough spot. 19. Ke2 White for his part throws away a golden opportunity to swing the game in his favor. 19. ... Nb6 20. e4 Na4 21. Qd2 f6? Komodo spots the right move immediately because it is supported by a series of simple tactics. Black should simply admit that Rah8? was a mistake and play Rd8 in which case he still has more dynamic play available in the center and will likely win the battle there because of his more active rooks. 22. Bg4 g5? It's never a good idea to move pawns where your opponent has more pawns. I realized this but I thought that the piece activity I gain on the queenside and the potential open lines would make my rooks better. I did not calculate anything and perhaps that was my real downfall here. Again Rd8 followed by opening the center is the best plan. 23. g3 Qd6 24. f4 gxf4 25. gxf4 c5 26. Rhd1 f5! I felt this move was winning and komodo sees a very big black advantage (+2 for black) but it is a long calculation and my time is ticking away. 27. exf5 exf5 28. Bxf5 Rf6? Stronger is Kf6 when after: 28... Kf6 29. Bg4 Rxh3 30. Bxh3 Rxh3 31. Rh1 Nxc3+ 32. Qxc3 Qe7+ 33. Kd2 Rxc3 34. Kxc3 Qe3+ Black is winning29. Bg4 Rxf4?? and with this final blunder I lose in a time scramble although I am certain my opponent did not find the best replies either after this. The problem with Rxf4 is that it allows Qe3+ when black's pieces become awkward as he tangos around white's central square control. Better is Qxf4 when 29... Qxf4 30. Qxf4 Rxf4 31. dxc5 Nxc5 32. Rd5 Nd3 presents a problem to white ... he either plays something useless like 33. Rb1?? Rxg4 34. hxg4 Nf4+ winning for black or Rg1 and the best he seems to get is a draw by something like 33. Rg1 Kf6 34. Rxb5 Re8+ 35. Kd1 Rf2 36. Bh5 Re4 37. Rg6+ Ke7 38. Rb7+ Kf8 39. Rb8+ Ke7 1-0
