2017 On The Move Round 4
Anton Taylor, 2027 - CM Jerry Baker, 2035
Nimzo-Larsen: Indian (A01)

1. b3 Nf6 2. Bb2 e6 3. c4 d5 4. e3 c5 5. Nf3 Nc6 6. d4 cxd4 7. Nxd4 Bb4+ 8. Bc3 O-O The more common move here is Qa5 but this is not bad and is the second best and a consistent and solid approach. 9. Bxb4 Nxb4 10. Be2? a3 was necessary to keep control of c2. 10. ... e5 11. Nf3?? Nc2 is met by a5 but is still probably necessary. 11. ... Bf5 12. O-O Nc2 13. Nbd2 Nxa1 14. Qxa1 e4 15. Nd4 Be6 16. Qb2 Rd1 is better trying to fight for the center. 16. ... Qd6 17. h3 Qe5? Rac8 to further the central grip is better. White is still winning but it's a little harder. 18. c5 Nd7 19. Rc1 f5 20. g3 Rf6? This brings things to a halt. It doesn't continue the attack and it makes the knight a bit worse. g5 makes more sense to roll on with the attack started by investing in f5 and black should have an advantage. 21. c6 bxc6 22. Rxc6 Rg6? Putting a useless sacrifice in the air that was the plan when I played Rf6 but again g5 is the way to roll with the kingside attack. 23. Qa3?? This allows a variation similar to the following: 23... Rxg3+ 24. fxg3 Qxg3+ 25. Kh1 Qxh3+ 26. Kg1 Qxe3+ 27. Kf1 Qxd4 28. Rxe6 Qxd2 29. Qe7 Rc8 30. Qxd7 Rc1+ 31. Kf2 Qd4+ 32. Kg2 Qg1+ 33. Kh3 Qe3+ 34. Kh2 Qf2+ 35. Kh3 Rh1# 23. Bf7 I miss that the rook sacrifice works there but this should still be winning. 24. Bb5 Nf6 Once again Rxg3 is the winning idea. 25. Qa6?? the queen remains far away from the king and while it looks potentially good it is just shuffling around. The problem is that now I have just run out of time to calculate the sacrifice. 25. ... Rxg3+ Now the sacrifice is too late and probably losing ... one possible better course might be 25... f4 26. Nf1 fxe3 27. fxe3 Rxg3+ 28. Nxg3 Qxg3+ 29. Kf1 Qxh3+ 30. Ke2 Be8 31. Rc2 Ng4 32. Rc3 Qg2+ 33. Kd1 Qg1+ 34. Kd2 h5 and the two extra pawns win in the end. 26. fxg3 Qxg3+ 27. Kf1 Qxh3+ 28. Ke1 Qxe3+ 29. Ne2 d4?? the last recorded move is the big blunder in the ending in time trouble. h5, h6, or Kh8 hides the "bear in the hole" and is the winning method that I could not find. In short, the error in the final position is that I did not sniff the danger developing against my king, specifically the white grip on the e8 square was underestimated. 1-0
