[Event "Holiday Swiss"] [Site "https://lichess.org/study/1GO6STzf/JqVIWaKC"] [Date "2021.12.21"] [Round "4"] [White "Karl Tolentino"] [Black "Will Webster"] [Result "0-1"] [Annotator "Will Webster"] [Variant "Standard"] [ECO "A52"] [Opening "Indian Defense: Budapest Defense, Alekhine Variation"] [Source "https://lichess.org/study/1GO6STzf/JqVIWaKC"] [Orientation "white"] 1. d4 Nf6 2. c4 e5 3. dxe5 Ng4 4. e4 Nxe5 5. Nc3 Nbc6 (5... Bc5) 6. f4 Ng6 7. Be3 Bb4 8. Ne2 d6 9. g3 Bg4 10. Bg2 Bxc3+ 11. bxc3 O-O 12. h3 Bd7 13. c5 dxc5 14. Bxc5 Re8 15. O-O { A fairly reasonable position to achieve out of the opening. White enjoys a space advantage and the bishop pair, but it's not clear how to turn that into gaining material. } 15... b6 16. Bf2 Qe7 17. Qc2 Rad8 18. Rfe1 Na5 19. Nd4 c5 20. Nf5 Qf6 21. Ne3 Bc6 22. Rac1 Qe7 23. Nf5 Qc7 24. c4 { The decisive moment. The c4 pawn is both a major asset - guarding the d5 outpost - and a major liability, since Black's bishop can now target it. } 24... Bb7 25. Ne3 Nc6 26. Nd5 Qb8 { White now has a clear positional edge, though it's still not easy to find a path forward. } 27. Rcd1 h6 28. Qc1 Nf8 29. f5 f6 30. Kh2 Nd7 31. Be3 Nce5 32. Bf4 { White's positional advantage has not gained him anything and now he misses that pinning the knight does not slow the attack on c4. } 32... Ba6 33. Ne3 Qc8 34. Qc3 Nc6 35. Bf1 Nde5 36. Nd5 Qb7 37. Be2 Rf8 38. Rc1 Nd4 (38... Rfe8) 39. Bxe5 fxe5 40. Bh5 Qd7 41. g4 Bb7 42. Qg3 Qd6 43. g5 hxg5 44. Qxg5 Bxd5 45. cxd5 { More simplification, attempting to claim that White's space advantage and passed pawn can't overcome a dark-square blockade. } 45... Qf6 46. Qg4 Qh6 47. Rg1 Rf6 48. Rc3 Rdf8 (48... Rd7) 49. Rcg3 R8f7 50. Bxf7+ Rxf7 51. R1g2 b5 52. h4 a5 53. h5 a4 54. Qg6 (54. Rf2) 54... Qf4 55. h6 (55. Qg4 b4 56. Qxf4 exf4 57. Rg6) 55... Nf3+ { 0-1 White resigns. } 0-1
