Nc3 c6 4. Nf3 Nf6 5. e3 Bd6 6. Bd3 b6 7. O-O Nbd7 8. e4 dxe4 9. Nxe4 Nxe4 10. Bxe4 Bb7 11. Bg5 f6?! 12. Bh4 O-O 13. Qc2 h6 14. Rfe1 Re8 15. Rad1 Nf8 16. c5! { Black has played an unnecessarily weakening move with 11. ... f6?!, and now has a hopelessly passive kingside. White has additionally shut out Black's light-squared bishop with this thematic move, and should be in firm control. } 16... Bc7 17. cxb6?! { If Hebbar is already this strong despite giving up positional binds to go after loose pawns, imagine how strong he will be once he develops appreciation of the squeeze. } (17. Nd2! { After pushing c4-c5, why not go to the c4-square with the knight, then play Bh4-g3 and start moving in to the roomy condo on Black's d6-square. }) 17... axb6 18. b4 (18. Bxc6 Bxc6 19. Qxc6 Rxa2 { Maybe White missed that Black would regain the pawn when playing 17. cxb6?!. That would also explain why they chose not to go for this line, which still offers good chances for White after } 20. d5! { . Black is fine after } 20... Qd7 21. Qxd7 Nxd7 22. Rxe6 Rxe6 23. dxe6 Nc5 24. Nd4 Be5 25. e7 Kf7 26. Nf5 g6 { but there were many ways for Black to go wrong in this long variation. }) 18... Rc8 19. b5?! { Again, White gets fixated on a tactical idea that looks like it can net a pawn, but misses his opponent's resource. } 19... cxb5! 20. Qb1 (20. Bxb7?? { was the intention, but } 20... Bxh2+ { was the refutation. }) 20... Bxe4 21. Rxe4 Qd5 22. Rde1?? { I understand why White would want to keep the rook "active" in the center, but heavy pieces are easily exposed, and now White loses a bishop thanks to Black's extra tempo on the e4-rook. } 22... f5 23. R4e3 g5 24. Nxg5 (24. Bg3 f4 { is no better. }) 24... hxg5 25. Bxg5 f4 26. Re5 Bxe5 27. Rxe5 Qc4 28. Bxf4 Qc2 29. Rg5+ Kf7 30. Qf1 Red8 31. Be3 Rd5 32. Rg4 Qxa2 33. h4 Qc2 34. Kh2 b4 35. Qa6 b3 36. g3 b2 37. Qa7+ { Excellent resolve from Black! } 37... Rc7 { 0-1 Black wins. } 0-1
