Nd2 Nc5 10. h4!? { A relatively rare move, but one that has been played by a couple of Indian grandmasters. It can be rather unpleasant for Black to face. } 10... h6 11. Be3 h5 12. f3 Bd7 13. Nb3 Na4 14. Nxa4 Bxa4 15. c5?! (15. Qd3! { followed by queenside castle would have been consistent and rather difficult for Black. The text move opens up the queenside while Black is also able to open the kingside. In other words, things are about to get messy... and when things get like that, my money will always be on Carissa compared to the more solid and strategic Sachdev. }) 15... Nd7 16. cxd6 cxd6 17. Qd2 f5 18. exf5?! (18. Rc1 fxe4 19. fxe4 Nf6 { was a better option for White, but Black most definitely is doing fine at this point. }) 18... gxf5 19.

Bxg7 Kxg7 22. g3 Nc5 23. gxf4 Rxf4 { with a dominating position. Black's king is open, but so is White's and White has more structural problems than a house built on a house facing a mudslide. }) 21. Ra3 f4! 22. Bxg7 Kxg7 { Black now got the position we talked about above, only in an improved version. Black is much better, if not technically winning at this point. } 23. b4 axb4 24.

Qb1 { was keeping Black's advantage somewhat under control. }) 31... Qxh4?? { No! This capture throws away most of Black's advantage. After } (31... Rg7! 32. Qb6 Qg6 33.

Qf7 { , it would be far from obvious how Black would be able to win. }) 32... Kg7?? { Black blunders again, clearly playing too fast trying to take advantage of White's time trouble, something that was completely unnecessary when you are winning on the board. After } (32... Rg8! 33. Qf5 Qf2+ 34. Kh2 Qg3+ 35. Kg1 e2 { , Black wins the game. }) 33. Rc2?? (33. Qc7+! { would transpose to the line mentioned above. Now Black is winning again. }) 33...
