Iwer Sonsch: Sure, Black forgot to castle. But the main blunders of this game were made between move 19 and 27, blunders of a kind that you wouldn't exspect from 2700+ players in a classical game (analysis by Stockfish 7). click for larger view
<19.Qh4?> More than 2 pawns worse than 19.Nxf7! Kxf7 20.bxc6 bxc6, where White would have maintained a 0.81 advantage (depth 27). <19...Bxb5?> Black had a great opportunity with 19...Qxg5 20.Qxg5 hxg5 21.bxc6 bxc6 (-1.72 @depth 24). <20.Rfe1?!> 20.Nf3! Qf5 21.Nxb5 Qxb5 22.Bxg7 would have equalized (0.00 @depth 24). <20...Qf5?> After 20...Qxg5! 21.Qxg5 hxg5 22.Nxb5, White would have had nothing (-1.89 @depth 25). <21.Nxb5?!> 21.Nge4! would have again maintained an advantage, and also challenged Black to find the right continuation (21...0-0! 22.Qxe7 Bc6; 0.64 @depth 25). <21...Qxb5?!> Topalov misses a great opportunity to castle: 21...0-0! 22.Nxe6 fxe6 is better for Black (-0.43 @depth 30). <22.Bxg7 Nf5?> After 22...Qxg5 23.Qa4+ Nc6 24.Bxh8, Topalov could have fought on (1.32 @depth 26). <23.Nxe6?> 23.Rxe6+ Ne7 24.Rxe7+ Kxe7 25.Qe4+ Qe5 26.Qxe5# would have ended it quickly. Instead, Karjakin keeps playing on - and the biggest blunders are yet to come. <23...fxe6 24.Rxe6+> 24.Qh5+! Ke7 25.Qg6 Bxf2+! 26.Kxf2 Qb6+ 27.Bd4! (2.91 @depth 26) would have won more clearly than the game line (2.12 @depth 30). <24...Kf7 25.Qf6+ Kg8 26.Bxh8 Bxf2+!?> Losing Topalov decides to sacrifice his bishop for nothing, offering White an advantage of 5.24 (depth 27) rather than 1.53 (depth 27) after 26...Bd4. <27.Kh1??> White had two choices. One wins a piece without any counterattack, whereas the other allows 27...Nxg3! 28.hxg3 Qh5+ 29.Qh4 Qxd1+ 30.Kh2 Qg1+ 31.Kh3 Qh1+ 32.Kg4 Qxh4+ 33.gxh4 Kxh8, when suddenly Black is winning (-2.08 @depth 26):

<27...Qa4??> Black completely misses 27...Nxg3, allowing either mate in nine (starting with 28.Rd8+), or at least an easy victory for Karjakin. <28.Red6 Rf8 29.Qg6+ Kxh8 30.Rd7 1-0> If you ever wanted to play like a grandmaster - Congratulations, you have probably already made it there. |
