  chancho: 16...bxc5 17.Qh5 (the f6 pawn cannot move without leaving the black Queen enprise) 16...Qxc5 17.Qh5 is no better.

  fredthebear: In the final position, if Black accepts the rook sacrifice, 17.Qh4 will mate in one.

The real spark is 14.BxNf6 offering up the queens. This bishop sortie falls under a productive, usually forcing tactical concept of "capture with a threat to capture again." Black was seemingly correct to recapture w/the g-pawn.

What if Black decides to play knight-takes-queen instead of recapturing the White bishop w/the g-pawn? Initially, it looks like the Black knight can make three consecutive piece captures following each of the White bishop's three consecutive piece captures and things come out even. Not so. White interrupts the sequence after two bishop captures. Thus, 14.BxNf6 NxQb3 15.BxQe7 NxRc1 and then comes 16.RxNc1 and Black is down a piece w/his king's rook still en prize while the White rook sits on only open file.

White has just played 11.cxd5. Which one is the best recapture: with pawn, bishop or knight?

Black played 11...exd5 which was good, but maybe 11...Bxd5!? woud have been worthy of consideration. In case of 11...Bxd5 12.b4! would be interesting. If then 12...Bxa2? 13.Qc2 would give White excellent compensation for the pawn.

On the other hand, After 11...Nxd5?! 12.Bd2, White would have the edge.

In general, in this kind of positions White gains nothing by moving his queen to b3, but in this particular position 12.Qb3! was a typical "Marshall swindle". Frank J. Marshall was famous for his clever swindles, and 12.Qb3! was a cunning swindle, inviting Black to play 12...c5, which looks very attractive, but is not as good as it looks.

Oct-08-21  Gaito: Instead of 12...c5?? (falling into the prepared trap), Black ought to have played 12...a5! with roughly an equal game.

But 12...c5 looks so logical and natural that my guess is that many chess players (even masters) would consider that move as their first option. Yet the fact is that after 13.dxc5! Black's game quickly goes down in flames.

At this point Petrov realized that he couldn't capture White's bishop at f6 with his queen on account of the reply 15.Rxc5. (This was the point of Marshall's swindle), so he captured with the pawn, but that proved to be even worse! No better was 14...Nxb3 15.Bxe7 Nxc1 16.Rxc1 Rfc8 17.Rd1 and White would have a winning advantage (two minor pieces for a rook). See diagram below:

Oct-08-21  Gaito: By playing 15...Kh8? Black shortened his agony. 15...Qd7 was the lesser evil, but it would have lost all the same after 16.Rxc5! bxc5 17.Qh4 Rfe8 18.Qxh7+ Kf8 19.Bg6!

Maybe not mate in one, but mate in a few moves:

16...Qxc5 (on 16...bxc5 17.Qh4 wins the queen) 17.Qh4 f5 18.Bxf5 h5 19.Qxh5+ Kg7 20.Qg5+ and mate in two more moves.

  fredthebear: Poor choice of words on my part. "Threatens mate" would have been better.
