  suenteus po 147: What's up with 14...Kf8? Was it a touch move or is there some big danger in castling? I can't see anything immediately threatening, but maybe that's my problem....
May-22-05  valerianus: <suenteus po 147> Hi suenteus po 147, the problem with outright castling, viz. 14...0-0 is that it fails, i.e.: 14...0-0 15 ♗h6 ♗f6 [but not 15...g6 because of 16...♗xf8] 16 ♘d5 hitting the Queen and the Bishop on f6, which is effectively defenseless because of White's pin on the g7 pawn.

  suenteus po 147: <valerianus> Thank you for the line. This is where I think I don't see enough. I saw all the way up until the knight fork that you talk about, but doesn't 16...Qd6 save the queen while simultaneously protecting the bishop?
May-22-05  piteira8: Perhaps instead of 15. Bh6 white should play 15. a3. If the black queen cannot use the a3-c8 diagonal, then white's attack may be difficult to stop.

  suenteus po 147: <piteira8> That's just simple enough to be genius! That's probably what I was missing when I analyzed the position. Thanks!
May-22-05  Ziggurat: These GMs should really know better than to go pawn-grabbing in the opening! This game, to me, looks like a textbook Morphy game with Jobava playing the part of the hapless victim.

  Honza Cervenka: <suenteus po 147> <but doesn't 16...Qd6 save the queen while simultaneously protecting the bishop?> What about 14...0-0 15.Bh6 Bf6 16.Nd5 Qd6 17.Nxf6+ Qxf6 18.Rd6?
Jun-09-05  sharkbenjamin: I was shocked by 6.Bxe4. Then the pawn sac, then compensation for the pawn sac was enormous. Excellent game.
May-16-06  notyetagm: 18 ♗c5! is an excellent move, exploiting the tactical point that both the Black c8-rook and a5-queen are <OVERWORKED>.

That is, both of these Black heavy pieces are needed to prevent a <back rank mate on d8>. The Black c8-rook cannot leave the 8th rank and Black a5-queen cannot leave the a5-d8 diagonal, both on penalty of mate on the <weak back rank> d8-square.

18 ♗c5! thus exploits the fact that neither the Black c8-rook nor the Black a5-queen actually defends the c5-square. Although this square looks to be defended twice, because of the priority of the <back rank mate threat> it is actually undefended.

18 ♗c5!
18 ... ♕x♗?? <deflection from d8> 19 ♕d8+ ♖x♕ 20 ♖x♖# 18 ... ♖x♗?? <deflection from d8> 19 ♕d8+ ♕x♕ 20 ♖x♕#

May-16-06  notyetagm: 19 ♖d5! forces resignation.

If the Black a5-queen flees from the rook to safety (e.g., 19 ... ♕a6), then she also reduces Black's control of the <weak back rank d8-square>. Black is then mated by the <DISCOVERED DEFLECTION> 20 ♕xe7+! ♖x♕ <deflection from d8> 21 ♖d8#.

May-16-06  notyetagm: Bruzon's 18 ♗c5! is very similar to 19 ♕c4!! from the famous game E Z Adams vs Carlos Torre, 1920, shown below:

In this position, neither the Black c8-rook nor Black b5-queen may capture the White c4-queen because both are needed to defend the <weak back rank e8-square>.

Bruzon's 18 ♗c5!, shown below, is based on this exact same tactical idea, only he offers a bishop instead of his queen to <DEFLECT> one of the Black defenders away from the <weak back rank>.

Apr-12-11  YoungEd: Here's a tactic that I caught; if Black doesn't play 17...♖c8, then 18. b4! either mates or wins the ♕. Deflection!

  FSR: Black's play was a lot Baadur than is typical for him.
