19.Qxb5 Rb6 is slighty better for black according to Gelfand(Experts vs. the sicilian, second edition).

I like 10. Bxb5 more. for example game Tal-Stean, Hastings 73 or                     Sibarevic-Bukic, Banja Luka 76. Two beautiful games :)

6. Bg5! has always been one of White's sharpest replies in the Najdorf Variation of the Sicilian Defense.  However, this move is not for whimps!  The game is quite instructive.  It shows exactly what you can expect - very sharp tactical play with endless possibilities in attack - counterattack.  Again, users beware unless you want a real battle on your hands! And I wish people would STOP saying that beginners can even beat GrandMasters with this line -  that's only true if the new player KNOWS  what to do after the initial line of play has been implemented over the board!  If he isn't a student of sharp tactical play and hasn't yet learned how to think 3 or 4 moves ahead to execute combinations - he can forget beating a GrandMaster with this or any other variation! AND THAT IS THE TRUTH!

You could also study the famous Bobotsov - Tal game, in which Tal sacrificed his Queen and Knight for two minor pieces, a Rook and a pawn, and achieved an amazing victory!

So, are there any similar Queen sacrifice games (besides Phobetor's given one, Botvinnik - Smyslov and Bobotsov - Tal) of which you know?

Great game

If you like minor piece/ queen trades, study the game Botvinnik-Smyslov 1954 World Champion match (King's Indian Defence, 0-1).

Great game....Well done Phobetor...

Can somebody show the variations if black played simply 12..exd5?

It would help me a lot,thanks..

Great game.

Those mistakes from Black were costly indeed!

That line is dubious.. See in http://www.queenalice.com/game.php?id=574490

The sacrifice only drawn..12....Qd4? is incorrect but 12....ed5! is the best move, white has to play weel to try drawn only... 

Best regards from Brasil....

I would propose Black to play 12...ed5. Ke8 can escape to the queen side.

Of course, Black situation is not easy but not lost.

Yes, like luis3141 said, 15... Qxb5 is just theory. Among others, Boris Gelfand played it at least once, who has been a 2700+ GM (top 20 of the world) for a long time. So I definetely wouldn't call it a blunder :)

As Phobetor already posted, 15.Qxb5 is theory. I have began playing it with black not long ago, so if anyone wants to prove that white is better send me a challenge. Nice game by the way.

Yeap... nothing impressive... I eat GMs for breakfast

demetrios, then 15... Qc8 16. Bxd7+ Qxd7 (16... Kxd7 17. Nb6+) 17. Nxf6+ wins black's queen for two bishops, which should be winning for white.

Qc8 saves queen and still puts pressure on king. Also his bishop will have to move. 

Thank you for the answer.

Konstantyn, after 18. Qc3+ white wins the rook on h8 so he does have something. After 18... Ke7 19. Bxe6! fxe6 (19... Rg8 20. Rxd6!) 20. Qxh8 white has more than enough compensation for the rook against two bishops. Black's king is not safe and white has a dozen extra pawns.

What if 15...Qa7 instead of the text move?--16.Nf6+Ke717.Bd7 Kf6 and White has nothing. Also 22...Ba6 is an interesting try.Why the GM did not take your Rook on f1? Was he in a time trouble ?

Weeeeeeeell done!
