12...Qc7

• The game is equal.

13.Bf4 Rd8 14.g4

• White's advance on the kingside is a stereotypical plan in Sicilian positions like this.
• 14.h5 h6 15.Qf2 0-0 16.g4 b5 remains equal.

14...b5 15.a3 Qb7 16.Bd3 d5 17.g5?

• In an ultra-sharp opening like the Rauzer, one small slip is all it takes to fall into the abyss. The center is not yet secure, therefore this kingside aggression is unjustified.
• If 17.Qe2 d4 18.Na2 a5 then:
• 19.Be5 19...b4 20.axb4 axb4 remains equal.
• 19.g5?! Nd7 20.h5 e5 gives Black the initiative.

Position after 17.g4g5

17...Nxe4!!

• Black strikes in the center to punish White for his premature attack. The Sacrifice of the Kinght is redeemed by the winning of a pawn.
• 17...b4!? 18.gxf6 bxc3 19.Qxc3 Bxf6 20.Be5 is equal.

18.fxe4 dxe4 19.Nxe4 Bxe4 20.Rh3

• White sees that the pawn is lost and tries to minimize the damage.
• 20.Bxe4 Qxe4 21.Qf2 0-0 22.Rhf1 Rxd1+ 23.Rxd1 leaves Black a pawn to the good.

20...0-0!?

• In a sharp game, one must strike when one can. Removing the King from the center had to wait until now.
• Nevertheless, better is 20...b4 21.a4 b3 22.h5 Bf3 when Black is more active.

21.h5

• White is still intent on a Kingside assault.

21...b4

• With the action in the center complete, Black now counters on the queenside.

22.Be5?!

• White's demise now comes quickly.
• White has a more stubborn defense in 22.axb4! Bxb4 23.Qe2 Rd4 when:
• If 24.Bc1 Qc6 25.h6 g6 26.Bxe4 Rxe4 27.Qf2 Be7, but Black remains a pawn to the good.
• Black is still a pawn to the good after 24.Bxe4 Rxd1+ 25.Qxd1 Qxe4 26.Bc1 Be7, but White has better resources than in the text.

Position after 22.Bf4e5

22...bxa3!

• Black wins a second pawn. White is doomed.

23.b3 Bxd3 24.Rxd3 Rxd3 25.Qxd3 Bxg5

• Still as a consequence of White's feeble 22nd move, Black has won yet a third pawn.

26.Qc3 f6!?

• This is inaccurate, but not enough to endanger the victory.
• If 26...Rc8 then Black wins easily after 27.Qd4 a2+ 28.Ka1 f6 29.Qg4 Kf7.

27.Bg3?!

• White misses an opportunity to present Black with some problems.
• If 27.Bd6 Rc8 28.Bxa3 f5 then:
• 29.Qd3 Qc6 30.Bb2 Rd8 31.Qe2 Rxd1+ 32.Qxd1 Kf7 still leaves Black two pawns up.
• If 29.Qg3 then Black gains a tempo after 29...Qc6! 30.Qd3.

27...Rc8 28.Qa5 f5 29.Be5

• If 29.Qe1 Qc6 30.c4 Qb6 then:
• 31.Kc2 Rd8 32.Rxd8+ Bxd8! 33.Be5 Kf7 34.b4 a2 followed by 35...Be7 is an easy wins for Black
• 31.Qc3 Bf6 32.Qc2 a2+ 33.Qxa2 Rxc4 the end is near.

29...Qe4 30.Rd3 Qh1+ 0-1

• If 31.Ka2 Rxc2+ then:
• 32.Kxa3 Bc1+ 33.Ka4 Qc6+ 34.Kb4 Qb7+ 35.Ka4 Ra2#.
• 32.Bb2 axb2 33.Rd8+ Bxd8 gives Black a prohibitive material edge.
• M. Maze resigns.
