[Moldovan & Deep Rybka 3]

A90 Dutch Defense Stonewall Variation

1.d4 f5 2.g3 Nf6 3.Bg2 e6 4.Nf3 d5 5.0-0 c6
[5...Bd6 /\6.b3 as in the game 6...0-0 7.Ba3 to trade-off White's bad d.s. B for Black's good one 7...Bxa3 8.Nxa3 Qe7 9.Qc1 b6 10.c4 c5= (Maseda - P. Garcia : Madrid 2009) was more flexible.]

6.b3 Bd6 7.Bb2
[>=7.Ba3 Bxa3 8.Nxa3 Qe7 9.Qc1 0-0 10.c4 transposing into Moldovan - Kativa : Newark Quads 07/26/1987, which continued 10...Ne4N 11.Ne5 Nd7 12.Nd3 avoiding exchanges 12...Kh8 unnecessary 13.f3 Nef6 14.Re1+/= In this opening, White usually plays in the center, with e4, or on the Q-side.]

7...0-0 8.c4 Nbd7 9.Nbd2 Qe8 10.Ne5 Ne4
[>=10...Qh5= ]


[>=11...Nxe5! 12.Nxe4 Nxc4! (12...fxe4?! 13.dxe5+/= Pilz - H. Hess : Berlin 2005) 13.bxc4 fxe4 14.fxe4 dxc4 15.e5 Be7 16.Rxf8+ Bxf8 17.Qc2 b5 18.a4 Ba6 19.Be4 g6 20.axb5 Bxb5 21.h4 L. Smejkal - Bayer : Bayern 1996; 11...Nxd2?! 12.Qxd2+/= Kaes - Weber : Ulm 1995]

This weakens the K-shelter, in general, & the g3 point, in particular. [>=12.Nd3 ]

12...Nf7 13.f4 Nfxe5 14.fxe5 Be7 15.Nf3 Qg6 16.Kh2 f4!
Hitting the enemy's sore spot.

17.gxf4 Rxf4 18.Bc1 Rg4!?
[18...Re4 19.Bg5 Bxg5 20.hxg5 c5 was a good alternative.]


[19...Bxh4 20.Bxg4 Qxg4 , with compesation for the sacked Exchange, was right.]

[20.Rg1 would have given White a clear plus.]

20...Bxg5 21.Nxg5?!
This loses a P. [21.hxg5= was required. As Sturniolo said in the post-mortem, Pawlowski probably overlooked the pin resulting from...]

21...Rxh4 22.Nf3
[22.Nxe6?? loses a piece to 22...Qxe6 and 22.Bxe6+ is illegal.]

[>=22...Rh5=/+ ]

[>=23.Rg1 Qh5 24.Rg3 ]

23...Qh5 24.Ng5 Nf8?
[24...Rg6 25.Rg1 h6 26.Nf3 Nf8=/+ should have been preferred.]

25.Qf4 Ng6??

This leaves the back-rank vulnerable. [25...Bd7+/= was mandatory.]

&, facing mate in 3, Black resigns. [26.Qf7+ Kh8 27.Qf8+ Nxf8 28.Rxf8# ] 1-0
