Seirawan Variation 5.Bd3 0-0 6.Nge2 c5 [E70]
An unusual move in what is already an uncommon line is 5.Bd3 0-0 6.Nge2 c5 7.d5 e6 8.Bg5!?:
More normal is 8.0-0 exd5 9.exd5 (while 9.cxd5 is a Modern Benoni). In Moiseenko - Bacrot White now plays a promising exchange sacrifice with 8...h6 9.Bh4 exd5 10.exd5 Nbd7 11.f4 g5 12.Bg3 Ng4 13.0-0!
Sämisch Gambit 6...c5 [E81]
In Shimanov - Jones Black holds on using the Samisch Gambit after 6.Be3 c5 7.dxc5 dxc5 8.Qxd8 Rxd8 9.Bxc5 Nc6 10.Nge2 Nd7 11.Be3 Nde5 12.Nf4 Na5!?:
Black simply attacks the c4-pawn. He had to suffer a lot and was probably lost at some point, but his opening play looks sound.
Sämisch Panno 8...Bd7 [E83]
The Kaufman - Smirin game sees Smirin play his pet line in the Panno 8...Bd7!? His opening is good but then he gets outplayed by his much lower rated opponent. But as we know, the King's Indian is good for swindles...
Classical Variation 6...e5 [E89]
In Rajkovic - Popovic I take a look at the old classical method of play against the Sämisch, 6.Be3 e5 7.Nge2 c6 8.Qd2 Nbd7 9.d5 cxd5 10.cxd5 a6 11.g4 h5 12.g5 Nh7 13.Rg1:
This line has played many times by Karpov. Despite Black's win in the game I think White is looking good theoretically at the moment.
Classical - Makagonov 6.h3 [E90]
In the Makagonov, after 5.Nf3 0-0 6.h3 e5 7.d5 a5 8.Be3 Na6 9.g4 Nd7 10.a3 Nac5:
The move 11.Nd2 was played in Ashwin - Kotronias. This has even been adorned with '?!' but it may be best after all. Instead 11.b4 has been was considered to favour White but now I have my doubts.
Petrosian 7...a5 [E92]
I like games like Bjelobrk - Grischuk. It is usually instructive to see a Super-GM tear apart a lower rated, but capable, master because the mistakes are clearer - wins between two Super-GM's tend to have a lot more subtlety. Following 10.Nd2 Nd7 11.a3 Grischuk avoids repeating the mistakes he made in another game we covered, and here he wins very quickly after 11...f6! in an instructive game.
Exchange Variation 9.Bg5 Nbd7 [E92]
Those who do not study history are doomed to repeat it... In Jakovenko - Paragua we take a survey of the theoretically (but not always practically!) harmless Exchange Variation, 7.dxe5 dxe5 8.Qxd8 Rxd8 9.Bg5 (as well as the more forcing 9.Nd5).
9...Nbd7 I like this line. It is risky strategically but not a bad line to play for a win. However, Black really should not play the 'main line' as he did in this game...
Bayonet Attack 9.b4 Nh5 [E97]
Cori - Radjabov is very peculiar. Radjabov is/was perhaps the biggest Bayonet expert in the world from the black side, but here he plays a line with a bad reputation. He does not have anything new to show and just goes down in flames.
7.0-0 Nc6 8.d5 Ne7 9.b4 Nh5 10.Re1 f5 11.Ng5 Nf4 12.Bxf4 exf4 13.Rc1 is considered to be only a little bit better for White, but the game's 13...h6?! is very hard to understand.
Until next month, David
