This month there are a lot of ideas from the computer age, for sure, and two games that almost make the Bayonet Attack look like a forced win for White.

Reversed King's Indian Attack 9.b4 [E61]

Lenderman, A - Shankland, S is a KIA reversed:

This setup Lenderman played is kind of all the rage in the reversed position, but with an extra tempo he gets killed. It would be interesting to compare why he got crushed a tempo up when Black scores well with the same setup, 15.d5?! looks wrong to me.

Fianchetto Variation, Uhlmann's line 7...e5 8.dxe5 dxe5 9.Bg5 [E62]

Lenderman, A - Robson, R featured a little innovation in the line with 9...h6:

9...h6 seems ok, but 14.e4 will need some tests.

Karpov System 4.e4 d6 5.h3 0-0 6.Be3 Nbd7 [E71]

I'm not sure what to say about Sivuk, V - Bernadskiy, V, both sides try to be flexible in this line (here White played g2-g4 rather early).

I think these lines are not easy to play with White, you have to have a universal style and stay alert very early in the game. It can pay off though.

Lesser Averbakh or Karpov Variation 6.Be3 Nc6 [E73]

In Lumachi, G - Vocaturo, D 6...Nc6 is another modern move:

It's interesting but probably not technically good enough. There was a 400 point rating advantage though!

Classical Variation 7...exd4 8.Nxd4 Re8 9.f3 c6 10.Kh1 [E94]

10...d5 is a big idea! In Sakaev, K - Chigaev, M play continued 11.cxd5 cxd5 12.Bg5 Nc6! as recently played by Carlsen:

This may change things theoretically in this line as 10.Kh1 is considered the real test.

Swiercz, D - Robson, R was another 7...exd4 success, but this time with 10...Nbd7 11.Bg5 Qb6:

With the MdP in some trouble, are we headed this way? (Ntirlis seemed to think so in a NIC article earlier this year!)

The Bayonet Attack 9...Nh5 10.c5 f5 11.a4 [E97]

Sakaev,K-Murzin,V features 13.Bxf4!N (Vigorito):

'nuff said.

The Bayonet Attack 9...Nh5 10.Re1 f5 [E97]

Finally, more Bayonet hell for Black in Donchenko, A - Fier, A (Nikoas indicated that 9.b4 is indeed the problem).

From the diagram the game's 11...Nf4 looked miserable (and there was a cool trap on move 15). 11...Nf6 looks natural but White crushes here, too. Maybe 11...a5 is ok if Black reverts to the games quoted in the note.

Until next month, David
