This month he have a rare but rather theoretical Four Pawns Attack, along with several games in the 'Caruana Variation'. I have been playing the Classical King's Indian for both colours for 30+ years (OMG) and never paid any attention to this 7...Bg4 move!

Four Pawns Attack 5...O-O 6 Nf3 c5, 9...Re8 [A69]

Potkin, V - Yuffa, D is a rare Four Pawns, with the rare but dangerous line 12.e6:











It has been played in correspondence, and it's not bad, but Black looks fine with the game's uncommon move 13...Rf8.



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

Petrov, N - Haldorsen, B features 6...Nc6 against Be2/Be3:











It had not occurred to be that this may also occur in the equally trendy h3+Be3 with ...Nc6. White can choose between sharp and simple play on move 8. It all looks a bit better for White, but remains playable - for now.



Classical Makagonov Variation 6.h3 e5 7.d5 Na6 8.Be3 [E90]

I think if Black plays this move order, then 8...Nh5 is a better try in the diagram position:











In the lines with ...a5 (like 7...a5) Black should not rush to play ...Nc5. Wang, J - Iskandarov, M is a nice creative game but both sides make mistakes in time pressure.


Classical Variation 7...Na6 8.Be3 Ng4 9.Bg5 Qe8 10.Re1 [E94]

This old line with 8...Ng4 and 9...Qe8 is looking like a dead end to me, despite Black's victory in Egresi, M - Mihok, O. 10.Re1 is simply a strong move:











Perhaps White's biggest problem is that there are a few pleasant choices and it's hard to decide what to play!


Classical, Donner Variation 6.Nf3 c6 7.0-0 e5 [E75]

I do not believe in this 8...c6 line, although Black does get equality within his grasp in Lysyj, I - Shomoev, A.











White will easily find improvements in the opening stage of the game.


Classical Variation 6...Nbd7 7.0-0 e5 8.Be3 c6 9.d5 c5 [E94]

So, W - Duda, J is not so theoretically important, another look at 11.g4, first played by recently retired GM Rainer Knaak:











However, the new American citizen plays a model game using a space advantage in a heavily blocked position.


Classical Variation 7...Bg4!? [E94]

The Caruana variation! I have basically been playing the Classical King's Indian for both colours for 30+ years (OMG) and never paid any attention to this 7...Bg4 move before:











Fabiano borrows an idea of Dzindzi's (unwittingly or not) and plays a very creative strategic game, try to guess his next, very surprising move here:











Don't miss Wojtaszek, R - Caruana, F!

Instead of Wojtaszek's choice, the 8.d5 of Gunina, V - Vitiugov, N looks the most natural to me:











White must keep an edge here, but Black tends to get a playable game. Perhaps White can challenge Black's concept with an idea I give in the notes. I imagine we'll see some tests soon enough.



Until next month, David
