The proposed solution, the nominated 13...Ng6, leads to a situation where Black's pieces are well coordinated. I've checked it for some hours, but didn't find anything what I really liked for White. - In the chat thread, reply #33, I had given an analysis which included the move 13.Re1 for White. Nevertheless it slowly became clear that 13....Ng6! is strong and should better be avoided. Therefore I'd now recommend another continuation (instead of 13.Re1). This is not to diminish the merits of the nominated 13...Ng6. But if 13...Ng6 is strong, we have to draw our conclusions and search for possible improvements at an earlier moment: 13.h4!?.
In our post when we nominated the move 13...Ng6 we writte:
"Also 13.h4!? does not work now because of 13…Nf5! Also 13…Ng6 14.h5 Ne5 15.Be2 h6 16.Rc1 c5 seems good enough."The idea of the h4 attack was Luzin's and is a typical move that wants to undermine the knight support. It reminds me what Rowson wrote in
Chess for Zebras page 33 when he tells us a story about the game Te. Petersen- Rowson. Torshavn 2000 which was :
1.d4 Nf6 2.Nf3 e6 3.Bg5 h6 4.Bh4 d6 5.Nc3 g5 6.Bg3 Nh5 7.e3 Bg7 8.Nd2 Nxg3 9.hxg3 Nd7 and now white played
10.Qf3?! a6! 11.g4?! d5 12.e4?! O-O 13.O-O-O c5 14.dxc5 d4 etc whith Black coming on top
Rowson writtes :
"In the post mortem we looked at the position before move 10 for a while and decided that if the position proceeded normally Black whould be very comfortable. For instance after ......
Looking at it now, i think we generally overestimated Black's chances if the game proceeds as normal, but what bothered me at the time is that we couldn't see a convincing way for White to develop any ideas and get fully into the game. Tiger Hillarp Persson was watching the post-mortem and he was also perplexed until he hit upon 10.a4!? with the stated aim of "trying to grab some squares" "And he continues to analyse this fantastic idea....
In our case also we thought that if the game continues normally Black will absorve the compensation slowly (please check the wonderfull ...Qf8! idea we discovered at the end of our analysis) and come on top. But as in the Rowson game the h4!-h5 idea (with the aim to grab some squares) seems powerfull to give White maybe enough compensation for equality but again i have to state that it was Luzin's idea and we commented on that with 2 proposals.
