I only mistype on letter. 13. Kg1!. Besides of being the Responsible of the Diep Book and I follow that game very carefully. I repeat again: 12. ... c6! is an excellent black move suggested in a recent written book of the Tchigorin Defense. >Nonetheless, you have a point in criticizing 13 Qb3?! At first glance, 13 a3(!) >seems slightly better, when White has the strange looking option of replying to >13...Bxc3 with 14 bxc3!?. The benefit of this move order is that Deep Sjeng's >14...Nd5 doesn't automatically win White's dark-squared Bishop, since it can be >re-routed via Be3-c1, a3-a4, and then Bc1-a3 with some advantage to White. > I must mention you that the "spirit of the position" is not to begin operations in the queen side. The plan for the white position is very clear: White has doubled the pawns in the column f because the correct plan is to double the rooks in the column g. Qb3 is a passive computer move that enable to black attack later. >Of course this is merely a hasty assessment on my part after seeing your illegal >move suggestion. You are correct though that Deep Sjeng seems to have thrown >away some advantage with imprecise play later. > My illegal suggestion was a mistake on my behalf. However, 13. Kh1! is the correct move. Your plan in the queen side is slow and I only see a black attack with your proposed plan. Regards, Arturo Ochoa M. >All the best, > >Stephen
