However, I see you take interest in these books and examine them. I write you to ask your impression of the tournament.obk (so far as you have looked). Also what do you think about adding support so Chessmaster as Black can also respond to 1.a3, 1.b3, 1.b4, 1.c3, 1.d3, 1.e3, and 1.g4. (i.e. so some will not claim I support fewer than CM8000.obk) This would carry the price of reducing the 1.d4, 1.e4, 1.c4, and 1.Nf3 variations. I would value your commentary and impressions.
