Hi In my national chess magazine i found this position [D]r1bqkb1r/3n1ppp/pn1pp3/1p6/3NP1P1/2N1BP2/PPPQ3P/2KR1B1R w kq - It was from the game Alex. Grischuk - Semen Dvoirys, Aeroflot Open 2002 Grischuk played an novelty, and could, according to IM Steffen Pedersen, refute the hole variation. The move played was 11.Ndxb5! It seems to me, that this kind of move is going to be hard for computers to find.
