I disagree. 1)It is easy to avoid -1 pawn disadvantage by using a small book. It is also easy to get the opponent out of book (for example by lines like 1.c3 and 2.Qc2) 2)Kure and Noomen do not get +1.0 pawn advantage from the opening after every game > >I would expect IBM to lose with 18-2.

I believe that they searched deeper and the output suggest 16-18 plies but I do not believe that 16-18 plies were totally brute force because it seems impossible to me to search 16-18 plies brute force even with their hardware. They probably used futility pruning. > b) their book is hell worse as nowadays books are They only need a small book. Big book may be good only for blitz and when the time control is slower it is better to use a smaller book. Uri
