I tried this out on Rebel 10c and CM6000 and both are totally in the dark.
However when I modify the initial position by removing white's b2 pawn
Rebel finds Qg6 rather quickly. I'm guessing then that it is spooked by the
white pawn majority on the queenside perhaps not having the knowledge that
despite the pawn majority no forced passed pawn can be created for white.

Why do you think Crafty plays Qg6? Is it such pawn majority code or just
searching and extensions? Table bases?
