The scoring of 21.b4 seemed a little low considering how bad the move appears to
be (to me, anyway), but then Christophe Theron made an interesting point in
another post about reasons to keep the penalty for trapped pieces lower than
their "objective" value. With that in mind, it appears Crafty understands the
position quite well, and even has Black sacrificing a pawn to tie up both the
queen and the dark square bishop while damaging White's kingside. Further, the
21.Bc1 variation is obviously much better than what happened to Fritz, although
d5 is unavoidably weak, a problem stemming from the opening line rather than Bc1
itself.
