Quite interesting that Crafty 19.12 compiled by ChessBase and your Crafty appear
to be a bit different in their analysis.  You may have used a newer Crafty
though.  Crafty on my machine (dual Xeon 2.4) finds the move later but with a
higher positive score:

r5k1/1RR2p1p/5Ppb/3pB3/3Pr1P1/4P2P/5QK1/q7 b - - 0 1
