[D]k1/2rbp1pp/1p3p1r/p2P1P2/P1P1B1P1/1P2R2P/5NK1 b - - 0 121
[D]n3/2rr1q1k/1p1p1p1p/p1p1pPpP/4P2N/P1PP2Q1/1P3PRK/6R1 b - - 0 38

These are to me "stone-wall" positions. I don't know how Crafty use to detect
the "stone wall"... by pawn formation positions or by recognition of particular
moves; maybe both. Pablo use to play Crafty and have not much luck before the
removal of the "stone-wall" detection.
