epdpfga with string:
r1b2rk1/2q1bppp/p1npp3/1pnB1N11/4P1P1/2N1B3/PPP1QP1P/2KR2R w - -
in a file. I think I see the problem. The last row described only has 7
squares defined. After adding a 1 to the end, crafty likes Bxc6.
From the PGN Standard:
16.2.3.1: Piece placement data
The first field represents the placement of the pieces on the board. The board
contents are specified starting with the eighth rank and ending with the first
rank. For each rank, the squares are specified from file a to file h. White
pieces are identified by uppercase SAN piece letters ("PNBRQK") and black
pieces are identified by lowercase SAN piece letters ("pnbrqk"). Empty squares
are represented by the digits one through eight; the digit used represents the
count of contiguous empty squares along a rank. A solidus character "/" is
used to separate data of adjacent ranks.
