I would guess the difficulty wasn't with the bishops themselves. Rooks or Knights probably could equally well have been omitted. Reducing the number of pieces (at the outset) by 8, and the number of board squares by 28, drastically reduces the number of legal moves from any position, which in turn reduces the computing power needed to look ahead by a given number of moves.
