Another discussion on checkmates can be found on the Bison Comments Page. Starting with a forced mate in six I found by shuffling pieces around on an 8x8 board - ending with H. G. Muller's computer analysis: K + B always force mate on boards up to 14x14, but usually fail on a 16x16 board.
There may be some forced checkmates that involve a Bison leaping over one of the Kings, but I assume that a Falcon can still force checkmate, possibly taking a few moves longer.
