My modified Crafty does both. :)
Here's the last ply of output:

13    49:08   0.16   1. Bxf5 Kd8 2. Qh4+ Kc7 3. Bd3 Qxe3+
                     4. Qf2 Qxf2+ 5. Rxf2 Ne5 6. Re1 d6
                     7. Rf4 Re8 8. Ne4 Re7 9. Kh1

Bxf5 was found at 25 minutes with a draw score (repetition).  Previous best move
was Bxc6.  If I make Bxf5, Kd8 is the only move it will make.
