My modified Crafty 17.10 plays:

12    30.02   5.35   1. h6 Rd6 2. hxg7 Kxg7 3. Rxh7+ Kf6
                     4. Rh5 Ke6 5. Re5+ Kd7 6. Rc5 Ke6 7.
                     Bf5+ Kf6 8. Rc7 Rd4+ 9. Be4

I don't have TBs, so this could really be a drawn KRBKR position.  Can someone
check?

Thanks,
Jeremiah
