Modified Crafty 18.1 (with SE), PII-300:
21-> 34:34 0.00 1. e7 Rb1+ 2. Kd2 Rb2+ 3. Kd3 Rb3+
4. Kd4 Rb4+ 5. Kd5 Rxb5+ 6. Kxd6 Rb6+
7. Kd5 Rb5+ 8. Kd6 <HT>
22 61:22 0.00 1. e7 Rb1+ 2. Kd2 Rb2+ 3. Kd3 Rb3+
4. Kd4 Rb4+ 5. Kd5 Rxb5+ 6. Kxd6 Rb6+
7. Kd5 Rb5+ 8. Kd6 <HT>
22 91:50 ++ 1. h6!!
22 824:45 1/7? 1. h6
The search seems to have exploded here. I'll let it go until the fail-high is
resolved, just to see what happens.
