Crafty likes cxd4 in the above. score = +2.45 after 16 plies...
16 1:54 2.45 1. cxd4 Ke6 2. Re1+ Kd7 3. Re5 Rxd4
4. Ra5 h6 5. Rxa7+ Ke6 6. Kg2 Rd2 7.
b4 f6 8. a4 Rb2 9. Ra6+ Ke5 10. b5

Crafty only sees a draw score here...
21-> 3:30 -0.01 1. ... Ke7 2. f4 Kd7 3. fxe5 Kc6 4.
h5 Kxc5 5. Kd3 Kb6 6. e4 Kc5 7. exd5
Kxd5 8. Kc3 Kc5 9. Kd3 Kd5

This one looks drawish too:
20 3:07 -0.54 1. Qb8 Qa3+ 2. Kh2 Qa2+ 3. Kg1 Qb3
4. Qf8 Qb2 5. Kh1 Qa2 6. Qe8 Qf2 7.
Qb8 Qf3+ 8. Kh2 Qf1 9. Qe8 Qd1 10.
Kh3 Qb3+ 11. Kg2 Qd5+ 12. Kg1 Qd1+
13. Kg2 Qd4

Crafty likes Kd6, but given enough time might go for Qh2. That has risen to
position 2 in the root move list...
17-> 4:57 -1.44 1. ... Kd6 2. Qg2 Rg7 3. f4 Qxf4 4.
Qxg7 Qxe4+ 5. Kg1 Qxd3 6. Qf6+ Kd5
7. Qd8+ Ke4 8. Qh4+ Ke5 9. Qxh5+ Qf5
10. Qxf5+ Kxf5 11. Kf2 Ke4 12. Ke1
d3 13. Kd2 (s=2)
.
