Here is the excerpt from the actual game log, for reference:
White(25): h3 [pondering]
time limit 49.93 (5:49)
nss depth time score variation (11)
12 22.57 -0.46 25. ... g6 26. Qe2 Bb4 27. g4 Qc5 28.
Qc2 Nd2 29. Bxd2 Rxd2 30. Qxc5 Bxc5
31. Rc1 Bd6 32. Rc8+
12 49.35 ++ 25. ... Rd1+!!
12 54.82 -4.05 25. ... Rd1+ 26. Qxd1 Qxf2+ 27. Kh2
Bd6+ 28. Qxd6 Nxd6 29. Bd1 e5 30. b3

(3) 12-> 54.82 -4.05 25. ... Rd1+ 26. Qxd1 Qxf2+ 27. Kh2
Bd6+ 28. Qxd6 Nxd6 29. Bd1 e5 30. b3
Nf5 31. Bf3 Nxe3 32. Bxb7 Qf4+ 33.
g3
The way I allocate time, Crafty would find this with a target time of 24 seconds
as that is when it starts searching that move (Rd1+) at the root, and it won't
give up and move until it gets a score back...
