Don't forget "good hardware". I get a fail high at depth=18, 35 seconds, on the
quad 550 (big hash, etc). score is +1.76:
18 35.99 ++ 1. ... Kf5!!
18 1:06 1.76 1. ... Kf5 2. c4 dxc4 3. d5 Bf1 4.
Bh8 Be2 5. d6 Ke6 6. f4 Bg4 7. Be5
c3 8. Bxc3 Kxd6 9. Kh2 Bf5 10. Ba1
19 plies took 15 more seconds, up to +1.86. 20 was done in just over 2 minutes,
score creeping up slowly iteration by iteration.
This might be found in a blitz game, the search would be faster if it had an
old hash table already primed with data. And thinking on the opponent's time
would likely help too.
