pn-search on Athlon 1.2ghz:
proved that move e4e5 wins, 9 turns
PN:199372 evals, 6835 expands,  0.98 seconds

pn^2 search same comp:
proved that move e4e5 wins, 9 turns
PN2:1408934 evals, 53176 expands,  7.80 seconds

my current pn2 implementation doesn't work very fast for such
trivial mates, as it is optimized for long searches.
The first 610k evals were done before it got around to even
looking at the move e4e5.
