Hi, Paul!

You found like me with selective in 10 moves. Tim found already in 9.

I hope that you will find soon your hash table bug. Many positions are too slow
for be solvable by brute force without hash. This last position I went only as
far as 7 moves. For 7 moves (no hash) it was already 18 min 55 sec. No chances
for me to go farther.

Salut,
Leonid.
