My litmus test for hashing has always been that if Fine 70 gets Kb1 in a
second or so, you're probably OK, but if you stall out at around ply 18,
you have something horrible going wrong. Fine 70:
8/k/3p/p2P1p/P2P1P/16/K w - - 0 1
The key is Kb1 and you should see a score jump of around a pawn at some
point, and if you get a PV you should eventually see a "Kxf5" in it
somewhere.
Okay, here is my output. Kb1 is found in a second. No stall at ply 18.
Kxf5 appears at ply 19 and persists for a few plys but is not around at
the higher plys (28, 29...)
How's it look to you?
