Alright, I agree...
I am using TWO-DEEP as a replacement scheme.
(move the first two the second entry when new data has a higher draft,
else overwrite second)
Not clearing the hashtable between iteration, just between succeeding searches.
I checked all do_move's and undo_move's by comparing the incremental hashkey
with the fresh-from-scratch generated hashkey before AND after every call,
including NULL-move.
I am using the same random number generator as Crafty is.
I rechecked the values that are used:
Overall:
~50% 0's
~50% 1's
Per bit-position over all 368 keys (P=48, N=64, B=64, R=64, Q=64, K=64)
all have
~50% 0's
~50% 1's
I am desperate for help!
