prune more nonimproved nodes at low depth
cut more nonimproved nodes at fron at back
cut even a little more non-improved nodes
linear dependence for non-improved eval move count pruning
expand MoveCounts to depth 63 from 31
power 1.5 for non-improved
decrease a little pruning of nonimproving nodes
Decrease pruning of nonimproved nodes a little more gently (previous - 1 )
Couple of more shots at long end of passed stage I patch: very small bump up
