Subject: Remove PvNode dimension from Reductions array
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=22ef36803ed0f1597d8f40731c6e2d3aa01debf2;hp=22ef36803ed0f1597d8f40731c6e2d3aa01debf2

Remove PvNode dimension from Reductions array

This is a functional simplification: if we simply subtract one to Reductions[]
when PvNode is set, we can remove this dimension of the multidimensional array.
I think this saves about 8K of memory.
