Retire RootNode template There is no reason to compile 3 different copies of search(). PV nodes are on the cold path, and PvNode is a template parameter, so there is no cost in computing: const bool RootNode = PvNode && (ss-1)->ply == 0; And this simplifies code a tiny bit as well. Speed impact is negligible on my machine (i7-3770k, linux 4.2, gcc 5.2): nps +/- test 2378605 3118 master 2383128 2793 diff -4523 2746 Bench: 7751425 No functional change. Resolves #568
