I finally got RFP to gain! but it might not be as good as it seems…

ive been struggling to get rfp, a pretty basic improvement, to actually do anything, and redid everything search step-by-step to make sure i didn’t do anything wrong. so far, i’ve added back SEE move ordering, butterfly heuristic, PVS, transposition table move ordering, and RFP. however, i don’t think this actually fixes my problem; the code is largely the same aside from some parameter changes, so my theory is that rfp is only working now because i added everything back in a different order, and now i might struggle with adding back different features that aren’t gaining anymore.

i’m currently testing null move pruning (based on the null move observation: doing something is basically always better than doing nothing), and it’s not doing as much as it used to… disturbing
