Base: Bugfix: move index vs main:
Use span of visited moves to avoid incrementing history of illegal moves vs previous one:
Penalize only quiet moves vs previous one:
Penalize captures that didn't produce a cutoff
[WIP]
Combine previous captures penalty when the move that fails hard is a capture and previous quiet moves penalty when the move that fails hard is a quiet move
[WIP], but not improving just quiet moves
