When the score drops I'll kill it.\r\nI believe gains might be possible by less pruning with many threads.\r\nCycles used waiting for a spin lock and joining the search in another part of the tree, could in some cases be better spent on pruning less and searching slightly more of the tree. We need some metric for the expected cost of joining versus the expected gain from a pruning operation to be able to implement smarter pruning."}}
