Adjust return value in qsearch after fail high Instead of returning strict fail soft fail high return value between value from search and beta (somewhat by analogy to futility pruning and probcut). This seems to be somewhat depth sensitive heuristic which performed much worse at LTC while performing much better at STC if it is more aggressive, passed version is the least aggressive one.
