Fix incorrect pruning in qsearch Only do countermove based pruning in qsearch if we already have a move with a better score than a TB loss. This patch fixes a bug (started as 843a961) that incorrectly prunes moves if in check, and adds an assert to make sure no wrong mate scores are given in the future. It replaces a no-op moveCount check with a check for bestValue. Initially discussed in #3171 and later in #3199, #3198 and #3210. This PR effectively closes #3171 It also likely fixes #3196 where this causes user visible incorrect TB scores, which probably result from these incorrect mate scores.
