Commit ID 0f6c08c73f516873b312cb8fce0d824a2167b075

Do not skip non-recapture ttMove when in check The qsearch() MovePicker incorrectly skips a non-recapture ttMove when in check (if depth <= DEPTH_QS_RECAPTURES). This is clearly not intended and can cause qsearch() to return a mate score when there is no mate. Introduced in cad300c and 6596f0e, as observed by joergoster in #3171 and #3198. This PR fixes the bug by not skipping the non-recapture ttMove when in check.
