Tweak check extension condition There are two concepts with this patch: Limit check extensions by using move count. The idea is to limit search explosion. Always extend check if the first move gives check. The idea is to save expensive SEE calls, since the vast majority of first move will have SEE value >= 0, also first move may still be strong even if the SEE is negative.
