I think in this position it is very impoprtant. My program without checks in qsearch is slow as turtle in honey. In other words without it this positions are impossible to solve by Armageddon. Checks in qsearch are vey important. I don't know why people not use it in qsearch. Program with it can be slow of course but I not use it always. I use it always in lines where are many checks, because there are important. This formula is only a little slower than qsearch without checks.
