I agree with your assesement, but whenever I tried checks in qsearch, my search blew up. Even if I limited them in all kinds of ways, the branching factor got out of hand. It already is somewhat large, so I couldn't allow it to get bigger. I wonder if you 'try' checks (have a few rules that indicate when it might be worth trying certain moves) or 'filter' checks (have rules when a check is prolly bad) or do something even different. Because I couldn't get it to work in qsearch, I've been trying to make the evaluation catch those blind spots. So far, it helps againt the biggest problems, but still... -- GCP
