How do you decide whether to search checks in qsearch? Im presently tinkering with searching checks: 1) Always (1st ply of qsearch only) 2) If Eval() close to alpha (ie, i don't "need" to capture to get to alpha) 3) If no captures (that bring me to alpha) found I have little data but none of the above have shown much promise so far :( Dan H.
