Hopefully, work has settled down somewhat and you can get back to the "important" things in life ;) I didn't comment earlier, but Tord's idea seems very good. This will definitely need to be part of the scaffolding I've talked about implementing. I would think a side benefit to this technique would be incremental improvement in your evaluation function as you tuned it to "understand" the nodes that failed. regards, --tom P.S. BTW, congrats on RWBC promotion (and I *really* do mean it) :)
