And since you don't know how good it is, you do the re-search to determine how good it is. Tell me if I'm wrong. Now, a fail low means (as I understand it, tell me if I'm wrong) that not only one score fell below alpha, but that all scores for that node fell below alpha. That means that there isn't a very good move from this node, right? So if every score is a fail low at the current node, you can extend the time to search for this move. Is that how you could use fail lows to your advantage?
