The trick is not a wider alpha-beta window but to fool beta with some added fixed value that forces a normal cut-off not to be taken, thus oblige the search to go for the next move. The goal is to get a better move-ordering at deeper iterations. You can only do this in the early iterations, say the fisrt 5-7 iterations. I have tried all kind of variations but never found a formula that was clearly superior to Rebel's current move ordering. Still I think there must be something to gain from the idea. Ed
