Ok, I've not let it run it completely through till the mate ... but it will take approximately 25 minutes on my trusty old PII 400MHz. That's a pure alpha beta search to 24 ply, no extensions, no nullmove, no mate-find speeding tricks, no nothing :) With just nullmove switched on, that drops to 4'30" until WM12 announcement. So these extensions are really worth a whole lot! Coz with extensions on it only takes <3700 nodes, no time at all. Paul
