Well you already seemed to have understood it :) The problem is, that in a typical position you have ~40 moves. Now it is a waste of time to generate all 40 moves, then do move ordering on 40 moves, only to fail high on the first one you search. So, the idea is to generate high probablity cutoff moves and search those first. Not only do you save time in generation but also time on ordering them. With bitboards you get this almost for free, but there are disadvantages. Vincent has of course designed a test that emphasizes the disadvantages. Then he says _I_ have not understood the point, ehmmm. :) >It is unimportant to discuss about subjects that vincent talk about unless he >apologizes about his bad behaviour. He seems harmless to me, like a mosquito bite. ;) -S. >Uri
