That leads nowhere, because of the counter argument: it is all about getting the best out of your data structure, everything has some weaknesses and some strengths. Therefore any technical detail will not be a very good measure of what is the best way overall. The second way is just as lose, but no less correct: do we see bitboarders having a great handicap relative to other datatypes? The answer is no, Crafty is doing fine among the amateurs, in spite of being open source! Now, we can go back and forth saying it's faster or slower, it's just moot, only the final product - the engine, matters. C or C++, bitboards or 0x88, very much same kind of debate IMO. -S. >MvH Dan Andersson
