If you do the same thing both ways, the results are consistent. Of course, if you do things inconsistently, then you get wrong answers. I simply try to avoid that. But again, you didn't _read_ what I wrote. I _specifically_ said "in the q-search". You didn't read that part, did you? Of course you didn't. But, to make the point, in the q-search you _already_ have "zero plies remaining". So replace all your 4/5 numbers with 0 and then tell me that one is better than the other. Then feel free to apologize for once again popping off without _any_ idea of what you are popping off about, where you are popping off about it, or even why you are popping off. >B) >Re5+ (5 ply remaining) >Kf7 (4 ply remaining) >Rxa5 (4 ply remaining) > What does >If you can answer that question then you'll know the answer to the basic tree >searching question. The answer is above. There is _no_ difference. Because in the q-search there is no "5 ply remaining". Ever think or read before you write??? ---------------------------quote on--------------------------------------- >>There isn't a big difference if you are only talking about the q-search. ---------------------------quote off-------------------------------------- _now_ as far as who knows more about "tree math" I'll take my own knowledge _any_ day. It isn't full of holes, bad assumptions, and misconceptions. Not to mention the total inability to read anything and understand it... > >Best regards, >Vincent
