There is absolutely, postively no way on God's green earth that ChessBase is using mini/max to search anything. We would see a branching factor of around 20 and a 15 ply search would take years to finish. I suppose you could consider alpha/beta as a variant of mini/max (but that's like calling Andy Green's "Thrust SSC" a fast bicycle.) Any engine that uses pure mini/max is going to be unfathomably lame. Even engines using pure alpha/beta will get the stuffings stomped out of them by pruning engines. The ChessBase engines do not use mini/max or even pure alpha/beta. Where ever you got your information from was wrong. Even if it was from the ChessBase web site it is wrong. If Amir Ban, Frans Morsch, Mark Uniacke, Christophe Theron, and SMK all came to you personally, promised that they use nothing but mini/max on a written document and signed it with their own blood -- it's still wrong. >So the "Apples & Oranges" now are just the difference between the Top >Commercial Programs and the others. >I find it very intersting that some of the 'lesser' Engines are really >kicking Butt!
