A new era of chess >programming maybe - well, almost surely- is beginning. 5 games is way to early to start proclaiming victory. Let's see what happens from here on out. Positional evaluation terms are included in all the good chess engines. I think that Shredder is very good at it. Tactics are also very important. It seems that sacrifices are working. But are you sure that they *are* sacrifices. Perhaps these engines are actually seeing far enough that it is only deep tactics. If the program can see the compensation, it isn't a sacrifice. I doubt if Amir has copied anything that Christophe or Chris have done. After all, he can't see their source code. My guess is that there are lots of brilliant things in Amir's code. Brilliant search, brilliant eval, brilliant tactics, brilliant strategy, brillant opening books. The same can be said of *any* program which has made it to the top of the SSDF list.
