Once again, I define "strange book line" as "any book line crafty will not play on its own." I do not see why that is so hard to understand, but apparently it is. Strange or oddball doesn't necessarily mean openings like 1. f3 and 2. Kf2. Strange can easily mean 1. e4 c5 if the program will not play 1. ... c5 on its own, but is forced to by a poorly tuned book (poorly tuned for that particular opening since the program doesn't prefer such a line.) What such matches proves, I have no idea. But it absolutely doesn't prove much about the overall strength of the engine. Perhaps is says something about the engine's versatility in handling every type of opening, but who cares when the engine is not going to play such openings. For example, would anyone really care when two track stars run the 100M dash in a contest, when one of them only competes in the 5000M race? The 100M dash won't mean a thing except for the one that actually runs the 100M race at meets. Yet that is _exactly_ what you are doing. Forcing one of the players to compete in something it won't normally be doing. > There are lots and lots of testers using the same method i >use, based on messages in the forum. Fine.
