One of the things I keep thinking about trying at some point is to strip everything out of GLC (using conditional compiles) so that I can get an exe that doesn't have lots of useless stuff in it (like a nice commandline user interface)... just the stuff needed to actually play chess. I'm sure a few people would then run strings on it too! :) The reason to do this (strip things out) is that I feel this may better on the cache. On the other hand I also feel that this may be better done while implementing a new engine (whose aim is to be more cache friendly anyway), which I have already started, but I haven't done any work on for about 1.5 years! :) This is probably pointless anyway though (the cache friendlyness), because, as you know, speed isn't everything in chess... efficiency is more the thing (e.g. efficiency of knowledge applied). Cheers, Tim.
