They sure are educational and easy to understand ... for me at least. This is really helpful, since I'm not a strong chess player so am having some difficulties finding the right knowledge to build into my chess program. I like to fiddle with the search, and neglect the eval part :) ... so this is giving me some ideas! Although it's not clear to me whether I should use this, coz I'm not sure (in light of the results) if even the top programs have this knowledge built in! ;) The above position is a different kind of 'animal' though, it's an easy (at least for my program, less than a second :)) forced mate. I knew this one, and remembered that I have (dare I say) an even more entertaining position two moves prior to this one: [D]8/7b/8/8/7p/1pp5/7Q/k1K1N3 w - - 0 1 This is also a forced mate, but a bit deeper than the other one ... enjoy! :) Groetjes, Paul
