Yes, that's a good suggestion. I will try to do that in the future. There are many examples I can find in the chess literature. It is simply a matter of time to dig them out and post them here. There is one potential problem with doing that, however. As a chess amateur, I may do a poor job of selecting a suitable example. If the position I select has a simple tactical solution, then everybody will show how their engines produced that tactical solution quickly. That would be a complete waste of everybody's time. >things like initiative advantage are too abstract and maybe position when this >is the only advantage may explain better what you mean and what is the >difference between it and space or developement advantage. I am sorry, but since you have excelled in chess in the past, I naturally assumed you knew the differences between these things. How could someone create a good chess engine otherwise? >I do not think that there is a known definition for all the term(a good >definition means that you have an algorithm to calculate if one side has the >advantage My one resource is the chess literature. Unfortunately, the "algorithms" discussed there are for implementation in human brains. That which makes sense as an "algorithm" for the human brain [viewed as a non-sequential computer] may be totally inappropriate for sequential machines such as PCs. >(material or pawn structure are simple to calculate but >I have no idea what exactly you mean in the other things). > >Uri
