Has any work been done into giving chess skill grades to the various difficulty levels of any computer chess programs?

Re: A case of carrying on past checkmate

It could be said that capturing the king is something that never gets a chance to happen, rather then something specifically forbidden.

Re: Let's swap pieces instead of wearing out openings

Of the 6 possible arrangements of R N B on the king's side, the official arrangement is the only arrangement where foolsmate (1. f3 e5; 2. g4 Qh4#) works.

A case of carrying on past checkmate
