I am not sure why you think this is a problem? Thanks for adding the special situations (1.) and (2.) which I forgot; I think this cases are possible exceptions from a general situation, where a human opponent just can't move in zero seconds. Maybe it's possible at chess servers, when the human player's program has a "premove" function or something - or the player is a blitz expert with a very fast hand. But I was thinking of the fact that a human opponent has at least to make some physical movement normally, which the computer doesn't need to do, and I think this might be unfair (I'm not a blitz player mayself). Btw., in the other "unfairness" discussions I always expressed the opinion that computers play under equal conditions and there is no unfairness at all, but in this case of zero seconds (or 0:00.2 for example, which is more or less the same in this respect) thinking time, I thought this may indeed not be fair. Furthermore, it is known from engine matches that long sequences of moves are "produced" at the end of some games with practically no calculation time, because the programs can neither agree a draw, nor win, nor loose on time. Most of this bad chess could be avoided by a minimum of 1 second per move probably. I may be wrong - just an idea. Regards, M.Scheidl
