Hi Peter, you shouldn't forget that there are two clocks, cause each program has it's own time management. You can never be sure that the programs' bookkeepings of used times do 100% agree. In fact, deviations wan't be avoidable with the elapse of time. E.g., the communication of moves will take some time (with auto232 time, these spans are even of the order of seconds). Some programs don't seem to account for the time which they use to scan the opening book. And so on. IMO, for these reasons you can't rely on the time book-keeping of one of the competing chess programs. Other points of doubt could be: have both of the programmers correctly implemented the criteria for draws (50move-rule, ...) ? Discrepancies are possible. Therefore I think that a clean solution for automatic play must include a referee program, which should be a complete chess-machine (to be able of keeping track of 50move rule, repetitions, ...). Regards, Uli
