Sometimes programmers prefer the approach to terminate the search as soon as a mate in the tree had been detected. This sounds reasonable; usually it suffices to find a mate in order to win the games. In case a mate had already previously been announced this may lead then to the weird effects which you have observed. I have already seen a case where a program was continously announcing mates and finally drawing by a repetition of position; unfortunately it was my prog. -:) Uli
