It is imperative for any program after having completely outplayed his opponent to keep him from escaping defeat and this is why we should test different programs NOT only to see if a few can find the drawish line, but also to see how many programs can prevent their opponent from finding the drawing resource. Therefore, it would be interesting also to find which programs don't make the critical error on the previous move by allowing their opponent to escape with a perpetual check. Pichard
