Yes, but I haven't got the games anymore. Mchess is particularly 'good' at this, since it plays a limited, but well booked-up, opening set; and it will tend to repeat specific opening lines again and again, even if it loses them, if it thinks the score just out of book is good. Examples are french, urusov gambit typically. If you fix your programs learning (you being the programmer), to replay won games, then the result can often be long autoplayer sequences on a specific variation. It is possible to find 'improved' lines this way. With 'cooperation' between programmers to lock their programs into specific lines, I guess it would be possible, with strong programs playing on fast machines, to have quite an impact on opening theory and to find useful novelties. Maybe it would be possible to do it via a self-play process as well - new feature ? Chris Whittington
