I think that some chess programmers must have thought this question some time. I remember a 'mate in one'-position having 175 or so legal moves. Over 100 of them were mates. Perhaps someone has statistics from 'real' games. BTW: What's the average number of moves precisely? I know it's about 30, maybe a little more. (In middlegame anyhow.) I already know, that minimum is zero (in mate or stalemate. :-) (I _may_ have some use for these information in my new program.) Jari
