Plus of course not all matches are going to end the same ways. If you match Deep Fritz 8 versus Shredder 8 in 4 different matches of 30 games, I expect differen results in every single match. In one match Shredder8 might be the winner by 3 or 4 games and in the second match Deep Fritz 8 might result the winner and so on...... Jorge
