It does not include Shredder 8. So the question is not answered by either list. However in my blitz database Shredder 9 is running about 30 Elo above Shredder 8. I only have a couple hundred games as I had to restart all games after playing over 500 games with Shredder 9. I did this because Shredder 9 draws games it should have won in tablebases when using 5/0 time control. I have started playing 5/1 blitz games and it cures the problem. Jim >Helmut
