In addition to what others have said, someone posted on r.g.c.c that Shredder 7.04 has also had an easier go so far. Shredder's opponent rating is the lowest of the top 21 engines tested. It hasn't been tested against Deep Fritz 7 yet, which the Shredder 7.0 had a very difficult time with. As Dann reminded me yesterday, there are error margins, which show that Shredder 7.04 isn't statistically better, yet. So this tells us what we've known for a long time. The top engines are all approximately equal in playing strength. Shredder 7.04 2810 - 34 = 2776 Shredder 7 2770 + 27 = 2797 Fritz 8 2762 + 26 = 2788 Deep Fritz 7 2761 + 28 = 2789
