Hello Dann, It's surprising to me since I have played a lot more games (S9 650+ and S8 2600+) and S9 is definitely stronger. I add my database to all others I have seen here and I feel pretty confident that S9 is stronger than S8 at all time controls. So when one test shows up the opposite I am surprised. I didn't say it was impossible or even improbable. Just surprising. Jim
