This version is definitely much weaker than 0.6,it's obviously a downgrade....till now I have near 28 games at long time controls and it's performing much worse than Hamsters 0.6

[Alessandro Scotti]

I have played more than 3500 games with that version, it's definitely not weaker in my tests. Maybe it has bugs at long time controls I don't khow, but 28 games or even 280 are not enough to draw conclusions.

Hi Alessandro,
approaching the 40 games barrier along with Hamsters 0.6 and still....Hamsters 0.6 is performing around 30-40 elo better,the time control is 40 minutes + 20 seconds increment....
It must be a good blitzer,but Hmsters 0.6 is a long distance runner

Well I hope that old Hammy is just on a luck run!

One thing that really drives me crazy in computer chess is the amout of games you need to compare versions. I usually run tests in batch of 900 games, using the Noomen positions with black and white (100 games) with 9 opponents about the strength of Hamsters. I give you the results of three such tests, performed under identical conditions:

422.0 / 900
444.5 / 900
460.5 / 900

The difference between the worst and the best result is a huge 38.5 points, which... well, that's why I go crazy!

Don't worry Alessandro,that how life goes
I've erased Hamsters 0.7.1 MP games from my rating list and I'll start testing it from scratch as a single threded engine....I'll keep you informed when I pass the 200 games barrier
