Hi,

a test match against 0.70 is still running. So far it is about +40 ELO, but the error margin is still high.

Richard

Even if I think that testing agains its precessors is suboptimal, 40 Elo is at least a nice number and would mean Critter 0.8 can pass Naum 4.2 in my list.

I will start testing tomorrow.

Thx again and bye
Ingo

Very interesting, thanks Richard.

0.80 is now a candidate to play in my long TC matches.

Have you checked them out yet, Richard?

Thank you very much Richard for this new release !!

Well +40 it's a lot for an already top level engine. Congrats !

Critter has the most impressive progression so far: each new version is so much stronger then previous and this trend lasts from a very long release series. This is _very_ difficult to achieve.

Thanks Richard.
