Please see: http://chess.grantnet.us/Ethereal/ for the non-technical information
Regression tests vs Ethereal 13.75:

Code: Select all

Standard Chess using a very drawish book:
ELO   | 45.54 +- 1.58 (95%)
CONF  | 60.0+0.60s Threads=1 Hash=64MB
GAMES | N: 40000 W: 7091 L: 1878 D: 31031

CCRL blitz results are there

Ethereal 14.00 on 8CPU - +44 Elo (Ordo: +58 Elo)
Ethereal 14.00 on 1CPU - +39 Elo (Ordo +49 Elo)

Seems to be a fairly consistent picture comning out of all the various tests.

So ignoring Fat Fritz, which I always do, it is the Number 3 engine, just. Koivisto 9.2 might have something to say about that though when tested.

Koivisto 9.2 is not an official release.

Koivisto 9.2 is not an official release.

Ah yes, I simply saw the thread here that it was "available". But looking at that thread, it is only an Ipman compile of a development version. Explains why no-one is testing it. Nevertheless, the current Kovisto dev version will give Ethereal a fight no doubt.

AMAZING: vs Stockfish 230202 avx2 : 1000 (+ 0,=639,-361) .
There are a lot TB fixes now. Andrew have you measured TB gain for Ethereal?

Where do you see this result?

Even with biased book I see one win for ethereal out of 500 matches when only 1.5-0.5 is considered as win.
