To Thinker 5.3B Inert testers !

unless the author of the engine has made specific adjustments, Winboard engines will play much weaker in Chessbase GUI against other native engines than in Winboard

Engine authors must be very smart then, because I've not noticed any stunted performances from engines using wb2uci adaptors.
It's a bit of an old wives' tale I reckon.
Strangely enough, it's winboard engines not using the adaptors that give me the impression of underperforming under Arena. I mentioned this before, but got pooh-poohed by the Arena fanboys. Could well be a false impression of course.

Cheers, Graham.

PS - I've nothing against Arena. It's a fine free GUI which I've used extensively for testing.

Ok, can someone explain Silvian why 1% loss of speed isn't a loss of 20-30 ELO? I tried at Rybka forum and failed....

You chase me !




Two years ago was on CCC a long thread about this problem. Very instructive to find and to read it !

About wb2uci I keep my opinion: a loss of 1%.

Nothing wrong with people having different opinions.

Ok, sorry about that, I just want to know, do you think that doubling the speed of a 2000 rating program (100%) gives a rating of 4000? Because that's the logic you're applying to the 1%.

[Ovyron]

Isn't he talking about 1% loss in strength (not in speed)?

1% of 2500 (Elo) is 25.

That's what I explained at Rybka Forum, elo is offset arbitrarily, Rybka at 3200 and Zappa at 3000 rating equals Rybka at 200 and Zappa at 0 rating, then you can't take percentages out of an arbitrary number.
