Is there any chance to get bright 0.3a?

It seems to be 40 points stronger than 0.2c. Allard Siemelink hasn't answered to PM or written to CCC in some weeks now.

So is it a private engine but can be obtained by asking for it by PM?

Hi,
On a core 2 duo machine after a 188 games at long time control using it's own opening book i got this result in my rating list:

Bright 0.2c MP 2712_113/188

I'll be more than glad to test the next Bright :D

Well, it depends. :)

Anyway, I guess I could release bright 0.3a as a public version if there is enough interest. Anybody?

When something is fun and free, of course people will be interested.

Of course there is plenty of interest Allard. :P
If you make 0.3a public, could you please also make 0.2b public? :wink:

Regards, Graham.

From testing Bright 0.2c, I know it is a very interesting engine.

(that was from empty hash)

Best mini-match result was 4-2 against Naum 2.0, in that test (which was single cpu only).

It's strong, and also with mp capability and bitbases access (something to wish for would be multi-pv). I consider it among the most interesting freeware engines, or among all engines at all. CCRL is showing Bright on rank #4 of all free engines, or #3 if we include version 0.3a which they are testing already.

I'm sure any improved release will be widely appreciated. Thanks for this good engine.

Yes, Allard I would be interested. Bright had a very interesting style and was quite good in testsuites. Unfortunately I could never get it to work on my Quad 6600. I thought it was because of Vista however I've since installed XP pro x64 and it still gives a message "bright 0.2c has encountered a problem" in Arena. It works on my dual 6600 though. Perhaps its how it was compiled. I hope I have better luck with bright 0.3 since I like aggressive engines. Thanks again for your engine.

Paul
