Bright 0.4a's play - again I am getting a headache!

[swami]

Serious Correspondence players could use this engine if they want to attain crazy/risky looking kind of position that doesn't seem balanced.

This is the kind of position where a lot of tactics happen and that's exactly where Bright excels in.

Doesn't it send Kilonodes per second where it should send nodes per second? - Anyway, Allard will know what to do.

@Allard, on this occasion, I'd like to ask if there is a chance for multi-pv in the next version. That's almost the only thing left to desire, still.

Thanks anyway. I got very good results from Bright 0.4a in the PET endgame test:

Nice PET results indeed, I wasn't aware that it did so well on this one

Yes, it sends nodes per millisecond, where it ought to be nodes per second. A gui that calculates kilonodes/second from this number therefore errouuneously shows meganodes/second.

I'll put the multi-pv request on the todo list too, but it may take a while...

[mclane]

will there be a new bright ?

will there be a new bright ?

It seems so
