Hi Dr.,
today's strong engines all use some witchcraft called magic numbers.
Though I have not been initiated into it, I hope to improve BigLion soon.
I don't regret however that I spend my time on ChessGUI :wink:
Best,
Matthias.
Your GUI is just fantastic,it won't be long till I switch all of my tournaments and games there :D

It is very unstable still in the interval between games, if user is clicking around.
Therefore if used for bullet games, clicking around may stop a tournament between games, forcing a manual resume.
So test well before you transfer :wink:

Best,
Matthias.
My engine was quite strong till I added knowledge to it.

can you check whether BrightFRC 0.4a rejects b1c1 in this position ?
b1a1 is of course stronger.

[d]rk1b2rq/pppn3p/3pp3/4p1p1/4P1n1/2PPBNN1/PP3PPP/RK4RQ w GAga -
You got me there! :(
From the command line:

Code: Select all

% Kc1
ambiguous move: O-O-O _and_ Kb1c1
invalid move: Kc1
I guess it is a parsing bug I need to fix.
It's been a while, do the FRC rules say that all castling moves must be specified as either O-O or O-O-O? (then it would be a simple fix)
If not, how could Bright differentiate between the castling move and the plain king move?

My engine wanted to send a castle to Bright, but mistakenly format b1a1 as b1c1 :evil:
So I too still have something to fix :wink:
This bug lets BigLion play legal but weak unintended moves.
Castle is always "King captures own Rook", here b1a1 .

Don't go the O-O-O way because of other problems there !!

Best,
Matthias.

I don't understand FRC castling rules myself... :shock:
But I do understand that they are very difficult for engine authors to implement. I've lost count of the number of engines that have had castling bugs in my testing. The good bit though is that for the most part the authors managed to fix them :)

Yes, I used the new bitbases. It is version 3.2.
Without bitbases I had no problem.
The position I gave is the end of a study.
I was wondering why bright could not solve it.
It was white to win, but resulted in a draw, as you can see.

Kind regards

So it looks like bright works as exspectet +without+ bitbases.
Bright +with+ bitbases may cause errors.
