Re: xboard and fifty move rule

So why adjudication works if I edit a game with an engine launched and it doesn't work without?
It's not wrong adjudication if you can edit a game with a 101 half move counter.
I know it's not a problem because it does not affect the game play, but it seems wrong to me.

Re: Test suites

I want to use test suites as a fast and rough test for my engine.
I think that tactical, middle game and endgame suites are suitable.

Test suites

Where can I find good quality test suites with more than 1000 positions?
I have already tried STS.

Thank you

Re: FCP: Pedone 1.3 BMI2 x64 is still running!

It's correct. The strength of the 2 versions in single core is very similar, but version 1.3 is more stable and I have solved a bug related to the parallel search. The 1.3 is a little bit more agressive due to an improvement in the king safety. In the next release there will be a good ELO improvement.

Re: Is possible to improve likelihood of superiority resolut

I tried in the past to collect statistics of the searches for tuning.
For every search launched by the engine I stored in a file the depth reached and the node count.
The idea was that the better version should go deeper and search less nodes.
But it didn't work.

Re: Pedone 1.2 (mistake by myself) and bug report to 1.3

Thank you for the bug report.

Have you got the debug file with the commands that the GUI sends to the engine when you edit a position? It would be useful to understand what happen to the engine.

Thank you.

Re: Pedone 1.3

The problem come with arena 3.0 that send "go ponder" in a checkmated position.

My engine with 0 legal moves crashed, now I solved this case.

With winboard this problem doesn't exist.
