Pedone 1.3

[Fabio Gobbato]

Mainly a bug fixes release. I solved all the stability issues of 1.2.
The ELO improvement is very small.

The changes:
Bugs fixes
Tuning
LMP until depth 3
Small code optimizations
Improved king safety

Thanks.

[Sylwy]

Thank you a lot, Fabio !

[Ralf Müller]

Pedone has a very nice playing style.

I have found a problem of Pedone with Arena. I have updated the package to make the engine working for this GUI.

[Fabio Gobbato]

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.

Hi Fabio,

I saw for minutes an mistake in my engine configuration for Pedone 1.2 BMI2 x64.

Code: Select all

[ENGINE]
Name=Pedone 1.2 BMI2 x64
Author=Fabio Gobbato
Filename=C:\Chess\Shredder_12\Engines\Pedone\Pedone_12-bmi2-x64.exe
[OPTIONS]
BookFile=<empty>
AlwaysBestBookMove=false
SyzygyPath=SyzygyPath=c:\Chess\_syzygybases

I think at this time I do that I be drunk.
SyzygyPath are not correct.

I fix that for Pedone 1.3 BMI2 x64.
Will be start after still running Octochess and the comming soon ProDeo test-run in around 8 days.

Sorry!
And thanks for your engine version 1.3!

Best
Frank

PS: OK, Pedone 1.2 without 4-pieces ... perhaps 5 Elo. Such a mistake I had in EXchess 7.51 configuration too I am to old for all this!

But you can be sure that the new version 1.3 will be start with full power.

Bug report for version 1.3 under Shredder Classic GUI:
If I edit a position ... example:
K vs. KBN and start Pedone 1.3 for looking endgame bases works or not, engines do nothing and GUI crashed. I can see that bases found but engine do nothing (again, only if I edit a position). Same for Pedone 1.2 with a bugfree configuration!

[Fabio Gobbato]

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.
