Re: On-line engine blitz tourney October

One hour earlier would be great for us in Asia if it is convenient for HGM.

Re: Safe mobility?

If the engine is too weak to measure such tiny Elo gains (which shouldn't be true if it's any gain at all, actually, but I suppose you mean it takes a long time to get a statistically significant result), that should tell you that you need to focus on more basic (and boring) evaluation terms first....

Re: Safe mobility?

Relying on "common sense", rather then measuring and adopting the scientific method: that's exactly where the difference lies between amateur and strong engines… Fully agreed. Since the engine is weak, avoiding simple traps seems to be among the first things to do and my engine does it reasonably w...

Re: Safe mobility?

That is part of my question. I don't know if safe mobility is good. I do know that my current mobility is not good, and that my program often loses to programs it outsearches by having pieces trapped and not seeing the capture in time. My engine "Nameless" uses attack maps similar to those in Ed Sc...

Hi Norbert,
Thanks for the post. You have nailed the problem. I have not installed Visual C++ 2015.

Re: MadChess 2.2 Released

I installed in Arena by the following path:

C:\chess\MadChess\MadChess-Win32-2-2\MadChess

This directory has the executable and many dlls, but not the missing one.

Re: MadChess 2.2 Released

I installed the 32-bit executable in Arena 3.0 on my windows-7 machine. When I tried to run an engine-match I got this message: MadChess.engine.exe - System Error The program can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer. Try reinstalling the program to fix this...

Re: tt move vs null move

Barbarossa does null move at d==1. I just made a branch to try this. But it will take days until I can see significant Elo results. I will report when I have them. Your result would be interesting. Another engine vajolet2_2.3 does null move at depth >=ONE_PLY according to the following code excerpt...
