Re: Safe mobility?

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 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

Another engine vajolet2_2.3 does null move at depth >=ONE_PLY according to the following code excerpt...
