Amoebas got teeth!? No wonder dysentery is so nasty.

This is quite interesting and a delicious compliment to hgm's array based dissertation.

Is Madchess the strongest dotnet engine now? (besides the SF clone)

There were some very recent games on TCEC between Komododragon and Stockfish. I went to go download the games and I cannot find them.
Does anyone know where they went? They looked very interesting to me.

No crashes, I guess the problem is buffering. You probably build on Unix which as line buffering as a default, and Windows default is full buffering.

For some reason, I cannot build your engine properly. I used cmake to create visual studio projects and it built something, but it did not find the nodes file and the uci form for arena is blank. It still plays chess, so I guess it is using the ordinary evaluation. I tried using mingw and it found t...

There is no reason to fumble in the dark, when you have a lantern, and so does everyone else.
