TCEC - recent komododragon verses stockfish games...

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.

Re: Introducing Igel chess engine

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 this reason, string based protocols can be problematic on Windows unless you change the buffering for all of the I/O that needs changed. std::cerr...

Re: Introducing Igel chess engine

That is exactly what happened. It was compiled and placed in the src folder. But when I run it, the UCI commands mostly do not function. ... and before you run the g++ command you also created a folder weights inside src and you downloaded the official network file ign-1-139b702b to it, right? so t...

Re: Nalimov errors

It does seem worrying that they MD5 hashes for the same file are different.
I suspect it is default sizes for structs, perhaps a different packing rule.
Modern compilers tend to pack on wider block sizes.
Are the files that you built larger?

Re: Introducing Igel chess engine

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.

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