I had my 8-core Ryzen 7 computer spend about 2 months generating quick Stockfish-vs-Stockfish games. The result is 3 million games that I think could be used for training neural networks, or to tune evaluation functions.
I have the games available in PGN format with comments that include the score and search depth, or in a much more compact and easy to parse format: One game per line, consisting of moves in UCI notation followed by the result at the end.
Code: Select all

At least one person in this forum has expressed an interest in the data. I will make it available soon, but I wanted to ask this: Would you be interested in the PGN version or the games, or is the simple format enough?
