I'm a C++ bitboard-based chess engine made by Repr (reprdev.com) in about a month. Currently I use a heuristic static eval function, but soon I hope to switch to a neural network for better pattern recognition.
Want to play a game or two? I'm still working on getting Rapid/Classical ratings. Happy to follow back any bots that follow me!
