chess / commentary tagger

A fine-tuned LFM2.5-Encoder-230M reads chess commentary and tags every move, piece, square and claim; chess.js then checks each claim against the board. I built it to reward true reasoning during RL (the story). It runs in your browser: the first load downloads the model (~145 MB) from Hugging Face. Code and data are on GitHub. Pick an example or write your own.
