I'm happy you enjoyed it! There are definitely a few rough edges, yes.

Since the whole thing is executed in the browser (including the model) there aren't a ton of secrets for me to keep. Essentially it is expectation maximization: the bot tries to find the move with the highest value. What is "value"? Essentially, it is the dot product between the probability distribution coming out of the model and the centipawn evaluations from Stockfish.

In other words if the model thinks you will blunder with high probability, it will try to steer you towards making that mistake.
