We're obviously using different meanings for "good" here. But aside from that, it took 100's to 1000's of reinforcement iterations for your brother to play competently. While certainly impressive, that is still an entirely different category from piecing together disparate facts learned during training (LLMs aren't analyzing a board as they're learning the rules or ingesting PGN files), to executing a competent performance in one shot.
