An LLM has been trained to do everything it does blindfolded, "only" using perfect recall of everything in it's hundreds of thousands of steps of context, and hundreds of layers of KV cache. It's a computer - it has a massive advantage over a human.

The fairest apples-to-apples comparison of an LLM whose training data included chess games would be a trained human such as Magnus Carlson, who can quite happily play a dozen or more simultaneous blindfold chess games.
