It is interesting, but people are drawing the wrong conclusion from it. For one, LLMs don't go through a "chess learning phase". They're not analyzing a board as they're learning the rules or studying games to create a coherent model of chess. They're just imbibing raw relationships as isolated fragments of information. The fact that they can't unify this into a coherent model of chess playing in one shot and execute a competent game says nothing interesting about the limits of their intelligence. If you give frontier models the rules of chess in their context window, could they perform only legal moves? I bet they could, excepting trickier scenarios like pins and failing to respond to a check. But those kinds of scenarios have to be reinforced in any human player as well. Even Super GMs fall for mate-in-1's occasionally which is functionally equivalent to those kinds of failures.
