How Does Changing the Elo of a Chess Transformer Affect Its Computations?

The paper explores how adjusting the Elo rating input in a pre-trained chess transformer model affects its computational processes. It finds that increasing Elo leads to deeper attention layers being utilized, particularly for specific tactical moves like knight forks, with deeper heads handling more specialized tasks while earlier heads remain stable.
