Theory of Mind (ToM) enables individuals to infer others' intentions and beliefs. While existing models successfully simulate recursive ToM reasoning, they typically rely on a fixed strategy at the lowest level (e.g., Win-Stay-Lose-Shift). We introduce a novel ToM model that combines a dynamic belief over multiple strategies with recursive best responses at higher levels. Using simulated data from a Matching Pennies game, we show that the model accurately recovers underlying strategies, adapts to changes in the environment, and correctly infers the ToM level of the agent. This approach offers a more flexible and robust framework for modeling strategic social reasoning and opens new directions for understanding decision-making in interactive settings.
