The authors train separate AlphaZero agents under nine altered chess rule sets and use self-play to examine how rules affect outcomes and opening preferences. In 10,000 one-second-per-move games per variant, No-castling chess draws 84.41% of games, versus 88.20% in Classical chess. This model-based comparison suggests rule changes can alter play, but does not establish human outcomes or isolate causes.
