Lohn: Adding the Strongest Possible Move to Rock-Paper-Scissors Only Buys You 55.6% — Fukai Reads
An arXiv preprint by Andrew J. Lohn of Georgetown's CSET, solving what happens when you add "Dynamite" to Rock-Paper-Scissors. Giving one player the strongest possible move raises their win rate only from 50% to 55.6%, and the wins arrive through Rock rather than through Dynamite. Widen the move set and the gap shrinks further, while undominated moves quietly drop out of the optimal strategy.
