 Just as Backward Induction, dominance reasoning has an iterative flavor. Assuming common belief of rationality, players can expect their opponents to also drop dominated actions from consideration. Doing so reduces the game and might render further moves dominated, as is illustrated in the following example. Within the left-to-right temporal progression, moves are greyed out as they get discarded. Players’ preferences are represented with numerical values with 1 the best and 4 the worst.
