Summary: The aim of the paper is to bring to the realm of game theory the well-known deontic notion of contrary-to-duty (CTD) obligation, so far not investigated in relation to optimality of strategic decisions. We maintain that, under a game-theoretical semantics, CTDs are well-suited to treat sub-ideal decisions. We also argue that, in a wide class of interactions, CTDs can used as a compact representation of coalitional choices leading to the achievement of optimal outcomes. Finally we investigate the properties of the proposed operators.
