A set of desirable moves at the given stage of the game.

The term is taken from book of Brian Upton. It's used to show that when a Player has many moves (wide "horizon of action"), but only one of the moves is clearly good and the rest is bad, Player's choice is actually illusory. To enjoy choice Player has to have a set of moves to meaningfully choose from (sometimes called viable moves).
