Shadow Strike Question

Shadow Strike Reads > > [obt] Strike: strength ranged damage, with an optional maneuver. > [OBT] As above, with an optional press. > May I select that strike during strike selection (not having used the maneuver) can I use the maneuver on another round of combat?

No. Rulebook 6.4.2: "If a combat card played by a minion has a maneuver as part of an effect, the maneuver must be used that round of combat."
