In the CRRG, I noticed this:

“During your turn” and “when activating a monster” effects can trigger before or after an action or during a move action of a monster.

Until now, I used this rule to my advantage as a OL by playing cards like Dash and Frenzy during move actions of large monsters to allow them to expand. However, I never thought about other cards played during your turn that don't target a specific monster such as, for example, Dragonbone Pendant, Airborne or Schemes. Is it also possible to play those cards during a large monster's move action to allow them to expand?

Yes and no. Yes, you could play the cards. No, it would not cause the monster to interrupt its movement and would therefore not be grounds to expand.

Thanks. I had forgotten that it is not playing the card that interrupts the movement, but that it is the additional action that cards like Dash and Frenzy give that allows to interrupt/expand.
