A question came to mind after reading an earlier question/discussion (https://plus.google.com/u/0/105199399549482359686/posts/TnkhKR2TrWx).
How often to GMs out there skip a move just to let something awesome that a player narrates happen? For example, the rule book indicates that attacking an enemy who is surprised may not trigger Hack n’ Slash and the player just deals damage. If the player narrates instant death do we give it to them?
Or as another example, if a player narrates something that would kill the enemy and they are in active combat (like decapitation a la the linked discussion), but the enemy may have just enough HP that they can’t take them down with a single roll, do we give them the outcome they narrate when they roll successfully (10+)?
