This topic comes up a lot and I've read a lot of threads on it, but I'm still not quite sure about this.
I know I can make a move when players look to me to know what happens, and I know I make moves when I'm given a golden opportunity. But what if the players know what they want to do, keep making moves, and continue to roll well? Do I interject moves that the fiction dictates anyway? (I was listening to the Walking Eye podcast after this week's game, and I noticed the DM there struggled with this as well. His creatures seemed to be inactive because the players kept rolling well.)
For example, the players were essentially surrounded by worgs, and had more or less worked themselves into a natural turn order, as part of the conversation (admittedly, they are used to D&D and Shadowrun, etc), and although there were many threats looming (the worg's masters joining the fight, being grossly outnumbered and surrounded), they navigated successfully through continually rolling well. That itself isn't the issue (because I'm a fan of the characters!) but rather than in the fiction, it seemed like all the worgs were just standing there ready to be slaughtered, because I didn't want to interrupt the flow to interject a soft move, especially when the players had done so well.
Is this merely fictional? Should I have depicted the worgs as, for instance, attempting to snap at the players but being successfully turned away or avoided?
