I know about the "players don't announce Moves, they are supposed to describe their actions" part. Let's say a player describes how they hides to ambush someone. The GM asks for a roll, because the player used a Move here. Which one?
As a GM, what move am I supposed to choose when my player is trying to hunt/trap someone?
For instance, the Thief has their "Backstab" move:
When you attack a surprised or defenseless enemy with a melee weapon
But how do you get your enemy surprised? By ambushing them, supposedly.
As far as I know, Defy Danger (DEX) are traditionally used for stealth, but not in this case, I guess.
Defy Danger explicitly states
When you act despite an imminent threat or suffer a calamity
However, when you're hunting/ambushing someone, there is no imminent threat and no calamity. You're hiding because you don't want to spook the victim, not because you want to avoid any kind of danger. So what move are you supposed to use instead?
