Okay, but there's a difference to me in the move you describe here and the one i asked about. A Spout Lore like move involves providing a player interesting and useful information regarding the thing they asked about. The move you described here doesn't meet those criteria IMO. It's also quite a bit more constrained by limiting the GM to only narrating fiction that would make sense for a +1 bonus, whereas Spout Lore is much more flexible in the kind of benefits it can provide.Those who GM AW and DW can comment in more detail on that system - the default I would envisage for success in this case would be talking +1 forward.
In my BW game, a PC who was fighting zombies, and wasn't really skilled or strong enough to just hack through them, performed Assess actions to spot weak spots and thereby get an advantage to attack them (I can't remember now if it was +1D to attack, or +1 on the damage scale). This is an expected part of the game.
As an example of something akin to what I'm envisioning - could the GM on a success narrate 'you recall orcs will run if you hit them with a vial of acid and that you have such a vial in your pack.'
