I think this is misunderstanding what’s typically going on in archetypal OSR play.
You’re not “avoiding triggering the rules”; that a player is allowed to attempt something using fictional positioning is very much part of the rules that people play the game by (arguably the most important rule, for a lot of people).
The “cleverness” is in being able to suggest that the situation in question can be resolved through the use of a bespoke move outlined by the player (typically to their own advantage; otherwise it’s not really all that clever). Perhaps in the most lopsided of situations this results in the situation being resolved by clear declaration of fiat, but in many cases it’s far less clear-cut.
In OSR play, everything that exists in the fiction can potentially have teeth, because everything that exists in the fiction might potentially be a challenge or a way to overcome a challenge; player cleverness is in figuring out how to hook into those teeth. This is, I think, rather the opposite of “fictional positioning without triggering a move” that happens in PbtA play.
