Opening Stuck Doors. 2-in-6 -> STR check with disadvantage.
While I agree that rolling for things you want them to succeed at can unecessarily stunt the narrative, when combined with the idea in this article of rolling to see how well or poorly you do it could be used to give you narrative fodder. Like this example of the door. You don'tneed to roll but rolling might give you a nice connecting moment so you'renot skipping through the adventure to the 'good' stuff not having any fibre in amongst the sugar.
