15 moves. Yep this is 100% how majored my games go lol
actually a lot of times low elo players even in the 1000s don't know how to deal with pawn rollers. If you want to try it, play moves like f4 and g4 if they attack an enemy piece and roll with the pawn storm.
I looked at it like a peaceful but dangerous if you have no idea how to beat it.
