erpel, i think the discrepancy here lies in the fact that 18/13 with a 5% 3b is nitty at all at FR, it's actually quite loose. it's prolly the equivalent of like a 26/20 with a 6-7% 3b at 6m, and i think opening A2o against a player like this is just suicide. so we're gonna end up opening a relatively strong range OOP, which sounds like a recipe for opening for 4bb's
