This table looks fun. I'm calling. Folding seems super standard against regs or unknowns, but these guys are wild and probably don't see it as unusual when the sb cold calls a 4bet here. 5b seems thin value but I see bikes' point. I just don't expect us to narrow it to HU very often when we 5b, so I anticipate many awkward flop spots when called, and obv it's hard to continue when someone 6bets. So yeah call > fold > 5b/f imo
