I like playing A6s suited there. The flop action is definitely a big hand. It's equivalent to a turn raise in terms of a danger sign. So you're up against at least two pair and quite possibly a set. There's no drawing for cheap after that. Continuing here is essentially calling all-in which makes it a math problem. Do we have enough equity? Well: 1) we haven't put any money in yet just 4 blinds, 2) we don't have a made hand lol and we only get there a third of the time, 3) we can't assume both players come along so we can't count on 2:1 pot odds, and 4) even when we get there they have significant redraw equity. So that's a fold.
