Villain is a bad lagtard, running at like 43/27. The sample size isnt enough to get decent AF but hes been aggro. Does anyone like this line, or should I be folding the turn? I think that against this player once I flop TP, I have no choice but to stack off, but I could be persuaded.

Also, what is optimal preflop? I hate folding and coldcalling, but I also hate building such a big pot with ATo.
