When to Call with Ace High

[Moozh]

I've had a few discussions about this topic with my roommates. There are definitely times to call the river with no-pair, but they're often hard to describe. One place to do it is when you raise pre-flop, bet the flop, and check the turn for a free card on a rag board. After the turn check, you'll be bet into by almost anything. Another time is when you're up against a player who is over-aggressive.

Villian here is 70/30 preflop (way too loose and aggressive).
