At full ring micro a 3 bet is often extremely strong. This makes 3 betting a strong play at these stakes. A weak/tight would probably not call with AK or better- so post flop should be easy- even though we would have to fold more often than not.

When we are bet into we can fold. If we flat call his preflop raise his range includes more air (ATs+) and we can win more pots post flop.

Hope your luck will turn around.
