Assuming you've got 2 cards that the flop missed, and not holding 74o "The Rippy".

I like this move and use it from time to time with success at 25NL. I look for the tight/passive types on Poker Tracker, or an opp who I've seen lay down to a scare card or similar threat in the past.

A read on opp's frequency of c-betting helps too, since you're hoping ideally that the flop missed him. Another good situation is where he is holding AJ/AT or lower and is afraid he might be outkicked. You're representing either a strong AK, or a loosely called A7/A4 that hit two pair on the flop, or even a non-slowplayed set.

The one downside that I see to this line is that it is expensive. You're betting $18 to win $14, so it needs to work (opp fold) a little more than half the time to break even, unless he calls and you catch something on the turn and can proceed to take down a big pot.
