Just a couple thoughts - as you said, at 2NL you're pretty much always getting a call cause these players are bad. But then you're playing out of position to a person who could be holding a wide range. What's your plan for the flop if you miss the flop and you've got one caller?
I'm not trying to tell you not to make this play, but how you answer that question will determine if you should have made that play IMO.
What's your plan if you missed and there's an A on the board, and what's your plan if you missed and there's no A?
