[Harv72b]

I lean towards raising because I think my hand is best a significant portion of the time, and I hold out the (perhaps vain) hopes that this will set me up to take a free card on the turn when CO pees his pants & BB decides to go for the ol' turn c/r again.

As played, I call the flop 3bet because we're getting almost good enough immediate odds to chase our 4-outer and it looks like we can be confident of winning a huge pot when we hit it (and you never know when our A outs are good as well). Even knowing that it's likely to be capped behind us I think the implied odds justify continuing.
