[Foucault]

Good hand to post, I've thought about it quite a bit without yet reading responses. In the end, though, I think that unless LFTV rivers quads, it's a pretty meaningless decision. Check-call and bet are going to result in basically the same hands paying off or extracting, as the case may be. The only difference is when JJ has a high hand good enough to scoop, in which case he raises and LFTV is priced in to call (JJ also raises good lows and probably hands like flush/trips plus any low that have scoop potential) but behind JJ's range. JJ knows LFTV can't have a low unless he rivered it, so he's never getting bluffed off of a low.

So c/c, or c/r if you improve to quads.
