I don't know how aggressive you've been playing. It's 3-handed so you might get it all-in vs. Jx on this flop.
Possibly. I've been very agressive following through once and twice after I raise, and leading into button raises after the flop. But I think this guy can still see some serious strength in an all-in. Especially on such a drawless board. Which is why I prefer waiting until the turn to bomb it, if possible. Which is why I kind of hate my turn check now...

What's your line if the flop was 2-tone?
Not sure what I'd do, probably vary up between pushing and calling and getting it in on most turns.
