Lots of action with top 2

This look standard? Villain is fairly loose and quite passive (more so PF).

Looks good but I don't like completing the SB with a hand like K9o
If everybody limped and it was suited I might consider it. Otherwise I instafold this pf

If villain is passive isn't his push likely to be 44 or 99? I like the 3-bet but think that I would fold to the push. I guess he might also do this with A4s, or some flush/str8 draw, but that doesn't seem very passive. And you are not that much ahead of one of these combo draws.

The only hands that hero beats that I can see villain pushing with are AA and AK and I would expect to see a raise from them preflop.

Although you may want to disregard my advice as I only play $50NL.
