I think preflop looks fine. You're setting yourself up to have 1 potsized bet on the flop if they both call, and you should have some fold equity vs BTN if he is competent. With really bad aces it becomes more iffy, but your hand has a nut suit, and can flop both wheel and broadway gutters, which helps a lot when you need to shove into 2 players on the flop. I don't think flatting here would be bad, especially since you have good relative position postflop, but 4bet seems fine as well.

On the flop, they should have trips+ about 40% of the time. There was a similar thread on 2p2 not a long time ago, and we did some calcs there. Besides T+ there's nothing that has enough equity to call you, because you block the straight outs. You can probably guess that with 60% fold equity, shoving the flop is very profitable even with zero equity when called.

there are probably more subtle ways to go about playing this hand. One way is to bet smaller and allow your opponents to make a mistake. What you do if they raise is totally read-depended, but at least you create a potential for a higher edge. 

pf seems fine.  I think I probably just bet small and call it off against one and fold against two.  I think that plan is exploitable but I'm not sure that anyone is exploiting it.  I'm not sure if shoving is best, but I'm sure it's profitable.

Nofox, Here you go:

pot 263 at ~275 effective?  no need to get fancy just mash the pot button imo. preflop is good.

Just out of interest.  How do you feel about this if it's 5 card. Let's assume your additional card is a raggy diamond.
