A call looks best on the flop with only a OESD, not a fan of raising and getting it in really.

Turn I'd have check shoved or c-c depending on their sizing. Not sure I like the donk for pot, expecting to get shoved on by tons of hands we are behind and fold quite a few marginal hands like PP and weak Tx.

Pre: Seems reasonable.

Flop: I like check calling here trying to keep the third player in the pot.

Turn: I think I would be checking again here and reacting to villains sizings accordingly. Check calling and check raising both seem reasonable. If turn goes check check then we can bluff villain off a ton of hands then on the river by donking out then.

I don't think a flop raise is out of the question here, even though calling is perfectly fine.

The raiser didn't c bet so we expect him to not be strong, and the last player to act only makes a half pot bet probably expecting to take it down a decent amount. I think we have a ton of fold equity by looking so strong when we raise in a multiway situation, and of course we juice the pot for when we bink.

If we raise and get shoved on I'm not particularly bothered as we have 7 high and it's always difficult to get decent value with draws when OOP anyway. If villain only calls then we can expect him to be capped and look to fire the turn and possibly most rivers.

As played I would check the turn. Not sure about check shipping without a solid read, but we can call a small bet, and if villain checks back then we have a bluff opportunity on the river.
