How to we proceed on the turn if a Diamond comes or some straight possibility?

I'm not that worried about a draw when CO raises flop and then cold calls a 3-bet for 44% of their stack. I'm more worried about 33, but I'm probably just shoving any turn (unless I fill up, then I might bet smaller and try to get it in across two streets). In any case, with less than one SPR effective remaining on the turn I don't think getting away from this is a realistic option.

Perfect thank you

I do worry about a set here a lot but I think sometimes you just have to gamble when the pot is already too big and you have a strong hand.

But I'm not sure what else would raise and call the 3-bet on the flop. There might be some combo draws that do it, but I don't think something like Ad4d or Ad3d should be raising here. The draws like 7d6d and 6d5d, maybe, since they can't win at showdown, but then I would expect them to get it in rather than call one, see a brick turn, and have to fold.

I suppose you can just check/fold if you think they'd never play even two pair like this and a diamond comes. I do think it's a set a lot of the time-- that's really one of the only hands it makes sense to play this way-- but I don't know if I'm confident enough in it to just give up the hand when we get called. I'm not totally confident in my answer, besides.

I appreciate the answer. I was curious to how we play on bad turns, I didn't really consider a set TBH I assumed most players would just shove a set on the flop
