UTG call is okay; I'd probably fold it but I like limping suited broadways UTG at passive tables and this is just one short of that.
On the flop, we have a great draw but our flush is not to the nuts and we don't have overs to suck out with. Our play is to raise the initial bet to $40. This is really strong with our tight image. We are pretty much repping only sets and monster draws on this board, but our hand is actually a little weaker than that, so we can often get better hands (sticky top pairs) to fold to a big turn barrel. We win the pot often enough here, and when we don't, we usually isolate ourselves in position against the SB, which is a great result.
I tend to raise or fold my draws unless they are to the nuts and IO is on our side. So the other option is to just fold the initial flop raise...but I don't like that at all because our equity here is great! So yeah, I definitely raise this to $40 on the flop.
The way we played our hand kinda turned it face up. We called twice and it looks like we are on a flush or straight draw, which kills our implied odds when the draws hit and increases our reverse implied odds.
Since we didn't raise the initial flop bet the good play is to just fold to the $50 reraise.
Raise the initial $13 >> fold to the $13 >>>>> fold the $50 >> shove on the $50 >> call the $50
