I think check/call is your worst options on the flop. Cbetting is good because you have lots of equity and lots of good cards can come on the turn.

Check/raising flop is also good if BTN stabs a lot because the fish will often call with all sorts of crap and you can trap the dead money.

The turn check/raise makes no sense. You have plenty of showdown value with your top pair, but raising pushes out nearly all the hands you are ahead of. So just call.

Your hand is pretty well disguised. It's quite unlikely villain puts you on a K and if you hit your flush I don't think he sees it coming since you played so passively. So you could check/call on a blank river and hope villain tries to push you off 9x and when you make your flush you could either go for the check/raise or lead out.

Are you trying to bluff OTR ? What do you expect him to call here ? I think c-betting the flop is reasonable, the problem imo is that you multiway drawing is expensive. Dn't like the turn x/r either, you have TP+FD a great hand to call the turn. Same goes for the river. You were overplaying your hand OTT/OTR.

Yeah I think it was a bad hand. I think betting to have some fold equity is better than checking/calling to hope to hit and make a big hand. I think the raise OTT is not good but i wanted to build a Pot, because I have pair +2nd NFD. But I think, check calling is fine and raising oder leading river if fine.

I dont mind ch/c flop here to balance our range on a board that conventionally hits villain's range harder than our own so we can have some really robust equity and to uncap our ch/c range so we aren't getting owned by villains OOP on club turns/rivers where they can auto-profit by barreling hard. I may then choose to ch/r some blank turns as well as those with a club, however ch/r in this spot is a pretty big mistake imo, after ch/c flop im always ch/c this turn unless villain is short-stacked in which case ch/jam is obvs fine where they have to call off ATC. If the river bricks im leading for value as all 9x is checking back as well as TT-QQ. I'm not too worried about making busted draws fold as we block a good number of these and as a result i would argue villain has a fair number of weak-showdown type hands we want value from as well as balancing for when we have busted draws ourselves.
