So your going to see a very different line from me...
Whole I would like to know all the info Dr. Strange poker out, I'll give my thoughts without it.
You are OOP on two of the players in this hand and got a good flop for your exact hand, but one that is bad for your your overall early position raising range. Moreover, TP with a flush draw is one of the most misunderstood hands in Hold Em. A lot of people treat it like it's the nuts, but there's a big problem with thinking like that: you are blocking the hands that are most likely to call. IE, top pair and the nut flush draw. So when you get action (especially raises) from other players, while you can still be ahead, it's now more likely they have sets.
By taking a bet big on flop, jam on turn strategy, it makes it so only better hands call that turn jam. That's not what we want; we want to be getting called by worse draws and worse 9s, and betting huge on two streets isn't the way to do that.
I don't mind the 1/3 pot flop bet against most players. You are OOP multiway, and because in theory people can't call as light multiway (ie 2nd or 3rd pair, gutters, etc), the need to bet large isn't there. Now if this was heads up, a large bet makes more sense given this is a board where as the preflop raiser we shouldn't have hit very hard (we shouldn't have a ton of 9s except A9s, T9s, maybe 89s, we shouldn't have 44, we can't have T8 or 86), so when we don't have as many nut hands are hands that can barrel off multiple streets, we might want to bet larger just to put get more value now. And since it's here up, our opponent can call with more stuff that we can get value from given our exact hand.
In this exact spot, I do like your small bet, but I also like a check with most of your range as you will have a ton of total airballs here like every Broadway hand. The plan being to check call against most people and probably check jam against shorter stacks as your current equity against one player really can't be all that terrible. Keep in mind that a check jam looks very weird though and a thinking player would realize you wouldn't do that basically ever with something like an overpair. Meaning it looks like top set or the nut flush draw only.
As played, I don't think we can really call a 2.4x pot jam unless you think there is a chance we are ahead with a pair of 9s. UTG+1 called next to act on the flop with two players still to act behind, which is pretty strong. Then jammed into two players on the turn when a relative blank came (the only thing a Q changes is it may have given someone with a flush draw top pair). The line looks strong, and while you wouldn't think a set plays this way that often, we would need to be pretty sure we have a chance at winning unimproved to call here. So it comes down more to your read of the player.
