Long time live NLHE player but finally decided to join 2+2!

So a few days ago I was in a super loose aggro 1/2 live game with a $5 straddle almost every single round. The avg. stack is around $250, there are a couple of short stacks (~$50) and I'm sitting on $500

I'm in the hijack position with 99 and limp in to a $17 pf raise with 6 other callers.

Flop comes K49

The big blind bets $20, UTG goes all in for $43, 2 players after him call. When it comes around to me I re-raise to $200. Everyone else folded.

The board ran out and my set of 9's held up.

I invested $60 and won ~$260.

Is this the correct play here? I was worried about the flush draw and wanted to get them out of the pot. Or Should I have raised smaller to induce another call and not worry about the flush? Was there a way to extract more value out of the hand?

Can you please explain if this is the correct/incorrect play?

Sorry if this post is poorly written - this is my first post!

I think it was played fine, with that much in the pot already you don't want to be raising 120 and giving great price to draw. (7 players pre, so bb raised 20 into 120?)

The play is fine. But don't think you're chasing any flush draws out. On the board, with such a building pot, any flush draw should gii with two cards to come.
You can jam or call, then jam turn.
With the preflop action of 7 players for 17, that's $119 preflop. Another $140 goes in before the action gets to you. That's $260 in the pot. You can't raise enough to get someone with 250 out of the pot.
When thinking about whether to call or raise, the idea is not to be scared of the draw but to deny them the right price to draw. In this case, with two all ins before you, someone is probably already in with a flush draw so letting another draw in behind you doesn't necessarily lower your equity.
This pot is so bloated from the pre flop action and the flop action before it gets to you, an opponent with only 250 cant make a mistake changing NFD and you can't raise them out.

this is fine, but your mentality should be wanting FD's to call, not get them out of the pot.

with a stack of $500, I'd think about raising to $100-$120. Small enough for FD to call a street=build a bigger pot, Then Bomb the turn if you want to chase them off. I don't know if I would do that or not,(I haven't found myself in that situation yet) but I have discussed that scenario with a couple of players before. Requires pretty solid knowledge of V I believe.

Dutch is right...when you are going 7 ways to the flop and the pot is already 60bb, flush draws are getting it in here all day. Shorties are not calling 10% of their stack PF to fold a flush draw on the flop.

I can't believe everyone folded though after a $20 bet, $43 all in, call, call. Some of these guys just put like 25-30% of their stacks in and then folded to your raise. You were definitely right to raise here when that many people have shown interest in this hand after the flop.
