Suggestions on a plan for this hand?

7 players
Hero (MP, $110.75): Q J 9 7

UTG straddles for $1 6 players call for $1, then UTG raises it to $8, Hero calls, CO calls, button calls.

Flop ($35 in pot): 10 8 K

UTG leads for $21.
What is my plan here ($102.75 in my stack, and all 3 villains cover me)? A repot nearly puts me all-in with 2 to act, and I haven't made a hand yet, plus my outs aren't entirely clean.

If I call, I kind of expect at least one caller since the flop seems to work well with people willing to see a flop for $8 in a .25/.50 game.

So, give me your best advice on how you play this flop for my hand, please!

Pre is meh regarding calling the pot raise imo. Since it's live I guess I call too because lol_20_hands_per_hour.

Flop step 1 is at least don't fold. Repotting probably rarely puts us in good spots but it could push out medium-sized flushdraws which is nice for our equity. Probably a somewhat clear call though. I mean that's what, a 20 card wrap? It's nice even with the flushdraw out there. Bare wraps in multiway pots with flushdraws out there can often put one in trouble but that wrap is too big (that's what she said)

Thanks, Loctus. That's pretty much what was going through my mind.

Hero calls $21. CO calls, Button folds.
Turn (3 players; $98) T 8 K 7
UTG checks. Hero shoves all-in $81.75. CO tanks for a full minute and calls. UTG folds.

Yeah that's a tough hand to be the first person to call the pot-sized raise with. You might be getting a lot of players calling behind you, too, and that's probably a better hand to go against aces heads up with. You don't want to go against 9/10/j/q, 9/10/j/k, 10/j/q/k, 10/q/k/a and other type hands that will often dominate your potential wraps and have higher flushes on top.

11 outs to turn the nuts, 3 of which give you a re-draw to the diamond flush. 4 more outs which give you 2nd nut straights on the turn, 2 of which also give you a re-draw to the diamond flush. That sounds like a good reason to call.

Not sure how the potting equity works out. If an ace-high heart flush in one hand and a set from another call your re-pot, you're ahead of the flush draw but behind the set. Unless I'm mistaken here, your best chance with the re-pot on the flop would be if you could somehow get heads up, which isn't a guarantee obviously. A call seems right.

FYP. Thanks. Agree with shoving the turn as shown above?

Oops sorry, you're right. Had the suits mixed up. Yes, I meant your re-draws to hearts not diamonds.

Can't see how you wouldn't shove the turn. You're getting value from any hand except for a person with the same straight with the diamond flush re-draw. I don't think you can realistically worry about that very often as it's highly unlikely considering you hit a 9/j straight. You're ahead of a person holding both a set and diamonds draw and you want them to call.
