What the hell am I doing here?

[joker122]

Party 5/10


3 limpers and I complete in the SB with 9c7c.

Fop: 8c 9h 8s

I check, first limper checks, limper2 bets, limper3 calls, I call, limper1 folds.

Turn: Qd

limper2 bets, limper3 calls, I fold.

River: 6d

bet, raise, call.

why not just bet the flop? you have top pair, bd flush, bd straight...

or is this a case of reverse implied odds?

I'd probably check-raise this flop.

What would a check raise do for me here?
