Just call with a straight flush?

[Gamblor]

the title alone should make the board obvious, but here goes.

30-60 live.

I have 87cc in the BB, there's an MP raise from a solid player and a donk cold calls in LP. I throw out a quarter and a nickel and we have a pot.

flop comes Qc Tc 9c. nice flop. I check, PFR bets, donk raises, I call 2 cold (planning to raise the turn on any safe card), PFR calls.

turn comes (Qc Tc 9c) Jc. I change my mind and come out firing. PFR raises, button calls 2 cold, I 3-bet, PFR calls, button suddenly caps it. I call. PFR calls.

river bricks off. What's my river plan?
