3 Flush probably H/U

[SA125]

This is along the lines of Istream's common situation post. You're in a tight game where the high card just about always raises and drags the antes. Aside from the fact that the game stinks, this one spot has me thinking.

The board is K high. A fold or two to a tough player with the K and he completes. It's 50-50 whether he has K's or not. You have a 3 flush Q up, all live, with all low cards behind that are probably not playing. Do you fold, call or re-raise knowing you'll probably be h/u?

I think it's a fold because he'll keep the pressure on, even if stealing. If by 5th I show no improvement, I'd likely have to put in a bluff raise and a bet on 6th to win if he was stealing. I don't think a call here makes sense if you're likely to be h/u and folding unimproved on 5th.

I didn't specify a structure because I'm not sure it matters. Any thoughts appreciated.
