I probably should've reraised on 3rd street, but what could seat 6 have other than a flush on 5th street given how the hand was played, even if clubs are somewhat dead? I decided to just take a free card when he checked on 5th street since I believed he had the flush. On the river, given that seat 4 was raising an apparent flush (or at least the threat of one), I didn't think 3 queens could possibly be good, because I would expect him to be calling and not raising if he had less than a flush.
