Results:
Hero had K, J (flush, King high).
MP1 had 10, Q (three of a kind, Queens).
Outcome: Hero won $20.12

It was so obvious he'd hit the queen. The only thing I was worried about was if he'd paired his kicker.
Surely he must have guessed I'd made the flush?

Because I had 2 outs to a better full house than him, and 9 outs to a flush to win.
OK, I wouldn't say I had the best odds with having to call 3.35 for a total pot of 10.05 (3:1 PO vs 4:1 win odds?) but I knew if I hit then the end payoff would be worth it because he was going to throw the rest of his stack in no matter what.
