Guess my opponent's hand

[34TheTruth34]

I'm almost willing to offer a prize, just because I don't think anybody could guess what hand my opponent had here. But I'm too cheap. [img]/images/graemlins/frown.gif[/img]

It's 10-20 and I'm in the big blind with 8 [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img]. My opponent is in late middle position. There are five other players in this hand, three players between us and one on the button after him. He is an older guy who appears to be a reasonable player. I haven't played with him long, and I can't remember him showing down many hands. He hasn't played many, hasn't raised often, and hasn't been called on the two or three occasions where he bet the river. I'm guessing he's about even for the session, maybe up a little.

The flop is 8-5-3 rainbow. I bet out and get 3 callers and he raises. The player after him folds and I make it 30, folding all the players between us. He calls the 3-bet. Heads up.

Turn K, I think the board was still rainbow. I bet and he calls.

River 6. I get "that" feeling and check. He checks behind.

Guess what he had?? If you wanna comment on how I played it, go ahead and do that too. Do you like the flop 3-bet? Do you bet the river? Let me know...
