Rare postflop play, level 3

[kyro]

25/50 blinds. No read on main opponent, which means I don't recognize him as a solid player, nor has he done anything too donkish.

Folded to Hero(~950) on the button with 9[img]/images/graemlins/club.gif[/img] 7[img]/images/graemlins/club.gif[/img]. I make it 150 because I'm special and clever. SB calls.

Flop: AQJ with 2 clubs.

Check. I bet 250. He calls. Great.

Turn is offsuit K.

Check/check.

River is offsuit K.

I fold to his all-in push.
