600nl, JJ UTG vs sb

[evil_twin]

This is my first hand post, this may well be entirely uninteresting. I've been wondering about it all day though so I decided to post and get some thoughts.

Second orbit, hence no reads. SB played most pots in first orbit though, folding mostly on the flop to aggression. We're 7 handed, table seems to be breaking up.

Blinds $3-6. I'm(591) dealt JJ UTG, I open to $24. All fold to SB(650ish) who calls. BB folds.

Flop: 4[img]/images/graemlins/heart.gif[/img] 6[img]/images/graemlins/club.gif[/img] 5[img]/images/graemlins/diamond.gif[/img]

SB leads for $25. I call.

Turn: K[img]/images/graemlins/spade.gif[/img]

SB bets $25 again. I minraise. SB quickly calls.

River 7[img]/images/graemlins/spade.gif[/img]

SB rapidly pushes $550ish. I fold.

Pretty obvious fold. What interests me is what sort of hands the SB would make this play with.

My turn minraise (clearly representing AK or better) defined my hand pretty well, hence he can push on any scary river and probably knock me off the hand. Having said that I've only just sat down and have no notes on the villain so I doubt he has any on me either. My preflop raise + turn minraise looks strong so he must put me on AK, an overpair or a set. My feeling is that he wanted a call on the river. There are donks who will call this bet on the end with AA or a set.

Villains river play is odd though, I've been wondering about it all day. Flopped two pair or set makes no sense to me, since that is NOT a river to be pushing on. Hence he has the straight (perhaps flopped it). However, in this case why bet so much on the river, he probably could have extracted some money from me if I have AK or better.

In which case, did he read the situation perfectly and outplay me? What could/should I have done differently?
