F-In River: $3/$6 UB NL

[Big_Jim]

Hero is sitting with about $650 or so. I just got stacked about an orbit or so ago when I re-raised about 20% of my stack PF with AA, and a guy flopped a set of nines on me.

I have played several pots since then, and have not had to show down my cards. It may appear as though I'm tilting.

Villian has been playing fairly well, and hasn't done anything too out of line. He has been caught bluffing a few times, but only in small pots. He has made a few very marginal call-downs on aggressive players.

I'm UTG + 1 with A[img]/images/graemlins/heart.gif[/img]A[img]/images/graemlins/spade.gif[/img]

UTG folds. Hero raises to $24. Folds to Villian on button who calls (Covers me). Blinds fold.

Hero .... ?

I have $436 behind.

Block bet?
Check/call a decent bet?
Something more drastic?

Thoughts on all streets appreciated.
