10/20 Deep...Weird spot

[whitelime]

Haven't been playing much lately w/ school but somewhat interesting hand came up. Villain is unknown on a small site. I have a ridiculous image. I got aipf w/ AT and AQ for stacks in the past 10 minutes. Haven't tangled much with villain other than RR him once where he folded.

4500 Eff stacks.

Villain opens in CO to $80. I just call AQo in the BB. Flop K [img]/images/graemlins/diamond.gif[/img]Q [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/spade.gif[/img]

I bet $400, he raises to $1150...I ?

Thoughts on my initial river bet and jamming over the top?
