Big river decision OOP deep. » Medium Stakes No Limit Discussion

Ok so i've just sat down on PokerStars new lovely deep tables. Ive been sitting for only a few minutes when the hand in question comes up.

I opened up 4 tables and got heads up with the player im geting involved with on 2 of them but we havent goten into any big confrontations or showdowns yet on the HU tables. I was able toi gather that he seemed to be 3beting alot out of possition 250bb deep.

We did however play a big pot on the other running 6-max table from wich I was able to gather some information.

Here is the hand we played prior to the hand in question:

So what is my river play here? very curious as to what other people think about a spot like this.
There is about ~$320 left in play

On a sidenote I would like for someone to tell me how to convert the handhistory text into those cool card pictures etc. Ty!

This is a bad river - but more because you are likely to lose your market instead of your hand.  I think he is going to be able to fold everything he had after that ugly card.  Therefore, I think your best line would be to check the river and hope to get shoved on by a bluff.  I think you are more likely to win the rest of his stack that way than by shoving and getting called by worse.  You are never ever getting away from your hand against Deano, so you are losing your stack either way if he has AA.  So we only need to consider whether you will win the rest of his stack more often against worse hands more often by checking or by shoving.  I think checking is the play.
