Is the river a dream or a nightmare?

[aggie]

MP is a very good 2+2er (adsanman) and is ~25/12. He's aggressive and certainly capable of making some moves but when allot of money goes in he usually has the best hand. His read on me is probably that i pay him off way too much. I don't have much of a read on SB but he seems donkish...

Any thoughts on the river? Should i be raising this turn?
