interesting hand

[turnipmonster]

I wasn't in this pot, but I thought it was interesting. I apologize for the inaccurate board descriptions, I just don't remember.

5-5 game, EP (2k) limps, MP (2k) limps, lots of other people limp, flop is rags with two diamonds, I think ten high. EP (who is overagressive and seems to be steaming) bets 50, MP calls and everyone else folds.

turn is a brick, check check.

river is a diamond. EP bets 450, the pot is around 150. pretend you are MP, and you have 5d9d. what's your move?
