Dear lord, what is seat two doing on third???

Anyway, if it is common to have multiway pots like this for any number of bets I think it would be safest to throw the hand away. Its a one way hand that becomes difficult to play against multiple opponents.

Once you're involved though its hard to play differently. A flush on 6th is a posibility but with the number of dead diamonds a low is more likely (this also illustrates a problem if you do get heads up with the Ace showing, you don't know if he's low or high which puts you at a disavantage).
