Party 10/20 vs a very specific player. Do you alter your play?

calling the turn likely gets the same amount of money in the pot and doesn't cost you a bunch when your passive friend has 99. it' unlikely that he has 99, but it's not worth risking since you're gonna get the same amount in anyway.
the river is more debatable. I'd probably raise and hope that BB calls two cold with a reasonable ace or some other 3.
