A Set, a Donkey, and a Passive Villain

[Tilt]

All friendly, helpful, and politely delivered comments are appreciated.

Reads: I have been there 3 orbits, and entered and won one pot with no showdown. Villain 1, whom I will call Donkey, has been losing alot of money at the table since I have been there by raising every other hand and making pot sized bets to the river with second pair. Somehow when i arrived he was at $200 stack but has fallen precipitously since.

The other villain I have seen alot of and have a good read on him as very passive. If he is raising at all watch out, but his calls indicate weak pairs or draws.

Donkey bets $16, Hero calls $16, Passive villain calls $16

Its a great flop for me. But I don't want to chase the passive villain out of the hand or let the Donkey off the hook. I expect the passive villain to call here with any pair, but not if I raise. And he will call the Donkey down with even a strong second pair. So I call in the hopes that I can get them both committed and risk the draw. Mistake?

TURN (Pot = 69) 3[img]/images/graemlins/spade.gif[/img]
Donkey bets $16, Hero raises to $40, Passive villain folds, Donkey raises all-in to $85, Hero calls.

I bet to induce the all-in, but am still hoping the other villain calls. Anyone just call here?
