I'm thinking that a bet of something like $90 here might be the highest ev play, because we're trying to induce some strange call from *both* players. If it were heads up I'd be more likely to just jam.
Ultimately it's a question of whether the EV of 1 player calling a big vbet outweighs the probability * payoff of both players calling a smaller bet. Only you will be able to estimate those variables.
Pot is $270. Remaining stacks of villains are $265 and $315. I find it really weird that two opponents have decided to come all the way to the river on this board, so 99 probably shows up here a decent amount of times. But obviously we're not folding cuz even a smallish $100 bet that is raised we'll have to call (we'll be getting well over 3:1 here).
Someone else has a two and is worried about their kicker, but they can't fold. All-in, imo. It's not even much of an overbet (less than pot sized vs one villain, and just a little more than pot sized for the other villain). Plus, if they're calling a 2/3 bet of $180, their chances of calling a PSB bet are only slightly worse (but obviously way more +EV for us).

I'm thinking both of these players (or at least the second caller) would have to be horrible in order for this to work; I can't remember the last time I saw two reasonable players call biggish (not necessarily in terms of size, but $$$) on the river, and with this board I think it's even less likely (on an unpaired board I could see multiple players calling with two pair, but not here).
@GG: True. To expect 2 callers here even to a small bet does assume that villains are horrendous. There are tables/table dynamics which make it feasible, though : the table I played on last night certainly was that way.
All I'm saying is, I wouldn't rule it out as a possible line. As mentioned, jamming is also an acceptable line.
