Okay, this is probably wrong (I'll figure this game out SOMEDAY), but I'll take a shot.

First of all, Rover is an idiot for calling half his stack there. He needs to either go all-in or fold there. But he didn't so we work with what we've got. Farmist acts before you, so I would have liked to have seen whether they called or not. If so, I probably fold.

If farmist folds, it's a tougher call. I think you're DEFFINATELY beat at this point (if he didn't go all-in on the flop, I'm not sure I can see him pushing in on the flop if he didn't hit it), the question is how badly? If you think he's just got top pair (that would be my guess - if he had JJ he would have gone all-in before the flop, and I can't see calling half his stack with something like 89s), it might we worth a call just because you've got the chips and have a shot at knocking him out, but I think even if he does have top pair, he's likely playing AJ or KJ and you lose three of your outs right there.

Bottom line - I think you're probably in pretty bad shape here (I'm guessing you have 3 outs, MAYBE 6). The question is if you've willing to gamble and take a shot at knocking him out of the tourney. I probably fold it and wait for a better opportunity.
