River J [img]/images/graemlins/club.gif[/img] 4,800 in the pot, Villain has 1,540 left and Hero 1,790

Since we are on the bubble and SurfChick has an M of 4, is value betting the river positive tournament equity? The only hands I'm really worried about are 77, 22 and KJ and I suspect almost any other K will pay me off. Is that too optimistic? Would you value bet, and if so, how much?

push turn.

More on the flop so you can stick it in on the turn. I'd still shove the river and expect to get paid by every king and possibly worse.

900 on flop, shove turn. as played, shove river.

Despite Villain being typically loose/passive, is there any reason to think we're beat here and should maybe slow down?

[Loxodonta]

More importantly, will the last bet be called often enough by a worse hand to risk an otherwise healthy-ish 1,800 left in chips?

[pdiggz]

I would guess he shoves KJ or any 2 pair on the turn. So, I can't see how you are beat here.
