Facing SB all in, EP all in, MP all in, and action to me. I have the nuts on one board with a redraw to a 3 or a heart. Usually if its just heads up I think it would be a fold because you are fighting for half the pot and if you are up against the same hand you end up getting quartered. Looking at the equities I win 25% of the pot about 39% of the time chopping with player 3. 22% of the time I suck out with a 3 or a heart. So is this worth calling off? If it was only 3 way all in, should I just fold? Do I need KhXh with the 53 to stack off here?
