the way i see it after the all in especially knowing the chipleader is behind u, u have two plays fold or all in, YOU CAN NOT EVER CALL IN THAT POSITION ITS A HORRIBLE PLAY. You also should know how the players at the table play since it was a small tourney and there is only four left. After the player made that move behind you, you can go either way but I would put the rest of my chips in and hope if I lose to the big stack hopefully he beats the small stack as well so I take third. Best case scenario I win a huge pot. I would probably have folded the 88 over the all in there anyways, cause I would figure its the bigstax job to call if he is left to act, and also you figure that going in you likely arent any better off then a coinflip, and maybe a lot worse off then that.
