Donkey Test

Why is your question any different? If he folds then you win the pot, so don't you only care about which hand is best if he calls?

Edit: Well I should admit the question really confused me too and I had the same thinking - 88 is the only made hand, but with the least chance to improve and beat something he's calling with. QJ seems to have the most outs (barely) with the backdoor straight draw and you might not be reverse dominated as you would with AK against someone calling with AT, or who knows? Maybe you want him to call with AQ? I'm totally lost as to why you'd ever go all in with any of those hands and only $40 invested in the pot.
