Sky's the limit. What an opportunity if he has KK or A8! Don't worry about how long it takes, don't worry about if he has AK too. The dealer may keep your bets separate from his to simply a potential pot split. But if you do anything less than reraise reraise reraise reraise, there's something really wrong going on here.

As I posted somewhere else, I've seen a lady lose all her chips against a local rounder in a similar situation. Board Q J T 6 2 rainbow - they go all-in HU on the river. Both have AK, right? Well the rounder did. She flipped QQ and said "ship it!" ??
