Daviddem, you hung around to play bikes HU? Good for you!

some notes on your hands:
AKs BB v BTN is the most standard stackoff ever esp. since I'd guess kiwi wasn't playing like a nit.

Do you have a reason for not 4-/5-betting JJ/99?

In 99 hand, it's a 4-bet pot and when bikes checks back flop/turn I'm guessing most of the time he is doing it because he has SDV, most of which you don't beat. I'd c/f all streets, but really, probably jamming pre is betting than flatting 4-bets OOP. You're not going to outplay him in that spot.
