Deep Stacks

[ChrisW]

I bet 500 on the end and got called by AQ.

BTW, one reason to think that Villian is not a crazy donk is that his bet sizes were appropriate to the texture of the flop. In my experience, when a donk randomly decides to run a pure bluff, he doesn't usually bet in a way that represents any certain hand (or range of hands). Of course, that's not to say that Villain won't bluff raise the river, but the flop and turn feel like he's playing poker, don't they?
