That's hilarious! Showing his cards with money behind. Wow.

It's probably not a mistake. However, I've found that players have to be fairly bad to stack off vs a strong lead into them like this. They've all read Super System, and unless you lead big often and turn over draws, they're scared of a set.

He's just weak tight and knows you know he has AA. You might want to get a little creative in the future. Underbet lead into him if he doesn't know you're any good at poker. He'll put you on a draw and try to protect his hand -- probably put in a huge pot committing raise.
