Should I have slowed down sooner with my AA?

[Thebram]

Now I hadn't been at the table that long, but I had taken a pretty big pot away from MP2 in an almost fish-like manner just a few hands earlier. Since then, I had a slight feeling he was tilting a bit.

Even so, does it seem like I was too in love with my hand?

I can't believe the 8 helps him, but should I have gone into check-calling mode already, after he capped the flop?
