Wow, I don't know about folding the KKK hand, but you may not have know how agg he was. Nh, villain.

On the OP, I like the bluff play. The worst hand that is a likely call from your villain as described is KK. I think it looks like you have AA and are defending against the draw to scoop a nice pot now. If he had a monster and didn't raise you, curse the poker gods of electronic deck shuffling.
