I deal with a lot of people on a daily basis who make a lot more money than me. The first thing you have to do is never be amazed or in awe by it. Act like you could give a shit that he made $700k, I wouldn't even bring it up. Second thing is you can never feed into their ego, or they own you. Act unimpressed, and they'll try to impress you. Hopefully with this guy, that would have been some poker strategy other than "4bet bluff a lot".

If someone comes in acting like a know-it-all I try to ask them I question I know they cannot possibly have an answer to, or I ask them to hit a shot they possibly could not pull off. Then I own them, and they have to listen to what I have to say and do what I want them to do.
