Humm this doesn't sound like the Chan described by Barry Greenstein's site...
In the late ‘80’s and early ‘90’s, Johnny was the best no-limit hold’em tournament player in the world. Since then, he has used his tournament success as a vehicle to get himself involved in different business ventures. He is still a skilled player, but he plays very impatiently as if he is late for a meeting. He used to be very weak at limit poker, but he improved his limit game significantly in the late ‘90’s and early 00’s. It is probably surprising that I listed pot-limit Omaha as his best game, but I am going by results and his best results over the last few years in side games (and even in the WSOP) have been in pot-limit Omaha.
But his range here is ... Any two cards..
We must raise here with AKo.
We have a big skill disadvantage to him. We are out of position too. This is countered by our card advantage.
Bang it in preflop if he raises, re-raise.
