Never played poker in a casino but one New Years Eve I played drunk with £100 just after midnight, within
5 mins I had built it up to £600 and 5 mins later I had lost the lot including the £100 I started with. so £600 is
the most I have ever had in front of me at a poker table if not a cash table.
I've sat with between $480 and $540 a few times when I used to go to the casino to play live cash games. It's not a lot of money but it was a double up and a few smaller pots won in our $1/$2 Game so I was happy.
I think a cool question is how many Big Blinds have you sat with, anyone can buy in for the table max, but it takes skill to stack well beyond that consistently!
