Congrats, You Have Already Arrived.
If one wants to play full Kelly and burn through casinos like a meteor one can. What can possibly happen? One could have some modest negative variance of -$250,000 and then get barred from multiple casinos. How will the OP feel after losing -$250,000?
The OP does mention casinos in 5 nations. One would need to think internationally to spread their play enough with a huge bank. I would feel most comfortable playing the US, Canada, Western Europe with perhaps Bahamas and Aruba thrown in. Would anyone add to this? One would need to understand laws and regs of internationl money movement.
The OP mentions having skills beyond counting. One would need other skills to bet very big for any reasonable length of time. A general rule of thumb can be the larger the bets, the more you need to get away from straight counting. One issue is if one feels the need to use a lot of camo they may eat into the potential profit of those big bets and are just on a variance roller coaster vs playing smaller but more aggressive. A classic example is spreading 1 to 4 in a high limit room vs spreading 1 to 8 on the main casino floor.
I am going to assume this bank is still close to the OPs total wealth because he does not feel he has enough to retire, yet. Given this assumption he should consider betting 1/8th semi-resizing kelly. This allows the player to not have to worry about negative swings, he will probably never need to resize bets down on losses (semi resizing). His NO will be very low compared to daily resizing. This would also allow much of his bank to be in other income producing investments that protect the bank, perhaps bond funds.
If one takes a broader look at casinos one could play in then double $400 or $800 start becoming the top bets, so very large banks are forced to be conservative due to table max's. Game and casino selection also change, with large banks the ability to bet big is often more important then quality of game, this would definately hold true if betting 1/8th kelly because variance due to game quality is greatly reduced.
Already arrived:
The OP could already look at himself as retired and he travels and plays cards a few hours a day for recreation.
What could be potential downfalls for an exciting, rewarding life?
drugs
women-can't spend to lavishly on them
theft
gambling, non AP play
high expenses
barring
To sum up:
BET 1/8TH KELLY, REST OF BANK IN LIQUID INVESTMENTS, MOVE AROUND, LIVE A FRUGAL LIFESTYLE, LOWER YOUR EXPECTATIONS
