It doesn't make sense to me. Yes at .3 kelly that would be 887 units, but at full kelly that would be 266 units. That would mean at full kelly you would only need $2660. There is no reason to have 10k at all for a $10 unit. If you want to play the high risk at full kelly you don't need a real big bankroll but it better be replenishable, because you have a 50% chance of losing it. And if you want to be on the ultra conservative side of kelly, go with .3 and you still need less than 10k at $8870.
As for the playing in the high roller room, sure you can play bigger in there, but you can't play a conventional big player call in game there because of no mid shoe entry. Its okay for some advanced techniques, but I was under the impression from previous posts that you did call in team play. As far as playing with celebrities go, I've played with more than my share, hell Michael Jordan never even raised his bet over $5000. So if all the attention is at his table while I'm sitting there, and I was betting more than 3 times his bet for my max, I think thats just inviting red hot burn your house down heat. Of course its a different story if you are working for them and signaling them what to bet, than you're just betting table minimum and all eyes still remain on them.
