Big D, I agree with your posts, however I'm not sure about this:
The rebate is always given on an amount of play that insures it does not create a positive expectation situation.
You have some knowledge of this or is this just something that you would think they would do?
This particular comp is a very old one, and is very well understood by the industry or at least the parts that will take high stakes table game action. Generally when a whale approaches the casino, the "courtship" goes something like this:
- whale expresses his interest in playing game X at stakes Y and asks for a comp
- the house, as a measure of good faith, extends a room, food and beverage comp (known as "RFB" in the industry) to get the whale in the door.
- ground rules are negotiated - min and max bets etc. In the case of blackjack at these stakes those ground rules would effectively neuter conventional counting through a small gap between min and max bet.
- the house expects to see some play in exchange for the RFB comp
- during that play, the house evaluates the whale's play using both computer software and their own blackjack expert/card counter. The result of this is an estimation of the house edge.
- the whale requests a rebate comp (20% or whatever)
- based on knowledge of the size of the house edge against athis player, the house can compute how long a run the rebate has to be over to avoid a positive expectation for the player. There are pre-computed tables for this that the high stakes boss should have handy (or have memorized, more likely). Based on that the rebate comp is offered, valid only if the player plays for some number of hours/days of play (or possibly if the player hits some very large loss limit before that).
- the house computer and blackjack guy continue observing play to ensure the player hasn't suddenly improved and to keep and eye open for cheating.
While high stakes table game sophistication is not super-common in the casino industry, no casino that lacks it will offer those stakes.
