There have to be winners and losers at everything, but, in the long run, casinos will always win against flat betters. Casinos would not exist otherwise

You are a statistician Erdal, you know that

Typical BJ may only be 2% (unless of course the casino has its own method of determining when reshuffling will occur) Roulette a whopping 5.2% etc.

But I think it raised an interesting point. A thread some time ago questioned the casino's future ability to determine when the remaining cards were in the players favor and call for immediate re-shuffle. What does gaming think about this? What is the difference between that and someone putting a 'flat' marker down in front of a player?
Surely its like 'raising the hold' on a slot machine, contrary to regs?? Am I missing something?
