Not all tables are equal. High rollers look for bounceless or "dead" tables. A table with too much "spring" increases randomness, making dice influence nearly impossible.
Only "Buy" the 4 and 10. For high stakes, ensure the casino only charges the commission (Vig) on the win, not the bet. This significantly lowers the house edge compared to placing the 6 or 8.
Never put more than 4% of your total session bankroll at risk on a single shooter. High rollers survive through "Time at Table." If you bet too heavy too fast, variance will wipe you out before the heater starts.
High-stakes play generates massive "Comps" (free suites, meals, travel). Factor these into your ROI. A session that breaks even but nets $1,000 in travel value is a profitable session.
