Theory and Reality

Card counting can create a mathematical edge, but real play still has limits such as table rules, penetration, table limits, speed, bankroll, and psychological pressure.

Practical Factors

• Deeper penetration usually makes counting more valuable; shuffling too early reduces usable information.
• Bad rules can consume the edge; for example, 6:5 blackjack is usually very unfavorable.
• Even with a positive edge, many losing hands in a row can still happen in the short term.
• Casinos may refuse service based on play patterns.
