The house edge for aspect bets is mostly larger than for the blackjack recreation itself. Nonetheless, facet bets can be prone to card counting. A aspect count designed specifically for a specific aspect bet can enhance the participant’s edge. Only a couple of facet bets, like « Insurance » and « Lucky Ladies », correlate well with the high-low counting system and provide a enough win price to justify the effort of advantage play. Under the « Reno rule », doubling down is simply permitted on exhausting totals of 9, 10, or 11 (under an identical European rule, only 10 or 11). The Reno rule prevents the participant from profiting from double-down in these situations and thereby increases the participant’s expected loss.
