Blackjack betting spread: why do casinos care about variance in your bets.
Every time I ramp up my bet sizing in blackjack, the pit bosses start circling like sharks. I get that they don’t want people counting cards, but why do they get so touchy about players just varying their bets by more than 1 unit? I’ve noticed even with no obvious counting moves, just spreading my bets on a whim sometimes draws heat. Is it purely about minimizing their risk from advantage play, or is there more to it? Like does fluctuating your bet really impact their bottom line that much, or is it more about them not wanting to deal with swings? Curious how everyone else thinks about this.
