For example, if the dealer’s up-card is a 6, assume they have sixteen and might bust; in the occasion that they show a 10, assume they have 20 and you’ll have to play accordingly. The supplier acts after you’ve finished your flip, and the dealer must comply with fixed guidelines – typically drawing cards till reaching a minimum of 17 in hand worth.
