Always hit a soft 17 (i.e. ace-6), split aces and 8s, double down on 11, and stand on a hard 17 (or greater). Never split 5s or 10s and never stand on 12 through 16 if the dealer is showing a 7 or higher. Never play cards when you’re drinking. Never believe you’re on a winning streak and never over-bet or make foolish plays. Never play for extended periods of time without taking a break, getting a drink of water, eating a snack, or simply stretch your legs.
