If you're new to blackjack, then the gameplay must look very simple. But scratch the surface and you'll discover it's deceptively so. Blackjack at the casino is the one game where skills can bring the house edge down far enough into your favour that you can make steady and profitable sessions every time you play. But for this, you need a deep understanding of the card probabilities. For this, it's good to memorise a blackjack strategy chart. But you'll also need to know how to count cards.
