With perfect basic strategy, blackjack has a house edge of roughly 0.5%, making it the best table game in most casinos. Without basic strategy the edge balloons to 2-5%, so learning the chart is non-negotiable if you want to play seriously.
You and the dealer each get two cards. Your goal is to beat the dealer by getting closer to 21 without going over. You can hit (take a card), stand, double down (double your bet for one card), or split pairs. The dealer must hit on 16 or less and stand on 17.
Basic strategy is a mathematically derived chart that tells you the optimal play for every possible hand versus every dealer upcard. It accounts for every combination and reduces the house edge to its theoretical minimum. Memorize it before you sit at a real table.
Card counting is not illegal, but casinos can and will ask you to leave if they suspect you are counting. It requires significant practice to execute under pressure, and most recreational players are better off perfecting basic strategy first.
