Multiple Deck Blackjack Strategy Chart

The Basic Strategy Chart for Multiple Deck Blackjack shows the correct action, based upon mathematical probability, for all situations when involved in the standard game with four or more decks in play. It contains fourteen differences from the Single Deck chart, requiring the user to play a slightly tighter game.

Note that when the House Rules allow doubling down after a split, the chart should be modified to allow for slightly more aggressive action, splitting pairs of 2s or 3s against he dealer’s 2 or 3 up, splitting 6s facing a deuce, and 4s against a 5 or 6.
