Adjust The Rules. Basic strategy is a mathematically calculated set of decisions that can help you win more at blackjack. The Blackjack Basic Strategy Engine above provides a simple way to memorize a variety of different profitable decisions, such as when to split, double, surrender, hit, or stand.

This unique system is an incredible resource for any serious blackjack player who needs to calculate the strategy for any game they encounter.

When you find yourself with a pair, you should check your basic strategy card to see if splitting is advantageous.
