One of the keys to beating the casino is knowing how large their initial advantage is against you. It’s important to know your odds on blackjack. Use this blackjack calculator to see how various rules affect the casino’s advantage. Remember that this is assuming perfect basic strategy. With Hi-Lo card counting, the player’s advantage goes up by about .5% for each positive true count. So if it says “0.50″, then the player will have an advantage starting at a true 1, a .5% advantage at a true 2, and a 1% advantage at a true 3. Conversely, the casino would have a 1% advantage at a true -1.
Note: If the output is negative, that means the player has the advantage off the top.
