### Deck estimations in blackjack

22 August 2015

When it comes to card counting in blackjack, you must be able to judge the correct number of decks remaining in a shoe to help determine the true count. To accomplish this, you need to recognize the correct size in the discount tray, study the stacks and practice. One method for learning these three tasks is to obtain 30 decks of playing cards. With 23 of the decks, create stacks as shown below and tie each with a rubber band.

Stack 1: 0.5 deck
Stack 2: 1 deck
Stack 3: 1.5 decks
Stack 4: 2 decks
Stack 5: 2.5 decks
Stack 6: 3 decks
Stack 7: 3.5 decks
Stack 8: 4 decks
Stack 9: 4.5 decks

These are your models; learn to recognize the size of each of them. Study them closely.

For this drill, take six decks from the remaining 7.5 and practice cutting stacks that equal the size of your models. Visualize the cards you cut as being in the discard tray. As you cut each stack and compare it with the appropriate model, mentally subtract that number from the number of decks in the game to compute remaining decks.

For example, if you cut a two-deck stack and there are six decks in the game, subtract 2 from 6 to compute remaining decks. If you cut 3.5 deck stack and there are eight decks in the game, subtract the 3.5 from 8 to get 4.5 remaining decks.

Do this drill until you are skilled in estimating decks played and remaining decks to the nearest half-deck (26 cards). If your normal practice session is one hour, you should devote 5 to 10 minutes to this drill.

It was designed to prevent card counting, but it never caught on with casinos or the public.
