Preferred Matrix

In this representation, it's fairly straightforward to see what's happening. Each of the A entries is mentally replaced by the pivot point. Likewise, B entries are replaced by the key count, and C entries by the IRC. Let's take a look.

If you're playing in a standard IRC 1-deck games, then each of the A entries is mentally replaced by the value +4, each of the B entries is replaced by +2, and each of the C entries by 0.

Or consider a 6-deck games with the standard K-O counting scheme. Again, each of the A entries is mentally replaced by the value +4. Here though, entries denoted by B are replaced by -l, and C entries revert back to the basic strategy. You may have been noticing that most of the plays are accounted for under A. This comes about for two reasons. First, the value of A (+4) is equal to the pivot point, which is the point at which we have reliable information on the remaining deck content. Hence, it's here that we are in the best position to make the appropriate strategic deviations. Second, we will have large wagers out when the count is near the pivot point. Clearly, making the best play is more important with a large bet at stake.

As we've been discussing. some plays are more important than others. Readers who don't want to memorize all 1 R Preferred plays should consult the table on page 89, which prioritizes each of the plays according to gain in expectation.33 Following the table is Figure 5, which charts the cumulative gain from each of the strategic plays for our model. We have enumerated the plays in accordance with the table.
