remainder of the K-O Preferred strategy matrix is
presented on page 85. How do you use this sparse-looking
In reality, the strategy is still very similar to
the basic strategy. As mentioned, of the 270 basic
strategy plays, a mere 18 exceptions (those with entries
denoted A, B, and C, plus insurance) exist in the
Preferred K-O system. This can be contrasted with
the Hi-Opt I or High-Low systems, which in full form
contain 50 to 150 matrix decisions to memorize, each
of which can take on one of 13 or more integers. Ouch!
The similarity allows us to present only the portion
of the Preferred strategy matrix that's different
from the basic strategy. All splitting decisions (not
shown) and soft-hand decisions (not shown) are made
exactly in accordance with the basic strategy. For
the portion of the matrix that is shown, all entries
with a blank box also revert back to the basic strategy
play. For example, we stand with a hard 14 vs. a dealer
2, just as basic strategy prescribes. We hit with
a hard 16 vs. a dealer 8, again just as before.
The remaining 17 entries, denoted with A, B, and C,
represent the complete Preferred Strategy matrix.
For these plays, we follow the legend. For example,
if holding a hard 16 vs. a dealer ten, we stand if
the running count is greater than or Play all soft
hands, pairs, and blanks according to the basic strategy.
Take insurance at running count >_ 3.
Hard 12t Value = stand if RC ? Value; otherwise hit.
1 11 Value = double clown if RC >- Value; otherwise
equal to the value of B; otherwise we hit. Similarly,
if we hold a 10 vs. a dealer ace, we double down if
the running count is greater than or equal to the
value of A; otherwise we hit.
For K-O, regardless of the number of decks in play,
there will always be the same 17 strategic entries,
each of which will take on one of only three alphabetic
designations. The only difference is the values of
the three designations. The rest of the strategic
matrix is exactly identical to the basic strategy.
The table below summarizes the matrix plays, and may
aid in their memorization.
The values for A, B, and C should look somewhat familiar.
The A values are the pivot point (always +4). The
B values are the key counts. The C values are the
IRCs, omitting those for 6 and 8 decks. What could
be simpler to remember?
