Hit a 13 with Confidence ?
Here we examine the decision: As well I include the argument for the given action upon the 11, 12, 13 in this table as well as the ones elsewhere in this site for pages for the 8,9,10,11 and the 15,16. Links as well their they are assembled with their salient points,(that demonstrate the properties that have been used to compiled and acquire the Basic Strategy as it is used today, and how the count systems lend themselves to the utilization of these properties.Assembled with Single deck replacement attributes. that is as 52 cards 1 is removed. (as used) hence taken out of problem.. For ease of conversion the rules applied are that of six decks, disregarding those replacements, as we have discussed in 6-6 vs 2, that would apply. Hence, it should be appreciated that these replacement evaluations have less effect in six decks.

As you can see the margin for hitting 13 is extremely small. consequentially the count criterion for the change in the Basic Strategy is small -1, see here by the "Meld" of the four previous mentioned plus-minus counts and hence the factor that the Matrix Count is most useful in the margins for the 13 against the 4,5,6 are also small and you will have the middle cards population density exactly in mind when you make the daring decision to hit or even double the 13 ? no just kidding ? maybe not !.....
