Doubling and Double Approaching
Strategies
Double Approaching Strategy
Double approaching strategy is based on the concept of avoiding
a bogie leave such as 159,162,163,165,166,168 or 169. The point being that it is
better to score 1 or 2 points less to leave a finish. For example, a 136 score
with 306 left will leave you on 170 which is better than scoring 140 to leave
166!

only use bull strategy when opponent is ahead or tied
** only use double approaching strategies when opponent is at 315 or less |
Doubling Strategies
Doubling strategies are based on the qualities of the doubles.
There are three points of interest when considering double breakdown strategy.
 |
Because we often use triples to arrive at a double, doubles
are broken down into three categories which I will designate as Group A,
Group B and Group C doubles. These are important because given any number it
is only possible to arrive at doubles within one of these classes by first
hitting a triple.
|
|
The number of times a double breaks down to an even number
when missed on the inside single pie. This is important because it reduces
the number of wasted darts required to make the score even.
|
|
The larger numbered doubles are in general better because as
you break down to smaller numbers you can bust more often and ultimately
lead to double one which can no longer be broken down.

These groups and relative strategies will be essential in selecting the best
breakdowns. There are however, other important criteria when considering
breakdowns such as darts available and opponent's score. As a result, the
breakdown charts will have several columns for missed shots and other
considerations. I will also break the charts down into categories. In
parenthesis in the headers are calculated percentages for these strategies based
on typical pro level precision.

These can only be done by using double bull. So there is very little choice
here except that one could play T20-T18-DB on 164. It should be noted that one
does not need to play the finish if the opponent is not on a 3 dart breakdown. Statistically
it is better in this situation to setup a good double for the next shot such as
double 16.

This strategy is statistically better for 3 dart outs than the T-T-D
strategy. However, if the opponent is above 120 then it is likely better to play
the T-T-D strategy and play for a 6 dart win. In this case T20-T17-D12 and
T20-T16-D12 is suggested.

Notice 125 is left out as it has the disadvantage of 128 and 129 of no 2nd
option, but has another strategy using bull which is weaker than the 122
percentage yet stronger than the 128 percentage.
Also, these bull strategies are only statistically worthwhile if the opponent
is ahead in score. Otherwise, T-T-D strategy pays off. On 122 with 6 darts it is
worth while to play bull first - DB-T16-D12/SB-T19-D20.

6 Dart strategies should be used when the opponent's score is
above 120. Using S-D-D strategies are risky and should only be used when the
opponent is almost sure to finish next shot.
Many players believe that B-S-DB is a better strategy for 91-95
scores, but this is false. Percentages for that strategy is only 27.6% - not
even comparable to the T-D percentage.
