Throw: Double 5
(D5 | 10)
Option: Single 2, Double 4
(S2-D4 | 2 – 8)
Lots of players don’t like Double 5. It’s hard to be aggressive with it because a Single 5 leaves you with an awkward score of 5 remaining. That said, if your opponent is on an out, you’re better off being aggressive with the first dart than the second. If you miss outside with the first dart and adjust too much and hit a Single 5 with the second, you’re screwed. If you hit the Single 5 with the first dart, you still have two darts to work with.
As for the option above, it’s not recommended. You should be able to hit any double on the board. Learn to hit the Double 5. However, if your opponent is still above 130, you do have time to convert the Double 5 to the friendlier Double 4.
If you started the round with a score of 20 and hit Single 10, Single 5 with your first two darts, consider busting with your third dart. You can’t get out this round and you may prefer starting the next round with 20 rather than 4 (if you hit a Single 1 with your third dart). (I aim at the Treble 16 since everything around it will bust a score of 5.)
