39 checkout

In short

39 checks out in two darts under double out: S7, D16, for 7 + 32. If the double 16 lands in the single 16, 16 is left and still on: D8. And if the double 8 drops into the single 8 as well, 8 is left for the next visit: D4. With a single dart in hand, S7 leaves 32, so D16. Under straight out, where any segment can finish: T13. Under master out, where a treble can finish: T13.

When a dart strays

A missed treble or double often drops into the single of the same segment, and a missed bull into the 25 around it. Here is what that leaves, and what comes next.
