23 checkout
In short
23 checks out in two darts under double out: S7, D8, for 7 + 16. If the double 8 lands in the single 8, 8 is left and still on: D4. And if the double 4 drops into the single 4 as well, 4 is left for the next visit: D2. With a single dart in hand, S7 leaves 16, so D8. Under straight out, where any segment can finish: S13, S10.

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.
