112 Checkout in Darts — T20 → 20 → D16
The 112 checkout uses a three-dart route through T20, 20 into D16. At this score, controlling the first dart is the central challenge — everything else in the route depends on where T20 lands. A clean execution through T20 → 20 → D16 leads directly into D16, one of the strongest finishing doubles on the board and a consistent closer under match pressure.
From 112, a miss on T20 has a clear preferred direction: toward 5, which leaves 107 — checkout T19 → DBull. A drift into 1 leaves 111 instead — the worse of the two outcomes by a meaningful margin. This is not something to aim for passively. The pre-throw routine should include a deliberate bias toward the 5 side, expressed in the follow-through direction rather than in any adjustment to the aim line. Consistent application of this principle across a match produces better leaves on misses, which reduces the number of visits needed to close a leg.
What separates consistent finishers on 112 from inconsistent ones is rarely the route they choose. It is the quality of the decision-making that precedes each throw. Taking an extra moment before stepping to the oche to confirm T20 → 20 → D16 as the right route, confirm T20 as the right first target, and confirm full commitment to the execution removes the reactive thinking that pressure introduces. The throw itself is already there — what gets disrupted under match conditions is the clarity of intent before the throw begins.
The focus on 112 should be on setting the route cleanly, not forcing an early finish. Patience at this score is a genuine competitive advantage. The most important moment in finishing 112 is not the throw itself — it is the decision to commit made before the throw begins. The dart responds to the mechanics of the throw. Keep those mechanics consistent and pressure becomes irrelevant to the outcome. The moment between stepping to the oche and beginning the throw is where pressure is managed. Use that moment deliberately — breathe, grip consistently, commit. Consistent finishing in darts depends on mental control as much as technique — and mental control, like technique, is trainable through structured practice.
This is the route that wins legs under pressure — strong first dart, elite double, no weak link. When the opponent is threatening, commit to this structure without reservation.
Route Comparison & Target Selection
Primary: T20 → 20 → D16
treble 20 (60), single 20, closing on double 16 — high-percentage close
Alternate: T20 → 12 → D20
treble 20 (60), single 12, closing on double 20 — high-percentage close
The primary (T20 → 20 → D16) and alternate (T20 → 12 → D20) close on comparable doubles — D16 and D20 respectively — and both offer a valid path to the finish from 112. The miss geometry on T20 is asymmetric — the 5 side leaves 107 and the 1 side leaves 111, so the preferred drift direction is toward 5. The distinction is in the approach. The primary is the standard route and should be used as the default. The alternate is the contingency for visits when the primary's sequence is not producing clean grouping — same close quality, different path, equally valid when the specific approach is working better.
The anti-target on T20 is 1. A miss there leaves 111 — the preferred miss is into 5 for 107.
Miss Geometry, Route Structure & When to Use the Alternate
No high-value triple has worse neighbours than treble 20. The 5 sits to its left and the 1 to its right — the two lowest singles on the board. From 112, drifting into 5 produces 107 remaining and drifting into 1 produces 111. The primary route opens here because the score structure demands it, but the miss geometry should inform how you approach the throw. A slight drift in either direction from 112 lands in a segment that scores between three and five times less than the treble itself. Treble 19, by contrast, is flanked by 3 and 7 — both higher-value, both more often leaving a route that can still close cleanly. The drift trigger for switching to 19 exists precisely because of this asymmetry: when grouping moves consistently below the treble 20 bed, the geometry of 19 becomes structurally correct regardless of its lower maximum value. In terms of the dart count and sequence, three darts are required here because 112 resists any clean two-dart path. The sequence runs T20 to open, 20 to position, and D16 to close — each dart serving a specific function in the structure. The risk that the three-dart sequence introduces is rushing: players who hit T20 cleanly sometimes accelerate through 20 and arrive at D16 from a weaker position than necessary. Slowing the decision-making between darts — giving each throw its own committed setup before the release — is what keeps three-dart routes running cleanly under pressure. On the alternate route decision, the alternate (T20 → 12 → D20) provides a different path to the close — through T20 to D20 rather than the primary's route through T20 to D16. Both routes close the leg and both arrive at comparable finishing doubles. The alternate is the contingency for visits when the primary structure is not producing clean results: a grouping issue on T20, a leave that favours a different approach, or a visit where a fresh sequence produces better rhythm than repeating the primary. The primary is the default; the alternate is the in-visit adjustment.
When and Why to Use This Route
This route is correct whenever this score appears. The decision has already been made — T20 into D16 is the route, and the job is to execute it. There is no tactical calculation left to do at the oche.
The strength of this route is that it does what the best checkout routes always do: solves two problems at once. It scores efficiently enough to maintain pace and finishes on a double forgiving enough to close under pressure. T20 handles the first problem. D16 handles the second. Neither dart is a weak link.
Why Players Miss This Finish
The most common pattern in a missed 112 checkout: T20 lands cleanly, 20 is rushed or slightly off, D16 is either unavailable or approached under recovered tension. The sequence breaks down in the middle, not at the close. Players who are aware of this pattern and deliberately slow their approach to 20 — giving it the same deliberate attention as the opening dart — close 112 significantly more often. The route is three committed throws, not a strong opener followed by two consequences.
The fix is specific: before stepping to the oche on 112, decide the full route, decide the preferred miss direction on T20, and commit to both before throwing the first dart. Players who make these decisions at the line rather than before it are making them while moving — which means they are made reactively rather than deliberately. A decision made before the approach is a decision that holds under pressure. A decision made mid-approach changes the throw.
Practice
Run T20 → 20 → D16 in sets of five attempts and track how many convert cleanly in two visits or fewer. That number is more informative than raw completion rate because it reflects whether the route is working or whether legs are being closed through recovery. A high raw completion rate with low two-visit conversion means the route is closing eventually but not efficiently — the visits are running long, which means first or second dart quality needs work. A low completion rate with decent two-visit conversion means the close is the problem. The metric reveals where to focus practice.
Include recovery reps in every 112 practice session. When T20 drifts into 5, the leave is 107 — practise that score until it feels routine, because it is the most likely leave after an imperfect first dart. When T20 drifts into 1, the leave is 111 — that one deserves practice too, because a leave that has never been practised becomes a source of hesitation in a match. Building familiarity with both miss outcomes means the visit continues automatically rather than stalling after a drift on the opener.
