115 Checkout in Darts — T20 → 15 → D20
At 115, the leg is decided by the quality of the opening throw more than any other single factor. The route — T20 → 15 → D20 — is built to convert that first dart into a clear path to D20. Players who finish 115 reliably treat the opening triple as the highest-consequence dart in the visit, not the double — because the double becomes straightforward when the approach is controlled, and becomes genuinely hard when it is not.
From 115, a miss on T20 has a clear preferred direction: toward 5, which leaves 110 — checkout T20 → DBull. A drift into 1 leaves 114 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 115 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 → 15 → D20 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.
Tension changes the release point. A tighter grip means the dart leaves the hand later and lands lower. That is the miss that pressure creates, and it is preventable. Slow the approach down, not the throw. Walking to the oche deliberately creates time to settle. The throw itself should be exactly as fast as it always is. The gap between practice performance and match performance on 115 is always a pressure gap. Closing it requires training the pressure response, not just the throw. On 115, the pressure is visible — the opponent knows a finish is on. The players who close it ignore that fact and focus entirely on the process. On 115, the only difference between practice and match play is the number of thoughts between stepping to the oche and releasing the dart. Fewer thoughts means a better result.
Triple start into an elite double is the strongest structure under pressure. Commit to T20 and trust D20 — this route holds up when it matters.
Route Comparison & Target Selection
Primary: T20 → 15 → D20
treble 20 (60), single 15, closing on double 20 — high-percentage close
Alternate: T19 → 18 → D20
treble 19 (57), single 18, closing on double 20 — high-percentage close
Both routes close the leg through comparable doubles — D20 on the primary, D20 on the alternate — making this a choice of approach rather than a choice of close quality. The miss geometry on T20 is asymmetric — the 5 side leaves 110 and the 1 side leaves 114, so the preferred drift direction is toward 5. The primary (T20 → 15 → D20) is the default. The alternate (T19 → 18 → D20) is the adjustment for visits when the primary's opening sequence is not landing well. Neither route is a fallback — both are deliberate choices for defined circumstances.
The key miss geometry: 5 leaves 110 (workable), 1 leaves 114 (harder). Bias toward 5.
Miss Geometry, Route Structure & When to Use the Alternate
Treble 20 is flanked by the weakest neighbour pair on the board — 5 to the left and 1 to the right. Those two segments are the lowest-value singles in darts, which means any drift off the treble from 115 costs real scoring value and can leave an awkward continuing position. A miss toward 5 produces 110 remaining; toward 1, 114. Neither is a catastrophe, but neither gives the same clean route that landing treble 20 provides. The geometry here is working against you on both sides, which is precisely why the switch to treble 19 becomes the correct structural call when grouping drifts consistently below the bed. The 19 is flanked by 3 on one side and 7 on the other — both score more than 1 or 5, and both more often preserve a clean three-dart route into a finish. The switch is not a concession when drift is present. It is the geometrically stronger decision. On the question of how the route runs, the route from 115 runs three darts because no scoring dart from here leaves a direct two-dart finish available. T20 creates the initial scoring position, 15 moves into the exact finish window, and D20 ends the leg. Each dart has a specific job in the sequence, and the route collapses when any one of them is thrown to the eventual close rather than to its immediate role. Particularly on 15 — the bridging dart — there is a tendency in match conditions to rush toward the double before the position has been properly set. That tendency produces worse averages on three-dart finishes than on two-dart ones, despite the extra dart. The fix is committing fully to 15 before thinking about D20. As for when to use the alternate, both routes close the leg from 115 through comparable finishing doubles — the primary on D20 and the alternate (T19 → 18 → D20) on D20. The difference is the approach: T20 versus T19 on the opening dart, and different bridging sequences to reach the close. Switch to the alternate when the primary's approach is not finding the right grouping, and treat it as an equally valid line rather than a compromise.
When and Why to Use This Route
Use this route as the standard approach from this score. Scoring hard through T20 and finishing on D20 is the combination that wins the most legs — not just in comfortable situations, but especially in tight ones where both components need to deliver simultaneously.
This is an aggressive route that does not sacrifice reliability. T20 scores hard and applies pressure. D20 closes cleanly and forgives slight misses on the final dart. The combination is what makes this route correct as the default from this score — it does not require ideal conditions to work, and it does not need the player to choose between being aggressive and being controlled.
Why Players Miss This Finish
The most common pattern in a missed 115 checkout: T20 lands cleanly, 15 is rushed or slightly off, D20 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 15 — giving it the same deliberate attention as the opening dart — close 115 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 115, 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 → 15 → D20 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 115 practice session. When T20 drifts into 5, the leave is 110 — 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 114 — 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.
