101 Checkout in Darts — T17, 10, D20
The 101 checkout uses a three-dart route through T17, 10 into D20. At this score, controlling the first dart is the central challenge — everything else in the route depends on where T17 lands. A clean execution through T17 → 10 → D20 leads directly into D20, one of the strongest finishing doubles on the board and a consistent closer under match pressure.
The miss geometry on the opening dart favours the 2 side. A drift from T17 in that direction leaves 99 — T19 → 10 → D16, which preserves a working route. The 3 side produces 98, a harder position to continue from. That asymmetry is useful information: the pre-throw setup can subtly bias the release toward the 2 side without altering the fundamental mechanics of the throw. Knowing which direction is the preferred miss before stepping to the oche removes a decision that would otherwise be made reactively — and reactive decisions under pressure rarely favour the better outcome.
The decision about which route to use from 101 should be made before stepping to the oche — not at it, and not during the visit. Arriving at the line already having chosen T17 → 10 → D20 removes an entire category of thought from the throw. Players who are still weighing options as they step forward introduce a kind of cognitive load that does not appear in practice but is consistently present in match conditions. Deciding the route in advance and committing to it completely is the structural version of pressure management — it reduces the number of decisions that need to be made while throwing.
Finishing 101 reliably in match play is a trainable skill. Players who build it deliberately — through structured pressure practice rather than hoping for composure — outperform those who rely on natural calm. Control on the first dart at 101 is more valuable than any other single factor. The rest of the visit stays structured when the opening dart lands clean. Pressure reveals the quality of the routine. Players with a consistent pre-throw process handle 101 in competition almost exactly as they do in practice. The throw fails under pressure when timing changes — not when aim changes. That distinction matters because it points directly to the fix. The routine before the throw matters as much as the throw itself. A consistent pre-throw process delivers a consistent throw regardless of what is riding on it.
If the opponent is on a finish, this is the route to back — aggressive through T17 and closing on D20, one of the best doubles on the board.
Route Comparison & Target Selection
Primary: T17 → 10 → D20
treble 17 (51), single 10, closing on double 20 — high-percentage close
Alternate: T17 → DBull
treble 17 (51), closing on bull (50) — direct bull finish
These routes differ on close type as much as approach. The primary finishes on D20, a standard double that splits cleanly and provides a known recovery. The alternate finishes on the bull, which is more direct but leaves a harder position on a miss. For most match situations, D20 through the primary is the correct call. When the opponent is close and the fastest finish takes priority, the alternate's bull close is the right adjustment.
On 101, 3 is the anti-target. Drifting into it leaves 98 rather than the more manageable 99 from 2.
Miss Geometry, Route Structure & When to Use the Alternate
Treble 17 sits between 2 and 3. A miss from 101 into 2 leaves 99; into 3 it leaves 98. Of those two outcomes, the 2 side is preferable — 99 remaining gives a cleaner route forward than the 98 produced by drifting the other way. The throw setup should reflect that preference: releasing with a slight lean toward 2 without overcomplicating the mechanics. Understanding and using the preferred miss direction on every opening dart is the kind of marginal gain that accumulates over a match into a genuine positional edge. Considering the route structure, 101 cannot be closed in two darts, so the route extends to three: T17 → 10 → D20. T17 scores the opening position, 10 reaches the exact number needed for the close, and D20 finishes the leg. The route holds together when each dart is thrown to its role in sequence rather than with one eye on the eventual double. The second dart (10) is where most execution errors on three-dart routes occur — it is the dart most affected by anticipation of the close, and it is the dart that determines whether D20 is reached from a position of control or a position of recovery. Where the alternate comes in, finishing on D20 gives the primary a closing advantage over the alternate's DBull. In match play, arriving at a stronger double through the same general route structure is a real edge — the primary provides it. The alternate (T17 → DBull) is the route adjustment when the primary's approach is not landing as expected, but when both are available, the primary's better close makes it the correct default.
When and Why to Use This Route
This route is correct whenever this score appears. The decision has already been made — T17 into D20 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. T17 handles the first problem. D20 handles the second. Neither dart is a weak link.
Why Players Miss This Finish
Players miss 101 because they bring a two-dart mindset to a three-dart route. When T17 lands well, the impulse is to jump mentally to the close — to start aiming at D20 before 10 has landed. That forward projection reduces the quality of 10 in exactly the same way that thinking about the result of any throw reduces the quality of that throw. The fix is discipline on the middle dart: throw 10 as its own complete decision, with the same focus given to T17, and only then address D20.
Improving on 101 in competition comes from accepting that the throw will not always be perfect and building an automatic response to imperfection. The players who drop this score are usually players who need everything to go right. The players who close it are the ones who have practised enough variants of the route — clean first dart, slightly off first dart, both miss directions — that the visit runs on autopilot regardless of the opening outcome.
Practice
Build the 101 checkout through the middle dart. T17 and D20 receive most of the practice attention in most players' routines — T17 because it opens the visit and D20 because it closes it. But on 101, 10 is usually where the leg is won or lost. A clean T17 that is followed by a slightly rushed 10 leaves D20 from a weaker position than the route intended. Give 10 deliberate practice in isolation — it is the least-practised dart in most three-dart routes and the one that determines whether the close is routine or difficult.
Add consequence to the end of every 101 practice block. After completing the route a set number of times cleanly, throw T17 deliberately off-line and practise continuing from 98 and 99 without resetting. This forces the continuation habit — the automatic response to a miss on the opener that keeps the visit running rather than stalling. Players who have practised their recovery positions finish more legs from imperfect visits than those who only ever practise the clean route.
