Detect and replay your preflop mistakes

On every import, the preflop mistake detector sorts everything automatically: out of all the hands you play, it isolates the ones where you deviated from your reference preflop chart (we'll come back to the notion of reference chart further down), for each position.

The preflop mistake detector shows up in three places in Poker Spin Tracker. The first two were already covered in the chapters Hands view or Spin view? and The Filter panel, so we won't go over them again in detail.

1. In the Mistakes only Quick Filter

The Mistakes only Quick Filter activates a mode where only hands flagged as mistakes appear in the table. It's the fastest shortcut to gather the hands worth reviewing.

2. In the filter panel

The exact same filter is also available in the filter panel, just click on EV & Accuracy.

3. In the import summary

After every import, an Accuracy by situation panel aggregates the diagnosis: for each preflop situation (M3 BU, HU SB, M3 BB vs SB limp, etc.), the tracker shows the overall accuracy, accuracy vs Reg, accuracy vs Fish, and the dominant mistake by category (Fold / Call / Raise / All-in). Clicking a row opens the details of the combos involved.

Don't worry, all the details come further down in this chapter.

The goal is simple: come back regularly to your preflop mistakes to spot recurring deviations, then fix the automatic habits that are costing you chips.

The right reflex is therefore to step back from each flagged mistake and clearly distinguish what is a real mistake from what is a conscious exploit.

The rule is simple and binary:

Two practical consequences:

• An action played at 0.5% frequency for that hand: not a mistake. Rare, but present.
• An action never allowed for that hand: mistake, even if it seems reasonable in the situation. Note that any frequency below 0.05% is treated as zero.

Take an example: in HU SB 7-8 bb vs Reg, suppose your chart only allows Call with J3s.

There is no intermediate warning threshold, no gradation. Either the action is allowed for this hand in the chart, or it isn't. This simplicity makes the detector sharp, but also entirely dependent on the reference chart used.

By default, the tracker uses:

• The GTO charts against regs
• The Exploit charts against fish

These default charts come from Poker Sciences and remain available in your Chart Library.

Each combination of situation and stack bucket (blind level, e.g. 6-8 bb) has its own reference chart.

With the Preflop Pack, as soon as you create custom charts (covered in Module 6), they automatically replace the default reference for the situations involved. The detector then aligns with your strategy.

It's a self-coaching tool: you tell it what you want to play, and it tells you when you stray from it.

If you don't have the Preflop Pack, the tracker still automatically uses the Preflop Pack default charts to compute your preflop accuracy. You just can't customize them.

The import summary modal opens automatically at the end of an import. If you'd rather skip it, an account preference lets you disable it once and for all (and re-enable it later if you change your mind).

Its structure, from top to bottom:

• Four KPIs in tiles: Tournaments played, Time played, Total profit, CEV
• Field Quality: a global donut showing the fish/reg ratio you faced during the import. Clicking the panel opens the breakdown by buy-in (we will look at this in more detail in Module 8)
• Preflop Accuracy: the panel that gathers the diagnosis of your mistakes (next section)

The import summary gives you direct access to the preflop mistake rates of the hands you just imported.

The table by situation (on click)

Clicking the donut switches to a detailed table where each row is a situation encountered during the import.

Clicking a row opens a mini 13×13 grid of combos: the cells are colored in red (intensity proportional to the number of mistakes). At a glance, you can tell whether the mistake is concentrated on a few specific combos (a targeted leak to fix) or scattered across the whole range (more of a general lack of familiarity with the spot).

Listing your mistakes is good. Fixing them is better. The Replay mistakes button at the bottom right of the import summary, beneath the Preflop Accuracy panel, opens a dedicated mode that works like the Trainer and has you replay your mistakes.

One question, one answer

You're put in a spot just like in the regular Trainer: your hand, the opponent (reg or fish) with their stack, your stack, and a counter of remaining mistakes at the top. It's up to you to pick the action you should have played from the buttons offered.

Smart behavior

If you deviated five times with A5o in the same spot during the import, you won't get five questions.

Questions are then presented in random order and capped at the count you requested. By the end, you've replayed the bulk of your mistakes in just a few minutes, with immediate feedback on each one.

Alright... this last chapter of module 5 was a bit dense, but hopefully it's still understandable. If some points aren't fully clear yet, feel free to read it again at your own pace, then if needed come over to Discord to ask any questions you may have.

To sum up, there are 3 different ways to review your mistakes in Poker Spin Tracker:

And so ends the last chapter of module 5.
