1. Why your Spin & Go winrate is decided in the Blinds (SB and BB)
In 3-max (and even more so heads-up), you post a mandatory blind two hands out of three. Among all losing or break-even Spin & Go players, database analysis shows that their winrate on the Button is almost the same as good regulars', but that they lose between 12 and 25 chips of EV per game in the Small Blind and Big Blind.
Without an automated diagnostic tool these losses are invisible to the naked eye: folding one blind too many every 8 hands causes no emotional pain in the moment, yet it completely destroys your ROI by the end of the month.

2. The 7 most expensive EV leaks detected by the "My Leaks" module
In SpinCrusher, the ☠ My Leaks (Hero Leaks Diagnostic) tab automatically audits your frequencies and compares them to optimal ranges. Here are the 7 most common leaks and their fixes:
| N° | Detected Leak (Hero Leak) | Statistical Symptom | Estimated Loss | Immediate Fix |
|---|---|---|---|---|
| 1 | BB overfold vs BTN min-raise | BB fold vs BTN > 58% (at 16–25 BB) | -4.5 cEV / g | Defend all your suited combos and connectors and add 3-bet shoves with Ax/PP. |
| 2 | Missing 3-bet shove in SB vs BTN | SB 3-bet shove < 11% (at 12–18 BB) | -3.8 cEV / g | Re-shove your aces, pairs 22–88 and Broadways aggressively against wide BTN opens. |
| 3 | Excessive flop folding (Fold to C-Bet) | Fold to flop c-bet OOP > 56% | -3.2 cEV / g | Add check-raises (12–15%) as semi-bluffs and float with backdoors + overcards vs 1/3 pot. |
| 4 | Forgetting the BB turn probe bet | Turn probe < 38% after a flop check-back | -2.9 cEV / g | When the aggressor checks back the flop, their range is capped: attack the turn at 50–66% of the pot. |
| 5 | Auto c-bet 100% without checking the profile | Flop c-bet > 82% against Calling Stations | -2.6 cEV / g | Check the [CCB] badge: check your pure air against players who call > 60% on the flop. |
| 6 | Passivity in BvB (SB vs BB) | SB fold in BvB > 22% or Limp-Fold > 60% | -3.1 cEV / g | In a battle of the blinds, play 85%+ of your hands, mixing limp and raise/shove. |
| 7 | Hero-calling the river against passive profiles | River call vs 3rd barrel from a [PAS] player |
-3.5 cEV / g | The pool massively under-bluffs the river on 3-barrels: fold your bluff-catchers against passives. |
3. Using the SpinCrusher Matrix PRO database (cross-spot stats & 200+ flop textures)
Beyond your own leaks, SpinCrusher's ⌖ Leakfinder (Field & Pool Analysis) tab includes the SpinCrusher Matrix PRO analytical framework. You can cross more per-depth and per-spot stats by:
- Pot type: Limp Pot, Single Raised Pot (SRP), Iso-Raise Pot, 3-Bet Pot.
- More than 200 flop textures: dry Ace-high boards (
A72r), low connected boards (875ss), paired boards (KK4), monotone boards (Q94sss). - Max EV Sizing Comparator: find out in one click whether a 1 BB, 33%-pot or 75%-pot c-bet generates the most EV against the pool on a given texture.
4. A 5,000-hand audit protocol with Leakfinder & Replayer
