Preflop Exploit Lab: Own Every Seat at the Table

📌 TL;DR

Preflop Exploit Lab is a complete preflop intelligence suite built on top of Maxploit's debiased hand database.

Three tools, one mission:

• 🎯 Matchup Matrix — every position-vs-position node as a live grid
• 🔍 Leak Scanner — your pool diffed against equilibrium, cell by cell
• 🗺️ RangeChart — a 13×13 combo grid with debiased frequencies, equity, and confidence

From BTN opens to 4-bet pots in the blinds, there is no node you cannot dissect.

Preflop is the street everyone "knows" — and the street nobody actually solves.

That's exactly why it's the most exploitable.

🩸 The Problem: Preflop Is Where Money Leaks Silently

Every single hand starts preflop. Every cold-call, every squeeze, every 3-bet range — it all compounds.

And yet, most players attack preflop with the worst possible toolkit:

• Memorised solver charts that were trained against an opponent your pool isn't
• Raw observed frequencies that swing 15–20% based on 200-hand samples
• Blind spots on how positions actually interact: what does BB really do vs CO opens at 50NL?

Solver charts tell you what a perfectly balanced opponent does.

But your opponents aren't perfectly balanced — and the gap between the two is where your edge lives.

The problem has never been that the edge isn't there. It's that nobody has built the tool to see it.

Preflop Exploit Lab exists because every poker map you've been reading has been missing the most important layer: what the pool is actually doing.

⚙️ Three Tools, One Lab

🎯 Matchup Matrix — Every Position Pair, Every Action

Forget single-position statistics. The Matchup Matrix shows you every position-vs-position interaction as a live frequency grid — BTN vs BB, CO vs SB, UTG vs BTN, all of them.

Matchup Matrix: BB vs CO Open, filter your targeted matchup in seconds.

For each pairing you see:

• Open-raise frequency
• 3-bet, Cold-call and Fold-vs-open
• Fold-to-3-bet and 4-bet (allin split vs non-allin)
• Strength (average raw equity) of each action branch

Flip on Compare Mode and stack two databases side by side:

• Your pool vs GTO
• Your pool vs a higher-stakes pool
• Your own hero data vs the rest of the table

The entire matrix diffs in real time.

This is how you answer questions like:

"Does BB actually defend wider vs HJ than vs CO in my pool?" (Spoiler: usually no, but the gap varies by stake.)

"Does my pool fold to 3-bets more when they opened from CO or from BTN?"

You stop guessing. You start measuring.

🔍 Leak Scanner — Your Pool, Diffed Against Equilibrium

The Leak Scanner is the kill switch on preflop exploitation.

See how much are the NL50 pool BB overfolding against a open raise from CO.

Load your database, pick a reference (GTO, or any other DB), flip the RangeChart to Leak mode, and the entire 13×13 grid recolours as a two-tone delta heatmap:

• 🟠 Orange cells — your pool does the action more often than the GTO
• 🔵 Blue cells — your pool does the action less often than the GTO

That's it. Orange and blue do not mean "aggressive" or "passive". They mean higher or lower than the reference data, relative to whichever action you're focused on.

• Focus on Raise: orange cells = combos the pool raises too often, blue = not enough
• Focus on Fold: orange cells = combos the pool over-folds, blue = combos the pool never folds when GTO would
• Focus on Call: same logic, against the Call frequency

Click any action block above the grid to swap the lens — the entire heatmap recolours instantly.

Built-in noise handling:

• Combos with low observation counts fade out automatically so you don't chase small-sample ghosts
• Quality flags mark low-sample nodes and off-range hands
• A threshold slider lets you hide deltas smaller than your confidence band

In 30 seconds you have the entire preflop leak inventory for a 40k-hand population. That's a product nobody else is shipping.

🗺️ RangeChart — The 13×13 Truth Serum

The RangeChart is the beating heart of the Lab.

Side-by-side comparison, imbalanced 3betting range from BB revealed instantly.

Every combo, every action, every equity bucket — rendered as a 13×13 grid with colour-coded action bars stacked inside each cell:

• Hover any combo → tooltip with frequency, observation count, and confidence band
• Click an equity bucket → filter the grid to, say, "just the strong hands in the calling range" or "just the air in the 3-bet range"
• Focus any action → sidebar and grid both re-weight to that action in isolation

And here's the trick: the numbers you see aren't raw observed showdown counts.

They are the output of Maxploit's debiasing engine:

• Small-sample noise corrected toward a GTO prior, weighted by how much data you actually have
• Parent-node selection bias undone
• Low-observation combos blended automatically

You see the range your pool is actually playing — not the distorted shadow that your raw HH sample happened to record.

🔬 Under the Hood — Why Debiased ≠ Raw

You probably noticed the word debiased more than once. Here's the short version.

Raw preflop frequencies on small samples are noisy and biased:

• A few hands swing AA "RFI frequency" from 87% to 100%
• Parent-node filtering inflates child-node samples (3-bet spots inherit the opener's selection)
• Combos outside a rational opening range show up for bad reasons (odd clicks, recreational limps)

Maxploit's engine runs equity-seeded Bayesian debiasing with cross-node parent weighting on every preflop decision point:

• Low-observation nodes blend toward the GTO prior
• Top-of-range hands are protected against over-correction
• Out-of-range combos are folded by construction

You don't have to think about any of this when you use the Lab — just know the numbers are built to hold up under small samples.

🚀 Get Into the Lab

1. Log in at Maxploit and open the Preflop tab
2. Pick your database and table size (currently 6-max only)
3. Jump between Matchup Matrix, RangeChart (Range view), and RangeChart (Leak view)
4. Turn on Compare Mode to stack databases side by side
5. Enable Hero Mode to isolate your own play from the pool

The map of your pool is already there. The Lab just makes it visible.

Stop memorising charts. Start reading your pool.

Every seat at the table has a leak. Preflop Exploit Lab finds all of them before the flop is dealt.
