Analytical Depth

75+ Analytical Signals

Validated on 10,000+ games — 4,000+ verified SuperGM games and 6,000+ confirmed engine games. Each signal targets a distinct fingerprint that separates human cognition from engine assistance.

Pressure Response
How accuracy changes in critical, high-stakes positions. Humans react differently to pressure than engines.
Behavioral
Error Distribution
The shape and texture of errors across the game. Human error patterns are fundamentally different from algorithmic ones.
Statistical
Recovery Dynamics
What happens after a mistake. The speed and pattern of recovery reveals whether a human or machine is playing.
Behavioral
Complexity Awareness
Whether accuracy correlates with position difficulty. Engines don't care how hard the position is. Humans do.
Statistical
Move Selection Profile
The distribution of move quality across the full game. Patterns invisible to the naked eye but clear to forensic analysis.
Statistical
Baseline Comparison
Every metric compared against our authenticated database of verified SuperGM performances and confirmed engine games.
Statistical
Phase Analysis
Opening, middlegame, and endgame evaluated independently. Each phase tells a different story about the player's cognition.
Behavioral
Strategic Tension
How board complexity is managed over time. Humans simplify to reduce cognitive load. Engines sustain maximum tension.
Behavioral
Risk Tolerance
Decision patterns in winning positions. Humans seek safety. Engines maximize regardless of volatility.
Behavioral
Brilliance Detection
A secondary system that identifies genuine human flow states — protecting elite players from false accusations.
ML-Enhanced
Tail Distribution
Mathematical analysis of the error distribution's shape. Human errors follow distinct statistical laws that engines cannot replicate.
Statistical
ML Verification
An independent machine learning model — trained on 10,000+ games — verifies the behavioral findings. Under 1% false positive rate on SuperGM play.

The Problem

Why This Exists

A 14-year-old wins a scholastic tournament. The losing parent demands an investigation. The tournament director has nothing — no tools, no data, no evidence. They either ban an innocent kid on gut feeling or let a real cheater walk with the trophy. Both outcomes destroy trust.
Chess.com closes tens of thousands of accounts per month. They overturn a fraction of appeals. They never show you the evidence. You get a form email that says "Our system has determined..." and that's it. Your rating, your history, your reputation — gone. No recourse.
ChessForensics exists because competitive chess deserves due process. Not black-box algorithms. Not gut feelings. Not angry parents screaming at arbiters. Objective, mathematical, evidence-grade forensic evidence — delivered as a report you can hand to anyone and say: "Here's the proof."
FAQ

Common Questions

How accurate is ChessForensics? ▶
Validated on 10,000+ games — 4,084 verified SuperGM games and 5,936 confirmed engine games. Cross-validated false positive rate: under 1% on SuperGM play. Zero false positives on named SuperGM accounts (Magnus Carlsen, Alireza Firouzja, Nihal Sarin, David Navara, Etienne Bacrot). Engine detection rate: 99%+ on depth-20 engine play. Every report includes a confidence score and full signal breakdown.
Will this work for my Elo range? ▶
ChessForensics is calibrated against SuperGM blitz play (2700+ Elo). For players below 2000, the behavioral signals are less precise because lower-rated games have higher natural variance. The report will clearly state when confidence is reduced due to game characteristics.
Can I use this to appeal a Chess.com or Lichess ban? ▶
Yes. Export your game as a PGN (both platforms allow this even after a ban), upload it, and attach the ChessForensics report to your appeal. It provides independent, third-party evidence that your play matches human behavioral patterns. Whether the platform accepts it is their decision, but you'll have the data on your side.
What if the result is inconclusive? ▶
You pay nothing. If ChessForensics returns an INCONCLUSIVE verdict due to insufficient game data (too few moves, missing critical positions), we refund your purchase in full. No questions asked.
Do I need clock data in my PGN? ▶
Strongly recommended but not required. PGNs with clock annotations (like Lichess exports with %clk tags) unlock additional timing-based behavioral dimensions. Without clock data, the analysis relies purely on move quality signals — still effective, but fewer dimensions are available.
How long does the analysis take? ▶
Typically 2–5 minutes per game depending on game length. Our engine evaluates every position at depth 20+ with multi-PV analysis, then runs the full 35-dimension behavioral pipeline. You'll see a real-time status update while it processes.
Is ChessForensics affiliated with Chess.com, Lichess, or FIDE? ▶
No. ChessForensics is a fully independent forensic analysis tool. We are not affiliated with any chess platform or governing body. Our reports are independent third-party assessments — that independence is what makes them valuable as evidence.
What's included in the Event Retainer? ▶
Unlimited game analyses for 7 days, white-label forensic reports with your tournament branding, bulk PGN upload (entire tournament at once), a dedicated support channel, and arbiter summary dashboard showing flagged games at a glance. Contact us for custom API integration with your pairing software.
