The Method

A closed loop of deliberate
improvement.

01

Train

High-intensity pattern recognition training. The Woodpecker method forces you to see patterns, not calculate them.

Woodpecker high-rep mode
Pattern exposure engine
Adaptive puzzle sequences
02

Track

Every attempt is measured. Recognition speed, error type, and stamina are recorded across each session.

First-move recognition time
Mistake classification
Session fatigue curve
03

Improve

Your coaches see exactly where you break down. Drills are focused on your specific cognitive gaps, not general practice.

Automated weakness detection
Targeted drill recommendations
Coach diagnostic insights
Analytics Engine

I've never seen chess analytics

like this before.

"Recognition speed is stabilising on Forks. Shift focus to Discovered Attacks and Back Rank patterns. Keep sessions under 20 minutes to avoid fatigue-induced errors."

Coach Mode

Your coach sees
how you think.

This isn't about tracking wins and losses. RankNFile gives coaches a live window into how each student processes positions — where they hesitate, where they rush, and where their pattern recognition breaks down under fatigue.

Cognition Diagnosis
Not just "track progress" — understand the specific cognitive gap holding each student back.
