What Kingsights analyzes in your games

Most players analyze games one by one, missing the patterns that actually hold them back. Kingsights looks at your entire history to find structural leaks.

Opening Win Rates

See exactly which openings score you points and which ones are draining your rating.

Move-by-Move Mistakes

Identify the specific moves where you consistently blunder across multiple games.

Resource Management

Analyze how you use your time and pawns compared to your opponents.

Style Profiling

Discover if you're a tactical sharp-shooter or a positional grinder based on your results.

Hero & Villain Systems

We pinpoint your absolute best 'Hero' opening that you should play more, and your 'Villain' opening that needs immediate study or replacement.

Why this beats single-game engine analysis

Stockfish is great for telling you that you blundered a knight on move 14. But it won't tell you that you've blundered that same knight in the same variation 5 times this month.

Am I losing because of tactics or position?
Do I play too fast in winning positions?
Is my repertoire too broad or too narrow?

Aggregated Data

One game is luck. 500 games is a statistic. We give you the statistical truth about your play.

Pattern Recognition

Humans learn by spotting patterns. We automate that process for your chess games.

Objective Reality

Stop guessing which opening 'feels' good. Start playing the one that actually wins.
