Chess By Principle finds the recurring patterns in your games—the decisions that keep costing you points—and trains you to make better ones. No engine scores. No centipawns. Coaching language that builds the thinking process strong players use.
5 games/month free. No credit card required.
The engine tells you Nd5 was better. It doesn't tell you why you didn't see it—or what you were thinking when you played something else. Knowledge of the right move isn't the same as the process that finds it.
You now know what went wrong. You don't know why you thought what you did was right—so next week, you do it again.
You now know what step you skipped, and why it cost you. That's what sticks.
Strong players don't calculate randomly. Before every move, they run the same process—every time, without exception.
After every game you analyze, we show you which step you skipped—and on which move.
Every lesson in your report is tied to a specific move, a specific principle, and what to do differently next time.
There is no fixed priority order. King safety, material, piece activity, pawn structure—these four always apply, but the position determines which one to evaluate first. We read the position type before we apply the framework.
After every game, your coaching profile updates. Recurring weaknesses get tracked by name—not just flagged once and forgotten. The third time your rook stays on its starting square past move 15, we call it out directly.
Over time, your profile builds a picture of how you actually play—your preferred openings, your strongest and weakest skill areas, where your thinking process breaks down. A coach that remembers every game you've ever played.
Most chess improvement programs focus on what you should have played. CBP is built around a different question: why did you think your move was right? That distinction is the entire gap between knowledge and skill.
