You know the move was bad. Not why.
You see the evaluation drop, but the underlying tactical or positional idea isn't obvious.
Chess improvement that connects the dots
Don't just see the best move. Understand your chess.
Build your opening repertoire, play against Stockfish with coaching feedback, and review your games move by move with explanations you can actually use.
- Opening preparation
- Play vs Stockfish
- Game analysis
- Coach explanations
CoachPlaying Stockfish · White to move
+1.4Position idea
Black has weakened the dark squares around the king. Your bishop and queen are already pointing toward h7.
Consider: Bxh7+You played: Re1
Re1 is playable, but it misses the tactical opportunity. Ask yourself: what changed after ...h6?
Stockfish tells you what. MyChessTree helps explain why.
THE GAP BETWEEN SEEING AND LEARNING
Chess engines are incredibly strong. Understanding them is harder.
An evaluation bar can tell you that your position went from +0.3 to -2.1. It doesn't automatically mean you understand the mistake.
Opening study becomes endless.
Databases contain huge numbers of variations, while only a fraction matter in your actual games.
Analysis gets forgotten.
Reviewing one game doesn't help much if the lesson never makes it into how you prepare and play the next one.
MyChessTree connects preparation, practice, play and review.

COACH · YOUR LAST MOVE: 17. QE2
Good idea, but there is something more forcing here.
Black's knight on f6 is overloaded: it protects both h7 and d5. Try looking for a forcing move against the king.

PLAY & COACH
Play Stockfish with a coach beside you.
Testing yourself against a strong engine is more useful when you can understand the decisions behind the position. MyChessTree combines engine play with coaching feedback so the game itself becomes a training session.
- Play full positions against Stockfish
- Receive coaching feedback while you play
- Inspect candidate moves and plans
- Keep learning without leaving the board
GAME ANALYSIS
Your game ended. The learning shouldn't.
Analyze a completed game with Stockfish, identify the moments that changed the evaluation, then ask the coach about the moves you don't understand.
- Review evaluation changes and critical moments
- Select move context from the board, graph or move list
- Ask follow-up questions about the position

ANALYSIS CHAT
Analysis should end with an idea, not an evaluation number.
Use the engine to find what changed. Use the coach to understand why.

Build my opening tree OPENINGS + COACH
Ask what the opening is trying to accomplish.
Opening preparation shouldn't be only memorizing notation. Ask for an explanation of the position and the ideas behind your moves.
Opening Explanation
The Caro-Kann gives Black a solid pawn structure while preparing ...d5 without blocking the c8 bishop.
PRACTICE
Turn preparation into moves you can actually play.
Once you've built a tree, practice the repertoire on the board instead of just reading it.

Your chess shouldn't live in five different tools.
MyChessTree keeps the important parts of improvement connected: what you prepare, what you play, what went wrong and what you should understand next.

ENGINE + COACH
Engine strength. Coaching context.
Stockfish gives you
- Evaluation
- Best moves
- Candidate lines
- Tactical truth
The coach helps you ask
- Why is this move better?
- What changed in the position?
- What should I have noticed?
- What plan am I missing?
Use both.
INTERACTIVE EXAMPLE
Ask the questions you actually have after a game.
Selected move: 18...Rc8?!
ASK THE COACH
The main problem with 18...Rc8 isn't that the rook is badly placed. It gives White time for e5, attacking the knight and opening the diagonal toward your king.
