Do you solve chess puzzles by pattern and then fail to explain why the move actually wins? Have you ever seen Nxe4 win a rook and had no idea what tactic just happened? The AI Chess Puzzle Explainer takes a specific position, a specific move, or a full puzzle and walks you through the threat, the calculation, and the tactic in words a club player can act on.
Short answer: The AI Chess Puzzle Explainer teaches a specific tactic in a specific position, naming the threat, laying out the forced sequence, and identifying the pin, fork, skewer, or discovery that wins.
What is AI Chess Puzzle Explainer?
The AI Chess Puzzle Explainer is a free browser tool that turns a chess puzzle into a plain English lesson. You paste the position, the moves you tried, and the solution you saw on a puzzle site, and the tool returns a walk through that names the tactic, calculates the forced sequence, and explains why the losing side had no defence.
It uses standard algebraic notation such as Nxe4, Qh5+, and Rxf7. Evaluations sit inside a code block when they matter, so you can see whether a line is winning or only slightly better. The AI Chess Puzzle Explainer is a study aid, not an engine, and it says so plainly when a line is unclear.
Why Use AI Chess Puzzle Explainer?
Solving a puzzle without understanding it is a slow way to improve. You remember the shape for a week, then miss the same idea in a game. The AI Chess Puzzle Explainer closes that gap by describing the tactic in words your brain can reuse across positions, not just the one you solved.
It also helps when a puzzle solution feels wrong. Sometimes the given first move looks weaker than a sacrifice you saw. Ask the tool why the given move wins and it will explain the defensive resource that ruins your alternative. That kind of counter analysis is where pattern learning becomes real understanding.
Study note The AI Chess Puzzle Explainer is a training partner, not an engine. Use it to translate solutions into ideas, and use a real engine when you need a verified evaluation.
Who Uses the Puzzle Explainer?
The AI Chess Puzzle Explainer suits club players, students, coaches, and streamers who want to say more about a puzzle than the answer is Nxe4. That includes rating grinders on puzzle sites, teachers preparing a lesson for a school team, chess streamers annotating a daily puzzle, and adult improvers working through a tactics book.
- Club players in the 1200 to 1900 range building tactical vocabulary.
- Coaches writing training plans that need clear explanations for students.
- Streamers annotating a daily puzzle for chat before a session.
- Adult improvers reading through classic tactics books at their own pace.
- Junior players preparing for weekend rated events.

Session History
Every puzzle you asked about in the current session stays in the activity panel for quick review.
How Does AI Chess Puzzle Explainer Work?
The AI Chess Puzzle Explainer opens on a single working screen. A large prompt box sits at the top for the position in FEN or PGN, the moves you tried, and the specific question you want answered. Under the prompt, an AI model selector lets you route the puzzle through MSB AI, OpenAI ChatGPT, Anthropic Claude AI, Google Gemini, DeepSeek, or OpenRouter AI when you want a second opinion.
Beneath the model row, an advanced options accordion reveals Depth, Angle, Output Format, Audience Level, four analytical toggles, an Analytical Rigor slider, and a custom instructions field for notation preferences. Click Generate and the explanation streams into an output card with a live word count so you can watch the walk through complete.
Each finished explanation carries its own action row. Copy sends the annotated puzzle to your clipboard, Listen reads the lines aloud for spaced repetition, Reuse pushes the answer back into the prompt for a follow up such as what if Black plays Ra8 instead, and Download exports DOC, TXT, or HTML. The activity history panel keeps every puzzle from the current session so a follow up can reference the previous line.
Training tip Ask the AI Chess Puzzle Explainer to name the tactic before it shows the moves. Guessing the tactic first is how the pattern actually sticks.

Step by Step Guide
- Open the AI Chess Puzzle Explainer and paste the position in FEN or PGN. Add the side to move and the solution you saw on the puzzle site.
- Type your specific question in one line. What is the tactic works better than please explain.
- Pick an AI model. Anthropic Claude AI reads calmly for lessons, DeepSeek is a strong second opinion on tactics.
- Open the advanced options accordion. Set Depth, Audience Level, and Output Format for the study moment.
- Turn on Include Data Points and Include Risks and Caveats for tactical puzzles. Turn on Next Steps for a lesson plan.
- Nudge Analytical Rigor near 75 for daily study. Push to 90 for complex sacrifices.
- Click Generate and read the walk through with the board in front of you. Use Reuse to ask what if the defender plays a different move.
Run this checklist before you close the tab on a puzzle.
- ✅ You can name the tactic in one word before you re read the explanation.
- ✅ Every candidate defence is either answered or clearly refuted.
- ✅ The winning sequence is written in algebraic notation, such as Nxe4 or Qh5+.
- ✅ You have walked the line on a real board or in your head, not just skimmed the text.
- ✅ The explanation is saved to a notebook if you plan to revisit the pattern.
Example Position and Walk Through
Here is a short input pattern and the kind of walk through the AI Chess Puzzle Explainer returns. Notation is standard algebraic and evaluations sit inside code where they matter.
Input White to move. Solution given as Nxe4. Black king on g8, rook on f8, queen on d7. My move was Bxf7+. Please name the tactic and show why Nxe4 wins.
Walk through The tactic is a double attack after Nxe4. The knight forks the queen on d7 and threatens the rook on f8 via a discovered attack. Your Bxf7+ line loses to Kxf7 with an evaluation near 0.0, because White has no follow up. After Nxe4, if Black plays Qxe4, White wins the exchange with a clean position, evaluation near +2.5.
Common Tactics It Recognises
- Forks, from simple knight forks to royal forks winning the queen.
- Pins, both absolute pins against the king and relative pins against material.
- Skewers on long diagonals and open files.
- Discovered attacks and discovered checks, including double check.
- Deflections, decoys, and clearance sacrifices.
- Zwischenzug lines that break a forcing sequence.
Honest Pros and Cons
Strengths
- Names the tactic in plain English and shows the forced sequence.
- Depth and Audience Level adapt the lesson from junior to expert.
- Rigor slider forces the model to sit closer to concrete lines.
- Free to use with no login and no export cap.
Limits
- The AI Chess Puzzle Explainer is not an engine. Use one for verified evaluations in serious analysis.
- Very deep positions can trip a language model, so set Rigor high and check the line by hand.
- The tool cannot read a photo of a board. Give it FEN or PGN.
Tips and Common Mistakes
The most common mistake is asking the AI Chess Puzzle Explainer to solve a puzzle rather than to explain a known solution. It shines when you paste the solution and ask why it works. Solving is what an engine is for.
Do not do this Do not trust an explanation without setting up the board and playing the line. A wrong line in a study notebook is worse than no line at all.
Other traps include leaving Audience Level on Expert with a beginner student, forgetting to state which side is to move, and pushing Depth to Comprehensive on a two move puzzle. Match the setup to the position.

Frequently Asked Questions
Do I need an account to use the AI Chess Puzzle Explainer?
No. Open the tool, paste your position, and click Generate. Nothing is stored against a login and nothing is metered.
