Studying a chess game shouldn't mean constantly rewinding a video, dragging pieces around on a board, or trying to remember where the pieces were three moves ago.
That's why we've built Sequence Trainer for Chess Move Chooser — a simple, focused way to replay and analyse chess move sequences directly in your browser.
♟️ Turn Any Chess Line Into an Interactive Study
Whether you're reviewing your latest game, studying an opening variation, working through a tactical line, or following a classic game, Sequence Trainer lets you load the moves and walk through them one position at a time.
Enter a starting position using FEN, paste in a sequence using PGN or standard algebraic notation (SAN), and let the trainer build the position for you.
No complicated setup. No account required.
Step Through Every Move
Once your sequence is loaded, you can navigate through it at your own pace.
Use the on-screen controls or your keyboard's ← and → keys to move backwards and forwards through the line.
You can also jump directly to a particular move simply by clicking it.
This makes it easy to stop at the exact moment where a critical decision was made and take a closer look.
▶️ Replay the Line Automatically
Want to watch the whole variation unfold?
Hit Auto Play and Sequence Trainer will step through the moves for you.
It's useful for:
- Reviewing opening repertoires
- Studying annotated games
- Following tactical variations
- Teaching chess concepts
- Checking candidate lines
- Replaying positions from your own games
Instead of repeatedly setting up the board, the sequence stays right there in front of you.
🔍 Analyse Any Position With Stockfish
The real power comes when you want to go beyond simply replaying the moves.
At any point in the sequence, you can choose Analyze with Stockfish and investigate the current position.
That means you can replay a line, pause at a critical position, and immediately ask:
"Was this actually the best move?"
It's a natural workflow for understanding chess rather than simply memorising moves.
🔗 Share a Sequence
Sequence Trainer also makes it easy to share a particular line.
Use the Share button to create a link to the sequence, making it simple to send an opening variation, tactical line, game fragment, or study position to someone else.
You can also open the sequence in Review when you want to continue analysing it using Chess Move Chooser's broader analysis tools.
🎯 Built for Chess Study
Sequence Trainer isn't trying to replace a full chess database or overwhelm you with dozens of features.
It's designed around one thing:
Put a chess sequence on the board and make it easy to understand.
That makes it useful for players of all levels.
Beginners
Follow a line slowly and see exactly how a position changes after every move.
Club Players
Review opening variations, analyse mistakes, and investigate critical moments from your games.
Coaches
Create move sequences that students can step through themselves instead of simply watching an explanation.
Advanced Players
Load specific FEN positions and variations and use Stockfish to investigate the positions that interest you.

That means you can go straight from a chess position to analysis without getting your way through another login screen first.
From Opening Lines to Endgames
A chess sequence can represent almost anything:
1. An opening
Load a theoretical variation and step through it move by move.
2. A tactical idea
Stop at the critical position and use Stockfish to explore whether the combination works.
3. A game you've played
Reconstruct the important section of your game and investigate where things started to go wrong.
4. An endgame
Load a specific FEN and work through the continuation without having to manually recreate the position.
5. A lesson
Give someone a sequence and let them explore the position themselves.
Your Chess Board, Your Pace
One of the advantages of studying a sequence interactively is that you're not locked into someone else's pace.
Go forward.
Go back.
Jump to a move.
Flip the board.
Play the line automatically.
Stop and analyse.
Then continue.
The board becomes a timeline for the game rather than just a static position.
