Imagine if Stockfish, the strongest chess engine ever built, had been studying your games. Imagine if every grandmaster in history had been watching them with you. Not chess in general. Your games. Your patterns. Imagine if you could ask them what they think?

Now you can.

Not just another AI

The AI does the talking. The engine does the chess.

Language models are wonderful at conversation and unreliable at chess: they will confidently invent a move that loses. So the AI does only what it is brilliant at, understanding you and explaining clearly, and every move, evaluation, and line is checked by Stockfish, the strongest engine ever built. Grounded, not guessed.

Personal, not generic

It does not teach you chess. It teaches you your chess.

Connect your account and it reads every game you have played. It finds the patterns that are actually costing you, the bishop you keep trading off, the openings you drift in, the endgames you let slip, and it tracks them over time. No rating-band platitudes. The work is yours, drawn from your own board.

The research agrees: the strongest predictor of chess skill is not talent, and it is not playing more games. It is serious, directed study (Charness et al., 2005). MySecond exists to make your study hours the right ones.

Three coaches, three ways to be taught

Choose the voice that gets the best out of you.

Katya

Warm and encouraging

She scaffolds. A hard idea broken into small steps, your confidence built as your skill is.

Marek

Blunt and direct

No flattery. Deliberate practice: the honest truth about your game, then the reps until it sticks.

Dimple

Patient and Socratic

She rarely hands you the answer. She asks the question that makes you find it yourself.

What it does for you

Everything a real coach does, built around your game.

It knows your game

It reads every game you have played and tells you what it sees, the way a coach would: your patterns, your progress, and the one thing worth fixing next.

It plans your growth

A weekly plan built from your own games, one idea at a time, in the order you are ready for. Taught from a real book, then tested on your board.

It teaches you how to think

On any position it walks the thinking with you: how to find the move, not just which move. The judgment calls, taught as judgment calls.

It debriefs every game with you

Finish a game and walk back to your corner: your second was watching. Sit down for fifteen minutes on the game that mattered, in a real conversation that remembers the last one.

Underneath: structured lessons, drills built from your own mistakes, an opening trainer, play-the-coach when you have no games to import, a study desk that walks any public Lichess study with your coach narrating, a coach that notices a slide or a tilt and speaks up first, and a think-aloud mode that lets it hear your reasoning while you play. All of it kept honest by the strongest engine and real chess books, so what you are told holds up.
