Reviewed from Black's side by the ChessCoda Coach Engine, exactly as it reviews your games. Explore the board freely; the review pauses while you look.

Twenty-four opponents. One of them is your level.

Each plays like a real person at their rating, with a style of their own: attackers, tricksters, grinders, strategists. Play them in the iPhone app. Play Coda right here.

An example report

Meet your AI Coach

Not a score. Not a centipawn. A clear explanation of what happened in your game, and what to do about it.

CoachMove 18, middlegame

Your knight on d5 was doing two jobs: blocking the e-file and covering c7. Trading it with 18.Nxe7 gave both up at once, and the rook invaded two moves later. When one piece holds your position together, think twice before trading it.

CoachMove 31, rook endgame

Down a pawn here, the real mistake was trading rooks. The pawn endgame is lost, but with rooks on the board your active king gives real drawing chances. Keep the pieces that keep you in the game.

CoachGame summary

You came out of the opening better in all three games this week, then drifted around move 20 when there was no obvious plan. Next time, pick a target before you push pawns. That's what we'll work on.
