Chess visualization training
Blunders happen when the board in your head goes blurry. Chess-Sight trains that inner board — real games read aloud, positions rebuilt from memory, progress you can measure.

Start with the Vision Test to find your level, then split time between game playback, position recall, and the tactics woodpecker.
Play through real games — in your head.
Pick a classic or import your own. Moves are read aloud; you play them out mentally, then prove you saw the position by rebuilding it. Turn the jump size up as your vision grows.
Start a game →Hear a position. Rebuild it from nothing.
A full position is read to you, piece by piece. Reconstruct it on an empty board from memory — the fastest way to burn square names and piece patterns into your head.
Try a position →Measure your Vision Rating.
A five-minute test of square sense, knight paths, and blindfold tracking. Get a rating, see where you stand, and get told exactly what to train next.
Get your rating →Drill one set until you can't miss.
Forty engine-verified patterns, repeated in shrinking cycles. Misses come back until you beat them twice; later cycles flash the position and blind the action zone.
Start drilling →Since Adriaan de Groot's famous studies of grandmasters, chess research has pointed at the same thing: strong players don't brute-force more moves — they see positions in chunks, hold them clearly, and update them effortlessly as lines unfold.
That skill is trainable. Every drill here forces your brain to maintain its own picture of the board instead of leaning on your eyes — the same muscle you use when you calculate at a real board.
Clearer board, deeper lines, fewer blunders. That's the whole thesis.
Moves and positions are read aloud with real recorded speech — your eyes stay off the board.
Track the sequence in your head. Start one move at a time; work up to five, then ten.
Rebuild the position on the board. Instant feedback, streaks, and a rating that moves with you.
The board in your head comes before tactics ever click. Square colors, knight hops, and short sequences — drilled gently, read aloud, no timer pressure.
Most plateaus are vision problems wearing a tactics costume. You find ideas but misplace pieces three moves deep. Train the seeing, and the finding follows.
Strong players hold whole positions effortlessly, which frees them to think about plans. Import your own games and replay them from memory until your losses become drills.
Five minutes. Three skills. One number — and a training plan to move it.
