A 60-second drill to memorize the chessboard.
e4 or c7.Chess strength sits on top of a quiet, almost invisible substrate: instantly knowing where every square is. Strong players never “hunt” for a square — when an annotator writes 22. Nxf6+ Bxf6 23. Qd2, the squares simply appear in their mental image of the board. Players who have not yet automated coordinate recall spend cognitive load doing what should be automatic, which is cognitive load that should be spent on the actual position.
This trainer attacks that one specific bottleneck. Sixty seconds, randomly chosen squares, immediate feedback. The drill is short enough that you can run it before each study session as a warm-up, and the timer makes the practice intense enough that you cannot fake your way through it with slow, deliberate counting. The same mental motion is what blindfold-chess players rely on entirely, which is why coordinate fluency is widely recommended as the first step toward serious visualization work.
Treat the trainer like a daily warm-up, not a final exam. Three rounds at the start of every study session is enough to build coordinate fluency over a few weeks; an hour-long marathon will exhaust you without producing better results. Aim for accuracy first, speed second — a square misclicked in practice is a square that will be misread in a real game under time pressure. Once your three-round average crosses thirty correct with ninety-percent accuracy, alternate the board orientation between rounds so the recall remains symmetric. Some players find it useful to say each target square out loud as they tap it; this links the spoken-notation and visual-position channels so reading a PGN aloud later becomes effortless.
Chess players who already know the rules and want to read notation faster, follow annotated games without losing the position, and develop the board-vision required for calculation and blindfold play. Beginners can use it from their first week of play; club and tournament players use it as a warm-up before serious study.
Yes. The board fits the screen on phones, tablets, and desktops. There is no app to install and no account to create. Tap-to-select is the only interaction.
Each round is exactly sixty seconds. Three rounds, two with White at the bottom and one with the board flipped, takes about three minutes including summary screens — short enough to do before every training session without it becoming the training session.
Twenty correct in sixty seconds is a reasonable starting target, thirty is a strong intermediate result, and forty or higher is fast even for tournament players. Accuracy matters at least as much as raw score; an accurate twenty is a more useful foundation than a sloppy thirty.
Each round's final score and accuracy are shown on the summary screen but are not persisted to a server or to local storage. The trainer is intentionally session-scoped so the focus stays on the next round rather than a leaderboard.
Most players unconsciously develop the ability to read squares from one perspective and struggle when the position is mirrored. Drilling from both sides prevents that asymmetry and is especially useful before tournament play, where you cannot choose your color.
Time's up! Here's how you did.
