Chess Square Notation Trainer
A trainer that calls out a square (e4, c6) and asks you to click the right one — so board coordinates become instinct.
Knowing every square on sight is fundamental to improving at chess. This trainer flashes a coordinate (e4, g7, and so on), and you find and click that exact square on the 8x8 board as fast as you can — building both your score and your reaction time.

How to use
- Set your board orientation (white or black perspective) and choose whether to show the rank and file labels.
- Press Start and read the random target square shown at the top (for example, d4).
- Click the correct square on the 8x8 board before time runs out, and track your score and click reaction time in milliseconds.
FAQ
- How do you read chess coordinates?
- Every square is named by combining its file — the columns, lettered a through h — with its rank — the rows, numbered 1 through 8. So e4 is the square on the fifth file from the left, four rows up from the bottom.
- If I switch to the black-side view, does the notation for the same square change?
- No — a square's notation (like e4) is an absolute coordinate on the board and stays the same no matter which side you're viewing from. Only the on-screen orientation flips. Practicing from the black-side view simply helps you get comfortable with the mirrored perspective you'll actually see when you're playing as Black.
