One piece will move. Spot which.
What Moved
What Moved trains you to notice change on the board. A position of eight pieces is shown for three seconds, then shown again with one piece standing on a different square. Tap the piece that moved. There are ten rounds, and after each one the page shows where the piece came from.
How to play
- Press Start and look at the position for three seconds.
- When the position changes, tap the piece that now stands on a new square.
- The page marks the square it moved to and the square it came from, then you go on. After ten rounds you see how many you spotted.
Questions
- Why is this useful?
- After every move of your opponent the first question is what changed: which squares the piece left unguarded and which it now attacks. This game drills the first half of that habit, seeing the change at all.
- Is the change a legal chess move?
- Not necessarily. One piece is lifted and put down on an empty square, wherever it is, so that you have to look at the whole board.
- Can I see the first position again?
- No. It is shown once, for three seconds.
