A position is shown. Count the moves that give check and press the number, as many positions as you can in a minute.
Check Count
Check Count trains the first step of calculating: seeing every check. A real position is shown and you count how many of the side's legal moves give check, then press that number. After each answer the page lists the checking moves. Answer as many positions as you can in one minute.
How to play
- Press Start. The board shows a position and says whose move it is.
- Count the moves that give check, including captures, discovered checks and mate, and press the number from 0 to 5.
- The page tells you the checking moves, then shows the next position. After a minute you see your score.
Questions
- Why count checks?
- Checks are forcing: the opponent has to answer them. Strong players look at every check before anything else, and most missed tactics begin with a check nobody looked at.
- Which checks are easy to miss?
- Discovered checks, where the piece that moves is not the one giving check, and checks by a pawn or by the king stepping away from a line.
- Who decides the answer?
- The rules. Every legal move in the position is generated by the same rules library the rest of the site uses, and the ones that give check are counted.
