Welcome to Checkmate Champ, an interactive chess training tool. Your goal is to find the sequence of moves that leads to checkmate. After you have solved the current problem, click >> to go to the next problem.
To find out about new features and new puzzles as they are added, please follow us on Twitter at @CheckmateChamp.
Instructions
Choose a position from the drop-down box. Your goal is to place your opponent in checkmate. If the text says "White mates in X," you are playing as White. If the text says "Black mates in X," you are playing as Black.
If you make a mistake that allows your opponent to escape checkmate, the status will change to "Incorrect." Click "Reset position" to try again. When you have found the solution, the status will say "Checkmate!" You can then select another position for more practice.
If you get stuck on a problem, click "Show hint" to see which piece you should move. If you still cannot figure out the solution, click "Show solution." The computer will then switch sides with you and play the solution against you. (The sides remain switched like this until you select a new position.)
To speed up moving through the positions, the buttons labeled << and >> will take you to the previous and next positions respectively. You can also click the dice to choose a random position. Positions that you have solved are shown with a checkbox (☑) next to them.
