Online Mate In One Test

Test your ability to solve mates in one using this fun web application. You get 10 seconds to find the correct move. If you're right, then you immediately get another position. The program stops when your move is not checkmate, or when your time expires.

Many of the positions are trivially winning, but the goal is to checkmate in one. Multiple solutions exist for some problems, and the program will accept any of them. After you have solved several hundred, you may notice that some positions repeat.

Parental warning: This game is addictive. I know several young masters who solved over 100 in a row. At least two have reached 500! At this time, yours truly only achieved a modest 41. If you wish to brag to your friends, then save a screenshot immediately after you messed up.

Finally, if 10 seconds is too fast, then simply edit the number at the end of the URL.
