Every day you can trouble your head with new chess problems of the following types:

• Daily Chezzle
  
• Best move Chezzle
  
• Mate in 2 or more moves
  
• End game Chezzle
  

Our Mondriaan is a palette of 64 colourful Chezzles. A new Mondriaan is published every month and you are challenged to solve all 64 of them within the month. The best Mondriaan solver will find a place in our Mondriaan Hall of Fame.

Pick a field, study the problem and select one of four possible answers. A good answer marks the field green, a wrong answer red and open puzzles are marked orange.
