by coach Dan Heisman (NM *, FIDE CM *):

• "Time management is an important part of your game!"
• analytical error
• lack of knowledge error
• "There is also a grey area, which we can call >>>visualization error<<< that is when you are looking at a position, analyzing it, but you can't clearly see it in your mind."
