This is a challenge of remembering the exact position of the chess pieces in midlegames/endgames after having 10 seconds to memorize them.

I was inspired to do this after coming across some studies that reached the conclusion that masters can recall more pieces than a begginer, if, and only if, it's a typical, possible and legal position.

The studies in question:

• Recall of random and distorted chess positions: Implications for the theory of expertise
• Recall memory for visually presented chess positions
