Game of the Week: Prince of Persia and the question of memory tax

I think I first heard the term memory tax when I was writing about chess. In chess, at the really great levels of play, memory tax is a huge part of what you're dealing with.

You have to remember whole openings and end-games, and remember how to counter this kind of move, and where that will leave you, and how to regain tempo. Lots of memory tax is chess!
