Chess, Complexity, and the Art of Solving Hard Problems

A less talented chess player looks at the position, miscalculates everywhere, gives up and goes, 'well idk, White must be losing.'

An advanced player knows what they're doing -- and clearly, White is winning.

A tiny handful of players say hmm, something seems off here, and they get great joy out of looking for that random little detail, and that detail wins them the game.

The real world seems more like chess than checkers, and most of us aren't that good.
