Magnus Carlsen has yet to solve this Chess Puzzle. Can you?!
To be fair, the reason Magnus Carlsen has yet to solve this chess puzzle is because he hasn't seen it yet. That said, "fair" is not really a term I'd used to describe this ridiculously difficult study. "Insane", perhaps, "cruel and unusual" might apply as well.
In any event, solve at your own risk...
