Candidates Tournament 2020-2021: Caruana Fades, Nepo Comes On Strong
(These are the standings before today's games. I think it's going to be Nepo who wins the right to challenge Carlsen for the world title.
Intermediate Problem - Black To Play (1351)
Goal: Black can force mate in 5 moves
Hint: Eventually, the rook on f8 is going to have to come down

Note: that cryptic line of letters and numbers you see underneath each board diagram is a representation of the position in what is known as "Forsyth-Edwards Notation", or F.E.N. It's actually readable by humans. Most computer applications nowadays can read FEN, so those of you who may want to study the position, you can copy the line of FEN and paste into your chess app and it should automatically recreate the position on its display board. Or, Windows users can just "triple click" on it and the entire line will be highlighted so you can copy and paste it into your chess app.
