The following position is from Ding Liren versus Wesley So in 2016. I was studying the Catalan Opening, and I came across this incredible position. I felt like white had to have some kind of attack, but Stockfish said no. After forcing Stockfish to think for several minutes, it finally came up with this wonderful solution.
It is white to play. Can you find the unusual sacrifice? I will post the answer next week.
