This is a correspondence game I played last month with a triple sacrifice of the rook and both bishops. Stockfish needs quite a high depth to confirm that 26. Rxf6!! along with 27. Bb4!! is indeed the winning move - the quick game analysis marks it as a blunder.
To be sure that I could indeed play 26. Rxf6, I had to calculate several complicated variations like 27. ... Qxb4 28. Qxh7+ Kf8 29. h3!! (with Be2 and Bh5 etc. to follow later) or in the game continuation, if black does not play 28. ... Qxh7??, which leads to a forced checkmate, but instead plays 28. ... Kg7, that 29. Bg6!! is the winning move. If black plays 29. ... Qxg6 then 30. Bf8 wins the queen, after 29. ... Qg8, there will be mate in 7 after 30. Qg4.
