White to move — find the best continuation
Solution & explanation
Main line
21. Re8+ Kd7 22. Qxd5+ Kxe8 23. Qe6+ Kd8 24. Bf6#
Why it works
- Best move. rook to e8 is exactly what the engine plays (#3).
- Spot on — queen to d5 (#2).
- Precise: queen to e6 is the top choice (#1).
- Best move. bishop to f6 is exactly what the engine plays (#).
- The line ends in a forced mate in 4.
- If instead Kd7, then Qxd5+ and you stay on top.
