Share your favourite puzzle (and tell us why)

Every player has one puzzle they never forget — a stunning sacrifice, a quiet move, a study that looked impossible.

Post yours here:

• Use ♟ Position to add the board (FEN)
• Say whose move it is and the goal ("White to move and win", "mate in 3")
• Put the solution in a reply starting with SPOILER so others can try first

Screenshots and diagrams from books are welcome too (please say where they come from). Let's build the best puzzle collection on the internet! ✨
