The position of chess and draughts in some European countries after 1500

 Two positions where the same huff trick brought the victory.

  The position on the diagram left occurred in a game played by two French players in the late 19th c. "I have won the  game", the player with the four black kings said. His opponent refused to surrender. "Please make your move", he replied. Black played 1. 48-39, White's reply was 50x20. Black did not look to White's move; he expected 50x15 and immediately played 2. 16-38. Now he is lost: White huffed the king on 47 and took the king on 38: 15x47!

 The position right came on the board during a game played in Nice (France) in 1907. It is a drawn position, but White, a Dutchman living in France, took a risk by trying a trick, playing 1. 6-28. Black, a Frenchman, wanted to catch the white king: 1...41-46 2. 28x10. History repeats itself: Black expected 28x5 and played without looking to White's move 2...27-32, and saw his king huffed and his piece taken. The Dutchman's knack worked!
