Pferdeaeppel

Pferdeaeppel is a tactical 2-player game. It is fast and easy to learn. Each player controls a horse and tries to either capture their opponent or make their opponent's piece unmovable. The horses move just like in chess. The twist is that each time a piece is moved the prior spot it occupied is marked. Marked spots can no longer be moved into, so eventually somebody gets stuck (or captured). - BoardGameGeek
