This cache is one in a series of 5. This cache and 3 others (Mate in One - Fianchetto, Mate in One - J'Adoube, Mate in One - En Passant) contain the positions of the pieces in a chess puzzle taped on the back of the logbook. After finding the first 4 caches, you’ll need to figure out the move that produces checkmate for the White side. This move will reveal the missing digits of the coordinates of the final cache, Mate in One – Checkmate!.
zugzwang - A German word commonly used by English-speaking chess players that means a “compulsion to move”. When a player would rather maintain the current position, but must move because it’s his turn.
You'll need to understand a little about chess notation in order to set up the position of the final puzzle cache. A chessboard's squares each have a file (column) letter and a rank (row) number assigned to them. Just like the latitude and longitude you use to hunt geocaches.
The cache is a camo-taped decon container with small trade items and a pencil inside. Bring your own writing instrument just in case though.
I'm not sure if this cache is accessible from Beaver Brook Rd., but I wouldn't try it. It's very easy to get to from the park it's in. There's ample parking. Besides, Lincoln Park Airport is on the opposite side of Beaver Brook Rd. and it may raise unwanted attention if you try and park on the side of the road.
We hope you enjoy this puzzle!
