Chess Rematch Traditional Cache

We had a cache here a while ago, but we were beaten at our own game and the container kept coming up missing.  We accepted our loss, but have come up with a new strategy and have replaced the cache with one we believe will be a game winner.

Some of the things we love about parks are the large fields to run and throw a ball around in, or the playgrounds to swing and slide down.  This park has all that, and is the only one we have seen in the area that also has chess boards to challenge yourself with.  Bring your own pieces and sharpen you mind as you play against a freind, or maybe meet someone new to flex your prefrontal cortex muscles on.  Did you know the word “checkmate” comes from the Arabic word “shah mat” which translates to “The king is dead” in English.  See if you can translate the mystery here to find this challenging cache.
