Pirate Chess in Skull Cove

A new take on the Pirate Chess Set 40158 that I fondly remember playing with about seven or eight years ago. I have created two sides, per the usual, and both seem to be thinking that they have the upper hand. It's going to take some savy swashbucklers to beat the elite Royal Guard. Can they do it and escape with the beached treasure? Only a checkmate will tell...
