Are you double pawns?

When you have double pawns that tends to lead to a weak game.  Double pawns is generally known when you have two pawns that are directly in front of each other.  This will result in an early capture.  Not only does it result in an early capture, but the double pawns will become the isolated pawns.  This means that your pawns will not be able to be defended by other pawns nor will the be able to guard.  So, if you have two pawns on the game board that are in the a vertical file and do not have the ability to have a guard with one another, then this major weakness will begin to haunt you towards the end of the game!
