The art of good defence
Keeping all of your pieces protected will promote safety and give you peace of mind. Often we have a tendency to advance our pieces deeper into enemy territory without worrying too much about safety. A general rule of thumb which is especially important to remember for amateur players is too keep pieces defended by another piece or pawn unless it is safe from immediate threat. That will minimise the possibility of a quick fork, double attack or skewer - Chessworld.com
