Your Queen is Not Wonder Woman

Every decent player knows not to bring out your Queen too early but a lot of players use their Queen as if she's Wonder Woman.  Of course what happens - she gets nabbed.  Then there she is in the bad guy's secret hideout all alone in the dark and useless.  Learn how to use all of your pieces in co-ordination.  In the long run if you don't you can be sure you will be handed your hat.
