Time and development are very important elements of chess. Development simply means that your primary pieces are moved out from the back rank and in a potion to attack. Though sometimes this can be accomplished by leaving them on the back rank, it is not the normal scenario. Imagine that rook that is trapped on the back rank by a knight and a pawn, it has not yet been developed. The player whose pieces are ready for battle sooner will be able to control the tempo of the game. If you want to be that player, you have to develop your pieces efficiently and quickly to powerful positions.
Many inexperienced players like to move many of their pawns at the beginning of the game to control space on the chessboard. However, you cannot win with pawns alone. Since knights, bishops, rooks, and queens can move greater distances than pawns and threaten more distant targets, it is a good idea to bring them out quickly. This of course is after you have moved enough pawns to guarantee that your stronger pieces will not be chased back by your opponent's pawns.
Once all the other pieces are developed, it is easier to see what pawns you should move to accomplish your overall plan. It is tempting to bring the queen out very early because it is the most powerful piece on the board. However your opponent can chase your queen back by threatening it with his or her less valuable pieces Instead of just moving pieces out, try to determine the best square for each piece. Then try to place that piece there in as few moves as possible. This may save you from wasting valuable moves later in the game.
