Chess openings principles


I can only think of one opening principle.
Develop your pieces more quickly than your opponent.
If you can figure out a way to do that then you have won the opening battle.
"... For beginning players, [Discovering Chess Openings] will offer an opportunity to start out on the right foot and really get a feel for what is happening on the board. ..." - FM Carsten Hansen (2006)
