Chess tactics

1. Move defensively as much as possible. Don’t move pieces and pawns to squares where they can’t be defended immediately. Don’t expose your strong pieces to attack by weaker enemy pieces.
2.  Do not make pawn moves without careful planning
3. Complete your development before moving a piece twice or starting an attack
4. Open with either the e-pawn or the d-pawn.
5. Wherever possible, make a good developing move which threatens something or adds to the pressure on the centre.
6. Develop knights before bishops.
7.  During the first few moves, pay special attention to the vulnerable KB2 square on both sides
8.  
9.  
10.  
11.  
12.  

1. More detail on winning the race:
   • move pieces not pawns, and
   • move them to their best squares in one move if you can, and also
   • try to gain time if you can by aggressive moves.
