The basic on openings:  

Center, development of the pieces and king safety (castle)

The basics of each phase of the game

Opening:

Follow the Opening principles:

1. Control the center squares – d4-e4-d5-e5

2. Develop your minor pieces toward the center – piece activity is the key

• Complete your development before moving a piece twice or starting an attack.

• Move pieces not pawns.

3. Castle

4. Connect your rooks

• By move 12, you should have connected your Rooks, or be about to do so.

Middle game:

When you have completed the Opening Principles, you are now at the middle game. Now you need to formulate a middle game plan. The middle game is a very complicated part of a chess game. A simple way to develop a middle game plan is to perform the following steps.

1. Scan your opponents 5^th, and 6^th ranks (3^rd, and 4^th if your black)

2. Look for weak pawns, and or weak squares.

• Weak pawns and squares are Pawns, and squares that cannot be defended by another Pawn.

• Knights are excellent pieces on weak squares.

• When deciding on weak squares, and weak Pawns to attack, the closer to the center the better

End game:

Start with the basics:

1. Learn basic mates – KQ vs. K, KR vs. K, KRR vs. K

2. Learn Opposition, and Key Squares

3. Learn basic King and Pawn endings
