Chess Basics

1. Control the Center (E4, E5, D4, D5)
2. Develop your pieces towards the center
3. Develop knights before bishops before they are slow.
4. No unnecessary pawn moves. They are a loss of time and will help the opponent develop faster.
5. Bishops on longest possible diagonal.
6. Queen should not be developed too early. Try to develop with minor pieces first.
7. Always Castle to make your king safe. And it also helps to develop rook to the center.
8. Rooks are good on open files. Try to get rooks on the 7th and 8th rank so they can capture the pawns.
9. Checks, captures, and threats. Especially when the king is exposed do not miss considering a check.
10. Place your pieces on effective squares.
11. How to deal with bad bishops - Exchange it, change the color of your pawns, bring him outside the pawn chain.

    Closed Center. Knights are good in closed positions.
15. 
    Open Center leads to more attacking and interesting positions. Bishops just dominate the knight in open positions. Try to obtain a pawn chain that favors your bishops. If you have a light square bishop try to obtain a dark square pawn chain.
