Basic chess course:

 From scratch till Grandmaster.

Lesson No.1: Capture the king and win!
Next lessons:



Notes:

  • Only knights may jump over pieces or pawns.
  • Castling is a king movement. He moves always two squares, left or right.
  • Castling is a good move to bring your king in safety.
  • It's forbidden to castle either when the king or concerning rook has moved at least once.
  • It's forbidden to castle when the king is currently in check.
  • It's forbidden to castle when the king passes an attacked square.
  • It's forbidden to castle when the king would move into check.
  • Capturing a pawn 'en passant' may happen only at the very next turn.
  • Checkmate finishes the game. You don't need to capure the king at the next move.
  • The game is finished when one player resigns.
  • When you're not in check and can't do any move, without getting checked, it's a draw by stalemate.
  • A draw is forced by three times exactly the same position,
    with the same options in the position, like e.g. option to castle or capturing en passant or not.
    Also the rooks or knights may not have switch positions.
  • It's a draw when both players aggree to.
  • It's a draw when there's a lack of material to checkmate opponent.
  • It's a draw if 50 moves are played, without capture or pawn movement.






    Lesson: Experienced chess players build their own opening repertoire.
    Choose an opening you like most, persist playing and improve it,
    till it becomes a part of you.

    It's all about controling the center.
    Develop your pawns and light pieces for this purpose.
