1. Do not exchange your B without a good reason.
2. Develop your Pieces quickly.
3. Do not waste moves by moving too many pawns in the opening.
4. To win in a better position, try to play forcing moves and calculate sacrificing material to get an attacking.
5. Attack the Pin again and again.
6. Try to bring all your Pieces to the Attack.
