To replay a commented Beginner Chess Game helps you to understand chess principles. I commented the mistakes in the chess games below and I hope that you do understand my comments and that they help you to make better chess moves in the future.
In the following game many mistakes are made by White who is a beginner. He just knows how to move the pieces around but he has no idea about development and which pieces to develop first.
He does not develop the kingside pieces and brings his queen out to early. He wastes development time in moving pieces a few times in the opening. All those mistakes add up and finally lead very fast to a lost position.
In the following beginner chess game the beginner is Black. He just moves pawns and wastes development time but does not develop the kingside pieces until his king remains stuck in the middle.
Next game the Beginner is White. He moves out his Queen too early. Black keeps attacking the white Queen and develops pieces as fast as possible until the enemy king remains stuck in the middle and gets mated.
