Once you can play, you'll find my material worth viewing. It is 99 percent labor and 1 percent natural. A pointless check only to postpone defeat is known as a spite check. It raises eyebrows. There's a funny chess saying I want to share with you.
Most beginners tend to give check at every opportunity.
You lose tempo if the checking piece is forced to retreat. You must have a good reason for doing this. Winning material or forcing a checkmate will make a point. You might not realize how precious tempo is. It's like allowing your opponent to have two moves in a row.
