Hi,
Hope everyone is having a great time in the new year and enjoying playing your games 
Surely you know a number of moves you know you should never ever make during the first few moves, such as:
blocking your Queen and Bishop with your Knight in the second move or blocking the development of your Knight with a not so wise Pawn move.
Some such seemingly insignificant moves may end up in losing the game in less than 10 moves!
Watch out and stay wise
What are the worst opening No! No! moves you know?
Thanks for sharing
and have a great time playing chess wisely
