Here is a short kings gambit declined game I recently played as white on chess.com. The time controls are 30 minutes each. With quick development and a little luck my opponent resigned in less than 11 moves. Due to a few minor mistakes by my opponent I was able to deploy my pieces very quickly. With the initiative and quick development you can keep the pressure on a vulnerable king rather well. I think this game is quite beautiful and therefore is the reason I really like playing in Paul Morphy’s style.
In conclusion, at the prospect of losing his queen for a knight my opponent resigned on his 11th move. I find that this game shows the importance of quick development of your pieces and also how to take advantage of a king in the middle. Finally I hope you have enjoyed my short kings gambit declined game.
