Double Attacks but not Forks-- OTB Examples
Compiled by ChessCoachClark
--*--

The Double Attack and the Fork are not synonymous. Every Fork is a Double Attack, however. In the interests of clarity, the term Fork is being applied to any chessman that attacks two or more chessmen in the same ply. The Double Attack is the more general term, being applied to two chessmen attacking the same target or two chessmen attacking two targets or one chessman attacking two targets.

IM Daniel Rensch is far more restrictive when defining the Fork and Double Attack-- the Fork is only that tactic made by a Knight or a Pawn and the Double Attack is the category for all of the other chessmen (at Chess.com and videos for children).

So, I will respectfully disagree with him and express gratitude to the majority of chess masters and writers who make the more common definitions the norm. Any chessman has the power to make a Fork and a Double Attack as well.

"The Fork is the simplest example in chess of the 'Double Attack' type of combination. Any piece can Fork; even a King often attacks two men simultaneously in the later stages of a game." British chess champion Leonard Barden
AN INTRODUCTION TO CHESS MOVES AND TACTICS, SIMPLY EXPLAINED
Page 76.

(A more rigorous definition of a Combination may be in order, but the Fork and Double Attack usages by Barden are fine.)

So, the Fork is a special case of the Double Attack and most certainly among the top three most important tactics. As the Knight and Queen could theoretically make seven-way Forks, there are possibilities of 'Double Attacks' on more than two chessmen.

Of course, any game having a Double Attack bringing checkmate is a treasured jewel for everyone.

Some writers have also used Double Threat and Two-Pronged Attack for the Double Attack. There are probably other colorful references in the chess literature as well.

Here then is a my partial list of games that demonstrate two or more attacks (even an attack on a square) on chessmen.

ChessCoachClark (CCC) originated this game collection and he updates it on occasion. This project is a work in progress, culling games from various sources, including several chess training books and personal research. The games are ordered by date (oldest first), not by importance.
