Forks and Skewers

This is a mini-game to practice the most common tactics: forks and skewers. It is popular with children starting out.

The bishops have the first move. You win by capturing one of your opponent’s pieces. This game is a draw with best play but in practice mistakes are made.
A fork is when a piece attacks two other pieces simultaneously.

A skewer arises when the attacked piece is on the same line of attack as one of its colleagues. Only the first in the line is attacked but if it moves out of the way, then its colleague can be captured.

From the starting position it is possible for the rooks to go wrong.

In the above diagram, the rook on h8 is under attack. Where to go?

Black has made a serious error (marked by the “?”). White can now fork the two rooks.

Both of Black’s rooks are under attack and only one can be saved. White wins because it is the first to capture an opponent’s piece.


Modify the winning condition so that for the rooks to win, they need to capture a bishop safely i.e. without a rook being immediately recaptured. This rule compensates for the fact that the rooks are stronger pieces than the bishops.


Playing this game with clocks has a significant effect on performance. Normally the game should be drawn. However, if the players are under time pressure then one of them will inevitably make a mistake.
