Among the purposes listed for chess sacrifice in Chess Sacrifices as Chess Tactics, this is one of the most frequent of such uses and may occur sometime or other in a majority of chess games. The lines of attacks that are opened are usually diagonals for Bishops or files for Rooks or either type for the Queen. It is also common occurrence to see a sacrifice of a Bishop to open files for Rooks or Queen, and sacrifice of a Rook to open diagonals for Bishops or files for other Rook or Queen. In certain circumstances, even the Queen may be sacrificed if that brings a quicker checkmate by allowing easy passage for other pieces along the opened lines. Of course we are not excluding the sacrifice of pawns or Knights from the ambit of such chess tactics.

You need not think that such an attacking tactics ends with sacrifice of a Bishop or a Rook or something simple like that. There are famous attacking games involving double Bishop sacrifice or double Rook sacrifice or sometimes even more. Cornering the opponent’s King is the ultimate aim, so the attacking player can afford to give up everything that can clear his way to that goal.

The game used as example here shows a double Bishop sacrifice to open lines for Queen and Rook. It was played by Koltanowski against Defosse in the 1936 Belgian Championship match held at Ghent.

Georges Koltanowski (1903-2000) was awarded IM titile in 1950 and honorary GM in 1988. He was a Belgian Champion, but later moved to USA and became the President of USCF from 1975-1978. Marcel Defosse was the pseudonym of Denis Marion (1906-2000) who was noted as a literary person with a passion for chess. He co-authored with Frits van Seters a book titled “Le Jeu d’Echecs. Manuel du Débutant” (The Game of Chess: Guide for Beginners) published in 1945.

The diagram shows the position at the end of 19 moves.
