Although the term ''Plachutta'' is confined to the world of chess problems, not being used in a wider chess context, the underlying Plachutta pattern does occasionally (though rarely) appear in an actual game. One example is to the right, a position which occurred in a 1914 game between [[Siegbert Tarrasch]] (with white) and a team of opponents consisting of Davide Marotti (who became the champion of Italy in 1921), E. Napoli, de Simone, and del Giudice.<ref>[[Edward Winter (chess historian)|Edward Winter]], [http://www.chesshistory.com/winter/winter38.html#5161._Tarrasch_v_the_Allies ''Chess Note'' 5161] (2007-09-15). Retrieved on 2009-08-20.</ref> In the diagrammed position, the black queen defends against Qb7 and the rook on c8 defends against Rxc5. Tarrasch played 31.Bc7!, a Plachutta interference after which black cannot maintain control over both b7 and c5 (Black actually resigned after this move). If 31...Rxc7 the rook is overloaded, having to look after both the key squares: 32.Qb7+ Rxb7 and the rook is deflected from defence of c5, allowing 33.Rxc5#. If instead 31...Qxc7 it is the queen which is overloaded: 32.Rxc5+ Qxc5 deflects the queen from defence of b7, allowing 33.Qb7+ Kxa5 34.Ra1#.<ref>[[Julius du Mont|J. du Mont]], ''The Basis of Combination in Chess'', Dover, p. 180. {{ISBN|0-486-23644-7}}.</ref><ref>[[John Littlewood (chess player)|John Littlewood]], ''How to Play the Middle Game in Chess'', Collins, 1974, pp. 110-11.</ref>
