The diagram shows [[Vladimir Lenin]]–[[Maxim Gorky]], Capri 1908,<ref>{{cite web |url=http://www.chessgames.com/perl/chessgame?gid=1387603 |title=Lenin vs. Gorky, Capri 1908 |website=[[Chessgames.com]] }}</ref> with White to move.<ref>{{cite web| url = http://budchess.sweb.cz/s&p.htm| title = Chess games played by Communists}}</ref> Black is threatening the following rook sacrifice and {{chessgloss|forced mate}}:  
:27...Rh1+ 28.Kxh1 Qh2{{chessAN|#}}

White cannot play 27.gxh3, because the queen on g3 is pinning the pawn to the g-file. The only move that postpones the mate is 27.Nf4, which temporarily blocks Black's bishop from protecting his queen, but to no avail as Black can simply play 27...Bxf4 renewing the mate threat. Or, Black can respond by mating a different way:  
:27.Nf4 Qh2+ 28.Kf2 Rhxf3#

In this case, White cannot capture 29.gxf3 because the queen now on h2 pins the pawn to the 2nd rank. With mate being inevitable, White resigned after move 26.
