This is a game from 1914 between Bernstein and Capablanca. With black to play the position looks fairly even and many players might settle for a draw. Settling for a draw as black is definately not the right decision though, 1 move later by Capablanca and Bernstein resigned.
If you study the possibilities after the winning move you will realise that resigning was the most logical option.
