You can do this if West has exactly five hearts and East’s singleton is the jack, nine or eight. When it is the jack, a low heart to the king would establish the ten and you would have the necessary four tricks in hearts. As it is twice as likely that the singleton will be the nine or eight compared to a jack that is what you should play for. Suppose the full deal is:
