South is on lead in a ♠ contract, in need of 4 out of the last 5 tricks.
He can achieve this goal by leading ♥9 and west has to pitch a ♣, then north ruffs, and leads ♣5, if east plays low, south ducks to west, pitching a ♦, and has west endplayed, if east puts up ♣K, south ruffs, and exits with ♦5, either east or west will concede the last 2 tricks.
Does this interesting end game have a name, or is it a variant to a known end game?
