Competition Problem 112b

South to make one heart against any defence.
Successful solvers: Jean-Marc Bihl, Steve Bloom, Leigh Matheson, Radu Mihai, Sebastian Nowacki, Andries van der Vegt, Dick Yuen, Wim van der Zijden. Tables
This is more of a demonstration hand than a problem, but my (b) problems are supposed to be easy and I thought solvers might at least find it amusing. I've made an executive decision to give it the lowest difficulty rating without looking at solvers' suggestions.
West does best to play three rounds of hearts. North and South both play high on the first two. North plays the ♥4 on the third and South overtakes unless East discards a third spade. If North is now on lead, then the spades can be set up with two ruffs and declarer makes four overtricks. Otherwise East has discarded two spades and either a diamond or club and declarer can establish a winner in the minor suit from which East has discarded, yeilding just the seven tricks required.
