Problem

The Auction:

* Cappelleti

North started with 1NT, East overcalled 2♦ – Cappelleti – 11 HCP, 4+ spades and 4+ hearts. South passed. West responded 2♠. North, who held four spades, passed. East passed too. South came to life and bid 3♦.

After a bit of thinking – as East/West had found a fit, an 8-card suit of spades, West doubled.

West led the ♥4. How can South win 9 tricks?

Vul: Both

Contract: 3♦ Dbl by South.
