Declarer counts 8 sure winners : one in ♠, three each in ♥ and ♦, and one in ♣. The 9th trick can come from an indirect finesse in ♣, which has a 50% chance of success. A much better option is a double finesse in ♠. This has a 76% chance of success. Declarer therefore wins the first trick in his hand with the K♥, then leads a small spade to Dummy's 10♠. South wins the trick with the K♠ and leads his 10♣ at trick 3. Declarer must refuse the ♣ finesse, win with his A♣ and then lead another spade to Dummy's J♠. The Jack wins and after leading the A♠ Declarer notices that Opponents' ♠s were split 3-3. The contract is now secure, Declarer's 7♠ even providing an overtrick. Previous - Lesson 15
