Problem

The Auction:

North opens the auction with 1♠, South responds with 1NT. North’s rebid – 2NT shows 17-19 HCP, so it is not surprising that South bids 4♥. What is a bit surprising is that North asks for the aces next with 4NT. South answers 5♥, which becomes the final declaration.

We invite you to take the seat of South. Can you see a road to 11 tricks? West leads the ♣Q.

Contract: 5♥S

Vulnerable: none
