Your task: North's 3 shows a singleton or void heart. You (South) hold AQ3 — two honours in North's short suit. Are these values working or wasted, and what do you bid?

Solution

Sign off in 4. Your AQ are wasted opposite a singleton or void.

Jacoby 2NT asks opener to describe shape, not points — and a new suit at the 3-level is opener's way of showing a singleton or void there. North's 3 does exactly that.

Why AQ3 doesn't help

Opposite a singleton or void, the ace and queen of hearts can take at most one trick between them — often none, since North can ruff a losing heart after the first round. 14 HCP looks like slam interest on paper, but a big chunk of it is sitting in the wrong place.

What would change the picture

If South held small hearts instead (say 72), there would be nothing to waste — every card elsewhere in South's hand pulls full weight opposite the shortness, and a slam try becomes very much worth exploring.

Key point: After a Splinter or Jacoby 2NT, check where your honours actually sit before valuing your hand. Points opposite partner's shortness are often points that don't take tricks.
