After LHO leads ♠Q, RHO cashes ♠AK then exists with a heart. I drew the trumps, cashed the clubs and then played ♦J. LHO produces the 2. I played the king and that was one off.
Of course LHO had the queen. No else went down in 3♥. The opponents insist that I need to take the diamond finesse ... I guess they mean "against the queen" rather than "against the ace". But ... why? Why is the finesse against the queen better?
Or shouldn't I be taking no finesse at all?
