3. A♥, 5, 4, 2♦.
4. K♥, J, 6, 5♦.
5. 2♣, 6, Q, 3.
6. K♣, 4, 6♠, 8.
At this point, declarer faces his hand and claims "conceding two diamonds".
North agrees "one down", all players shuffle their hands, before the player who was dummy says "you're ruffing that second diamond!".
The director is called. The bidding and the play up to the claim are undisputed. Your ruling?
