In a club teams match Declarer is on lead from dummy playing in a heart contract. He claims conceding a trump in this end position. Dummy ♥1085 ♦5 - opposite a ♦winner and 3 cards. Declarer thinks the trump out is the ♥J. It is in fact the ♥7 and is sitting under the 1086. Do you award 3 or 4 tricks to declarer?
