North won the bid at 4 hearts. When South laid down his dummy hand, South had 4 of the top 5 hearts. Is the North-South team eligible to declare 100 honors even though North won the bid and South had the honors?
Yes. Either hand, by either side, may claim honors. The only restriction is that the honors claimed must all be in the one hand. This has been the rule since before I first learned the game in 1963.
