LEAD WITH THE ACES

ANSWER: As a passed hand, you can now jump to two hearts to show five hearts and four-card diamond support, a fit jump. You have a dead minimum for this action, but the concentrated values more than make up for that. There is absolutely no point in playing jumps by a passed hand as weak. With that hand, you would have preempted initially, or you would bid the suit at a minimum level now, rather than jump.
