Baron Slam Try

Used to invite partner to slam if partner holds good trumps (good trumps depends upon previous auction).

The invitational bid is the first suit below the agreed-upon suit and one bidding level below the desired slam. With poor trumps partner responds by signing off at the cheapest level, with good trumps partner jumps a level.

For example, if spades are the agreed suit, 5H invites 6S. If hearts are the agreed suit, 6D invites 7H.
