Leaping Michaels

Leaping Michaels is a conventional 4 or 4 jump overcall of a weak 2 or 2. It promises a good two-suited hand with at least 5-5 shape. As an extension of the Michaels cuebid, it's named for the "leaping" or "jumping" aspect of the overcall.

• A 4 jump overcall shows clubs and the unbid major.
• A 4 jump overcall shows diamonds and the unbid major.

Additionally, Leaping Michaels can be used over minor-suit preempts:

• After an enemy 2, a 4 jump overcall shows clubs and an unspecified major.
• After an enemy 3, a 4 jump overcall shows diamonds and an unspecified major.

The 4 Jump Overcall

4 shows clubs and the unbid major after the opponents open 2 or 2.
