Defense Michaels

There is a conventional defense against the Michaels Cuebid. After an enemy cuebid that shows a two-suited hand, responder's conventional bids are:


Double: 

Natural with interest in penalizing the opponents in either of their suits.

Raising partner's suit :

A raise to the 3-level is a constructive raise (7-10 points) .
Shows 3-card support for a major, or 4-card support for a minor.
Non-forcing. A jump raise to the 4-level is weak and preemptive,
showing 4+ card support. Non-forcing.


Cuebidding theopponents' "known" suit:
If the opponents only promise one suit, e.g. a 2 cuebid to show
spades and a minor, then cuebidding their specific suit (spades) is
a limit raise or better. Forcing.


Cuebidding the opponents' "higher" suit:   

If the opponents show both suits, e.g. a 2 cuebid to show hearts
and spades, then a cuebid of the higher-ranking suit (spade) shows
10+ points and 5+ cards in the "fourth" suit. Forcing.


Cuebidding the opponents' "lower" suit:

If the opponents show both suits, e.g. a 2 cuebid to show hearts
and spades, then cuebidding the lower-ranking suit (heart) is
limit raise or better. Forcing.



Bidding the "fourth" suit:   

If the opponents show both suits, e.g. a 2 cuebid to show hearts and
spades, then bidding the "fourth" suit is natural, 7-10 points, with at
least a 5-card suit. Non-forcing.

Responder's priority is to show major-suit support, either via a direct raise or cuebid. Below are all the responses in greater detail.

The Double

Natural with interest in penalizing the opponents in either of their suits. Shows about 7+ points, and typically a balanced hand. Denies 3-card support if partner opened 1/. Note that this gives up the ability to play negative doubles in this situation.

  1. Michaels, showing hearts and an unknown minor.
  2. Natural, 5+ cards, 7-10 points, non-forcing. When the enemy's minor suit is unknown, then 3 and 3 are both natural, not cuebids.

Opener's Rebids

Opener's rebids are generally natural. However, a cuebid of either enemy suit typically asks for a stopper in that suit. Partner is asked to bid 3NT with a stopper.
