VS.
Defense After Unusual Notrump (Basic System is ,, & )

Modifications and Extensions presented by Mike Savage
After 1-of-a-suit and a 2 NT overcall, you always
know which two suits the 2NT bidder holds.
Basic defensive strategy over our major suit opening/2NT is to
cue-bid the lower of their suits to show the unbid
major and bid the higher of their suits to show good support for partners
suit; both bids showing invitational or better values. Three of
partners suit is a competitive raise and double will be penalty oriented but
may also be a balanced hand, invitational or better with 3-card trump support.
If partner opens 1-of-a-minor,
followed by 2 NT showing both minors (rarely), then 3C is a transfer to
hearts, 3D is a transfer to spades, both invitational or
better & 3H/3S are weak, showing a
good suit.
1. After 1 of a Major 2 NT - for
both minors:
Double = Shows defense and inviting partner to double or pass with
defense.
Rebids by Doubler (example: 1H 2NT
DBL 3C:
Dbl = Penalty
3 of Openers
Major = Invitational, three trumps & good defense.
3 of Unbid
Major = 4-card suit, forcing with strength in unbid
suit.
3NT = To
play with good defensive values.
4C/4D =
Slam interest cue-bids with a fit and a balanced hand.
3
Clubs = Shows five or
more cards in the other major & is invitational
or better.
Response: 3D = Denies 3-card
support or a 6-card major suit.
3 Diamonds = Shows an invitational or better raise in openers
major.
3 of Openers Major = A competitive raise, about
6-8/9 points and four trumps.
3 of Unbid Major = Shows a very good
6-card suit with nothing else outside.
3NT = 4
cards in the other major, 3 of partners major and game values or better.
4
Clubs/4 Diamonds = Splinter raises; at least four trumps and game
values.
2. After 1
of a Minor 2 NT - for hearts and the other minor (2
lowest unbid suits):
Double = Showing defense and inviting partner to double or pass
with defense.
