| Other agreements concerning
doubles and redoubles: |
| Doubles are for take-out unless: we have a fit; we have
pre-empted; we are doubling a naturally-bid NT. |
| After
penalty double of 1NT, next double by either player is
take-out. |
|
If
opponents bid the UNT, cue-bidding their lower suit shows
support for partner's opening, cue-bidding their higher suit
shows 5+ in the fourth suit. |

OTHER CONVENTIONS |
|
Fourth-suit
forcing [1♠
is natural] |
|
After 1X-2Y, 2NT is game-forcing
[3♣

flat 15/16 |
|
Unassuming cue-bids (show good raise of
partner's suit or very strong hand) |
|
Directional asking bids |
|
1NT rebid is 15-17 [2♣

SUPPLEMENTARY
DETAILS [1] |
| (Please
cross-reference where appropriate to the relevant part
of the card and continue on back if needed) |
|
1.1 |
Splinter jump shows support
for partner [min 4] with typically singleton in bid suit.
A splinter bid can be an immediate response, opener's
rebid, or an unnecessary [to be forcing] bid at any
stage of the auction. |
|
1.2 |
Jacoby 2NT promises 4+ trump
support and is forcing to game. Opener rebids 4-major if
minimum. 3-new-suit as trial bid, 4-new-suit as
splinter. |
|
1.3 |
Minor-suit
cue-bid shows at least 5-5 in the majors. Major-suit
cue-bid shows at least 5-5 in other major + unspecified
minor. Usually weak/strong, not intermediate [i.e. not
in range 11-15] |
|
1.4 |
|
|
1.5 |
2♣=both
majors, 2♦=4-card
major plus longer minor, 2-major=minimum 5-card suit |
|
1.6 |
If partner
doubles a weak 2-bid, 2NT shows a weak hand [<8] and
requests a 3♣
relay. |
