3.1
If,
after the transfer is accepted, responder bids a new suit that is natural and game
forcing. Possible calls after the accepted
transfer are:
1NT
-- 2H
2S
-- Pass = content to play 2S
--
2NT, 3S = invitational. Over 2NT opener can pass or return to 3S with a
minimum
hand;
bid 3NT or 4S with a maximum.
--3C,
3D, 3H = natural and game forcing.
--3NT
= asking for a choice between 3NT AND 4S.
--4S = placing the contract, with a six-card or longer
suit.
3.2
A
2S response requires the 1NT bidder to rebid 3C, which can be passed with a club bust, or
responder can rebid 3D with a diamond bust. Example:
1NT -- 2S
3C -- Pass = Bust
--
3D = diamond bust (notrump opener
passes).
3.3
Other
responses to 1NT:
1NT -- 3C, 3D = invitational to 3NT
with a six-card or longer suit.
-- 3H, 3S = At least a six-card suit
and slam interest (otherwise responder uses at transfer bid.
-- 4C = Gerber, asking for aces. 4C IS
GERBER OVER ANY 1NT OR 2NT BID B
PARTNER, INCLUDING A REBID OF 1NT or 2NT. Responses show the
number of aces, by steps, just as over a Blackwood 4NT. (5C is used
asking for kings).
Ace Asking
King Asking
1NT --4C
1NT -- 4C
4D = 0 or 4 aces
4x -- 5C
4H = 1 ace
5D = 0 or 4 kings
4S = 2
aces
5H = 1 king
4NT
= 3 aces
5S =
2 kings
5NT = 3 kings
If
the player using Gerber makes any bid other than 5C, than is to play (including 4NT).
A
direct raise of 1NT to 4NT is natural and invites 6NT.
4NT is slam invitational only because 4C is available as Gerber.
