Bids
available for inviting game: 2 NT, 3 of a previously bid suit:
1H --1S
2D -- 2NT, 3D, 3H, 3S = 11-12 points,
inviting game.
Second-round
forcing bids. A new suit response (other than
after 1NT rebid by opener)
is a one-round force. If it is a fourth suit in the
auction, it may be artificial.
1H -- 1S
2C -- 2D = one round force, could be
artificial.
.....but....
1H -- 1S
1NT -- 2C, 2D = non-forcing. Responder must jump shift to 3C or 3D to force
game.
Second
round forcing bids following a 1NT rebid by opener: A reverse or jump shift into a new
suit is a game force.
6.1
1C -- 1H
1NT -- 2S or 3D = game force.
Bids
available for signing off in game.
3NT, 4H, 4S, 5C, 5D.
IF
responder initially bids a new suit at the two level, the same rules apply EXCEPT that a
subsequent jump raise of opener's first suit to the THREE LEVEL is game forcing (responder
should make a limit raise directly over the opening with 10-12 points and at least
three-card support):
6.2
1S -- 2C
2H -- 2NT, 3C, 3H = invitional to game
(11-12 points).
-- 2S =
Preference, not forcing. Responder has 11-12 points and a doubleton spade.
-- 3D =
Game force, could be artificial.
-- 3S =
Game force.
NOTE:
Responder promises to bid again if he responded with a new suit at the two level unless
opener's rebid as at the game level.
1S -- 2C
2D = forcing one round. Responder can
limit his hand by bidding 2S, 2NT, 3C, or 3D
at this point. He should not pass, since opener could have 18
points (just short of a jump
shift rebid).
