Lesson 6 -- After the 1Suit Opening and Response.
After the first round of the auction, then it is opener's turn to bid again,
and possibly responder will have to bid again. The first and foremost problem
is telling which bids are forcing and which aren't.
Which Bids are Forcing
Some bids are not forcing. These are any bid where responder has put an
upper limit on the number of points he has. The following bids by responder
are Not Forcing :
On the other hand, a suit change or a jump raise is forcing. The Jump
raise is forcing to game, and Any new suit by an unpassed responder
is 100% forcing for one round. (A passed responder has put an
upper limit of 12 HCP on his hand, and so may be passed if opener has an
absolute minimum, but they are still considered a semi-forcing bid).
- Any NT bid,
- Any Single Raise or double jump raise to game (4M/1M).
Opener's Rebid opposite a non-forcing bid
If responder has made a bid in NT, opener should be able to tell if there
is or isn't a game (presumably in NT). If opener has a balanced hand that
expects a game to make, bid 3NT. If you don't expect game to make, pass.
If you aren't sure (over a 1NT response) bid 2NT and ask partner if he is
at the top of the range or at the bottom.
If partner gave you a single raise, you are allowed to re-evaluate your hand
and add 3 for each void, 2 for each doubleton and 1 for each singleton (and
another point for each extra trump). If you have 16 or less HCP after that
evaluation, you should probably pass. If you have an invitational hand,
however, you should bid a good second suit. If you can count that you have
enough points for game (typically if you have 19-20), you should just bid
the game (4M or 3NT for minor suits, if you have everything stopped).
Opener's Rebid opposite a forcing response
If responder made a forcing bid, then your response depends on your hand
Opener has a weak hand
If you have a weak hand (13-16) points, you should:
The order is an approximate priority, unless partner's suit is a minor and
your suit is a major. Note that you may bid NT with an unbalanced hand, in
order to avoid raising the level by bidding a new suit.
- make a simple raise of partner's suit if you have support (enough to
bring the total to 8),
- rebid a 6 card or longer suit,
- bid a new 4+ card suit, if you don't go up a level, or
- Bid NT as cheaply as possible.
Opener has a strong hand
If you have 17-20 HCP, you should:
As above, the order is an approximate priority. You should not jump bid NT
with an unbalanced hand.
- Jump Raise your partner's suit if you have support,
- Double Jump Raise partner's 1M response to 4M if you have 20+ HCP
(after adding in distribution).
- Jump Rebid your suit,
- bid a new 4+ card suit cheaply, or jump bidding it if you have 19+ HCP.
If you jump bid your suit should be a very good 4 card suit or 5+,
- Jumping in NT with 19-20 (the 1 and 1/2 NT opening).
When you bid two suits, and your partner has to raise the level to get back
to your first suit, you have reversed. This shows 17+ HCP. Note that
if you open 1D and partner bids 1S and you bid 2H, that is a reverse, because
partner would have to go to the 3 level to support you. In a case like this,
you must hide your 4 card heart suit.
Bidding after a passed hand's semi-forcing response.
This is the same as above, but you may also pass with a fit and an absolute
minimum or with a poor fit and no good bid.
As above, the trick is to determine what bids are forcing. Unlike responder,
most of opener's bids aren't forcing. Forcing bids are:
If opener bids a new suit at the two-level, it is considered semi-forcing
if you bid a suit
at the one level (ie, forcing unless you have a bare 6-7 points)
and is usually played as forcing if you bid at the 2 level (in a new suit).
- Any jump bid of a new suit,
- Any new suit after the trump suit has been agreed
Here are some guidelines for responder's rebids and the following rounds
of an auction:
- If responder bid a new suit then jumped in opener's original suit (to
the 3 level), then he had a temporizing hand, 10-12 HCP with support.
- Each time you rebid a suit, you are showing an extra card in it (unless
you are rebidding it to go to game, or to decline an invitation to game).
- The more bids you had skipped to make a NT bid, the more likely your
NT bid is balanced. (1C-1D-1NT is almost assuredly balanced, whereas 1C-1S-1NT
may be an unbalanced hand, possibly hiding 4 hearts because bidding 2H would
be a reverse).
- If responder doesn't bid up the line in the majors (hearts then spades),
then responder has at least 5 spades.
- If either hand bids, then bids and rebids a new suit, that shows a
highly distributional hand (at least 5-5, maybe 6-5 or longer).
