NO TRUMPS FORCING (AND INVERTED AFTER
1 OPEN)
Playing
SAYC (Standard American Yellow Card) after the Opener bid a major suit in
level 1 the Responder with 6-9 hcp
(high cards points A=4, K=3, Q=2. J=1)
and a long minor suit 6/7
cards
without support
of 3 cards to Opener suit must bid 1nt and then Opener can pass.
Opener Responder
1 1nt Opener:
 K9x AQ9xx  xx  KJx
pass Responder:
xxx xx KQJ10xx xx
Of course, opponents lead in a black suit and they hold
A
until the communication is break, so all good diamonds aren't used and contract goes
down.
In evolution of the system, when your partner opens in a major suit, playing "2 over 1
game forcing", it is
now part of
the system that response of 1nt after a major open makes the
auction one round force and then the Responder can also bid his
long suit as a sign-off.
1NT FORCING
Opener
Responder or
Opener Responder
1
1NT <=
forcing
1 1NT
<= forcing
and the range of 1NT change from 6-9 to 5-11 hcp
However,
after partner has opened 1, many partnerships adopt an inverted response bidding for 1 and 1NT,
because this makes an improvement in the bidding like did the old Flannery 2
system 50 years ago, for hand’s open having 4522.
Without the inverted response, minimum hands (12-15 hcp) in 4=5=2=2
distribution like:
KJxx Q9xxx Ax Kx or AQxx J87xx
Ax Qx
have no suitable bid after 1NT forcing because Opener would have to bid two Clubs with only 2 cards
or rebid his
suit with only
5 cards.
Examples of 1nt inverted and forcing are:

SO NOW LETS ANALYZE THE BIDS AND RESPONSES IN
NT FORCING AFTER 1/1 OPEN USING INVERTED NT
After 1 from responder, the opener of 1 bids:
A) 1NT showing 4 cards in (hand type 4=5-x-x) and minimum (12-15
hcp). If
responder has 4 cards in he bids 2 with 5-9 hcp and 3 with 10-11 hcp, 4 with 12-15 hcp, and
others forcing bids like splinters, RKC ...
Opener..... => KJxx Q9xxx Ax  Kx
Responder => A9xx 10x Jxx Qxxx
Opener Responder
1 1 => denies 5+ and can have 0-4 cards - must be alerted
1NT 2 =>
sign-off and
must be alerted because it shows 4 cards in .
Opener..... => KQxx QJ9xx AJx Q
Responder => A9xx 10x Kxx Kxxx
Opener Responder
1 1 => denies 5+and can have 0-4 cards - must be alerted
1NT 3 =>

************************************************************
After 1 from responder, the opener of 1 bids:
B) a minor suit at level 2 to show his second suit (can be 3 cards in 5332)
Opener Responder

?
Opener: A9 KJ10xx Qxx Kxx => bid 2 with 3 cards
Opener: Kxx K9xxx AJx Kx => bid 2 with 3 cards
***********************************************************
After 1 from responder, the opener of 1 bids:
C) 2 with 6+ cards and 12-15 hcp
maybe with unremarkable spades like 8xxx AKJ1087 Ax x
better to say 2 than 1NT after 1 from partner.
Opener Responder
1

2 <= shows 6 (or 7) cards
Opener: A9 KJ109xx QJx Kx
Opener: A9x AQ10xxx Qxx x
***********************************************************
After 1 from responder, the opener of 1 bids:
D) 2 to show strong hand 16-17 HCP in hands type 4=5=x=x. If partner then bids a minor suit,
opener can pass with singleton, but with 3 cards opener can try game making an
invitation or bidding directly 5 in his suit depending on our first controls
(Aces) in majors and the strength of opener's hand.

here responder with 13+ hcp should try Slam
Opener Responder
1
1nt <= 5-11 hcp
3nt <= 5332 with 18-19 hcp
After 1 from responder, the opener of 1 Bids:
E) 2NT to show strong hand 18-20 HCP GF, having 4 cards in other
suit (hand type 5-4-x-x) or having 6 cards. This bid will distinguish a 5-5 distribution from
a 5-4 distribution avoiding a jump in the second suit with only 4 cards.
So after 2NT GF the responder alert his 3 bid asking for explanation of the
suit and distribution:
Opener Responder
1
1 <= deny 5 cards
2nt FG 3 <= asking for
hand distribution FG
?
3 =>

3NT =>

4 => 7 cards (AKQxxxx / AKJ10xxx / KQJ1098x) - need alert
If responder bids a different suit, without asking 3, this is sign-off, so if he bids your singleton or
doubleton you should pass, but if was your tripleton (or 4 cards in a
tri-color hand) you can think in game and depending on yours first controls in
the majors and honor in support of your partner, you make a
invitation or directly bid game or maybe a small slam!

Note: It is important to assume that always another suit from responder is
not forcing but just a invitation for game only in his suit.
Fit is mostly important than hcp!
(if a misfit is found drop the bidding as soon
as possible – Terence Reese)
************************************************************
After 1 from responder, the opener of 1 bids:
F) Jump in another suit is 5-5-x-x with 18-20 hcp. The exception occurs in
the rarely hands like 6-5-x-x where the 15-17 hcp are all concentrated in the
2 suits making strong suits with less than 4 losers, because with less than 21
hcp you can't open in
2 even with 2
presumable losers!
Experience shows us numerous disasters when the opener of 2 Clubs having two
long suits, after a big preemptive bid from opponent, must make his second declaration at level 5 and his partner passes
in his singleton having 4 cards in the other unbidden
suit.

*************************************************************
After 1 from responder, the opener of 1 bids:
G) Jump in the same suit (denying closed suit) is always a problem because
some partnerships prefer to use the jump just in invitation cases, with 6
cards and 16-17 hcp (used more), and others use it in game forcing to show
18-20 hcp. Both ask for 2 cards support from partner, but the first case
(invitation) needs also 8 hcp or more to continue.
In both cases another suit
from responder shows weak hand with 6 or 7 cards, so with singleton the
Opener can pass even with maximum hand.

*************************************************************
Note: In hands with 16-17 hcp, opener
after limited response bid of 5-11 hcp must bid like having 12-15 hcp in first round and bid again if he
has chance:
Opener Responder
1
1
<= 5-11 hcp
?
2/2 => 12-17 hcp waiting for
Responder's 2o. bid to pass or bid again
Opener Responder
1
1nt => 5-11 hcp
?
2/2/2
=> 12-17 hcp waiting for Responder's 2o. bid to pass or bid
again
It is prudent assuming always partner with minimum range, hand 5-7 hcp in principle.
So, he needs to bid like having 12-15 hcp and not 16-17 hcp, because a jump is
reserved only for a strong hand with 18-20 hcp.
Partner could have a middle range hcp (8-9) or a maximum range hcp (10-11)
hand. If your partner has a maximum range (10-11 hcp) after your bid, he must
bid again:
- normally 2NT or
- jumping to his long suit or
- jump to your open suit
to show 3 cards support or
- making a simple raise invitation in your second
suit.
In all these cases you can go to game without problem.

When you have a 5332
hand with 15-17 hcp and 5 cards majors the first recommendation is open in
the major because you play Stayman and that not allow you to find a 5-3 fit,
but there are exceptions where the open in 1nt with 5 cards majors is
acceptable as the best approach if you need protect some honors like Kx or
AQ, so with weak major suit and good stoppers in all others suits like
AQ10 108765 A109 AQ this
avoid your partner bid nt!
