This is a difficult topic in 2/1 Game Forcing (GF) because there are
different agreements (or no agreements by a partnership) and it is not clear
what is more usuful, so here we will propose an
approach that can be used by a partnership. Considerations: Different of SAYC in 2/1 we have the 1nt forcing after 1 /1
open, so Responder after bid 1nt may bid his long suit in his next bid. This was
a great improvement of 2/1 over the SAYC.On the other hand after 1
opening if Responder has 6+
and 8-9 hcp his bid in 1nt allows Opener to pass and then Responder may have
problems in hand's entry to make 5th and 6th good tricks in Clubs. One adapted solutions is not consider all responses in 2
having 12+ hcp as Two Over One determines as GF, so if Responder next bid
is 3
this shows 8-10 hcp with 6+
and it is a
non forcing
bid.Another approach possible is consider after 1
open the
response in
2 as normal GF
with 12+ hcp and the response of 3
showing long
Clubs
with 8-11 points (not hcp) where each card
additional after the fourth card is one point plus. Thus after 1
if Responder has xx xxxx KQ109xxx
that is: 5 hcp + 3 card points = 8 points - he has a valid response for 3.
Of course 3
should
have honors concentrated in Clubs, thus it is excluded possible
two top honors (A/K/Q) in others suit - just one is permited. After 1
opening follow the response in 3,
Opener must consider that a success in game
depends on Clubs support - sometimes fit is more important than hcp.
If Opener has:a) AQxx AKxx KQxx
x he
must pass - it is a misfit hand - b) KQ10 AJ10 J109x
Kxx he
should bid 3nt x) 8 Ax AKxxxx
A9xx he
should bid 6.Note1: After Opener bids 1
response in 2nt shows exactly 11 hcp with good middle cards
like 10/9 having distribution 3334 or 3325 with stoppers or semi-stopper (Q10x
or J10x) in the majors. So with two blank cards in a major it is not
recommended to bid 2nt. However with 3 blank cards in a major, even if
partner's hand has no stopper in this suit, the chances that suit is divided 4-4
is significant in
balanced distributions. If Responder has 4432 with both minors and 11 hcp he may bid 2
for inverted minors but having
strategic stoppers in the majors like:Kx KJ5 Q108x
K109x Responder should prefer 2nt.Thus, sometimes Responder must be creative to find the better response with 11 hcp: ============================================= RULE#1: After 1
opening the response of 2
shows 12+ hcp and denies support of 4+
cards but can have another 4 cards major suit if Clubs suit have 5+
cards as should be more frequent in 1
response 2.Opener Responder 1 2 <=
GF with 4+
and 12+ hcp - denies 4+RULE#2: After 1
opening the response of 3
shows 8-11 points (not hcp) with 6+
cards and denies other 4+ cards suit.Opener Responder 1 3
<= invitation with 6+
cards and 8-11 points ============================================= Now lets analyse the problem in Opener's second bid because Opener priority it is inform his strength to Responder and so we need here separate Opener's hand in 3 categories: 1- Opener has up to 15 hcp; 2- Opener has 16+ hcp; 3- Opener has undefined range but has a solid suit 6+ cards: AKQJ32 or AKQ5432 or AKJ65432 then bid 3

J543 GFOur propose to Opener second bid with minimum hand (1) is: - with balanced hand 12-14 hcp and stopper in both majors Opener should bid 2nt even having a 4 cards major - waiting to Responder's bidding his major in level 3 for then support Responder at level 4: K108 AJ10 KJ1086

xxxThus, after Opener rebids 2 ,
Responder having 4 cards major must bid his major suit to show 5+-4major
and that
not means any strong reverse just 12+

Opener Responder 1

2
<= 5+-4-x-x After Opener rebids 2 ,
Responder having 5332 or 4333 bids:a) 3nt with 12-15 hcp and stoppers in both majors denying possible interest in Slam - fast arrive principle; b) 2nt with 16+ and stoppers in both majors, waiting possible cuebid from Opener to try Slam: Opener Responder 1
2 <= GF 2 3nt <= 5332
or 4333 with 12-15 hcp
(fast arrive) Opener Responder 1 2
<= GF 2 2nt <= 5332

Responder with no stopper in one major rebids 3 waiting to know

and no stoppers in majors with Hxx
RULE#3- If Opener's second bid is a major in 2
or 2
this
is a reverse
bid showing 16-20 hcp and then Responder bids;- after 2
with 4
cards
bids 2
to show 45+;- 3nt with stopper in the other major and 12-14 hcp - fast arrive; - 2nt with stopper in the other major and 15+ hcp; - 3
denying stopper in the other major, showing 5+
cards andminimum hand 12-14 hcp without Hxx
probable Hx Hxx
;- 3
showing Hxx
and no interesting in nt - probable 6+
12-14 hcp;- support at level 3 to Opener major with 4 cards and 15+ hcp; - support at level 4 to Opener major with 4 cards and 12-14 hcp; - 4
shows solid Clubs suit 6+
cards in limited hand up to 15 hcp- jump to level 4 in the other major is a splinter showing 12-15 hcp. RULE#4- If Opener's second bid is 3
or 3
this
shows splinter
with 4+
cards support and up to 15 hcp - Responder bids are:a) 5
showing minimum and honors waste in the singleton;b) another suit - cuebid - try to Slam; c) 3nt showing 1,5 stopper in Opener's singleton; RULE#5- If Opener's second bid is 2nt this shows 12-14 hcp in 4333 or 5332 or 4432 with stoppers in both majors - Responder decides: a) 3nt conclusive; b) 3
shows Hxx in Diamonds and may be shorter in a major;c) 3
showing 5+-4
- then Opener decides;d) 3
showing 5+-4
- then Opener decides;e) 4
showing solid suit and interest in Slam - Opener must bid his first ace
control or sign-off in 5
even with singleton;f) 4nt asking for aces RULE#6- If Opener's second bid is 3nt this shows exactly 18-19 hcp in 4333 or 5332 with stopper in both majors and no major 4 cards - Responder decides: a) pass; b) 4nt asking for aces - rkc for Clubs; c) 5
or 6 or
6nt to
play.RULE#7- If Opener's raises to 3
this is a
normal 12-14 hcp,
but if Opener raises to
4 this
is a strong Clubs support like
5 cards
with with A or K or 4
cards with 2 top honors in a
hand with 15+ hcp where Opener is interested in Slam
and is asking
to Responder cuebid in sequence - Opener can have singleton/void in a major -
Responder decides:a) cuebid up the line: 4
with Hxx support (A or K) / 4
ace
/ 4
ace;b) 4nt asking aces b) 5
denies aces in others suits;RULE#8- If Opener opens 1
and Response bids 2,
Opener
jumping to 3 shows
a solid 6+
cards type: AKQxxxx
or AKQJxx and not a
strong hand, the importance of this bid is to show 6/7 tricks in .
Responder then decide:a) 3 /3
shows A or K in the suit bidded - interested in Slam;b) 3nt is to play showing stopper in both majors and 12-14 hcp; c) 4nt asking for aces - rkc for Clubs not for Diamonds; d) 5
to play - denies cuebid in majorsRULE#9- If Opener's second bid is 4
or 4
this shows a
distributional weak 6/5 hand up to 5 losers:8 AJ1093 KQ109xx
x
or AQJ84 Q10
AQJ97x
-Responder must consider that only aces are important for Slam at this level and with 3 cards in the major bidded he can pass or try Slam asking aces using RKC for the last suit bid. RULE#10- Finally, if Opener's second bid is 2
this is a weak undefined hand so it is a waiting bid to decide what to bid after
Responder's second bid. Responder bids are:a) 2
showing 5+-4b) 2
showing 5+-4c) 2nt showing stopper in both majors and 15-17 hcp; d) 3
asking for Opener bid his stopper in major - promise 1 stopper;e) 3
Hxx support in Diamonds - deny A or K stopper in major;f) 3
splinter - singleton Hearts - waiting for Opener to decide;g) 3
splinter - singleton Spades - waiting for Operner to decide;h) 3nt to play with stopper in both majors - 12-14 hcp; Note2: There are situations where playing 2/1 game force the bidding can stop at level 4 in a minor suit due to a misfit situations or without stopper in a specific major. |
