HOW RESPONDER COMPETE
After an opening in first or second position if opponent interfere
there some standards bids in 2/1 system where Responder may inform his
hand to Opener and here we will discuss some of these Responder’s bids:
PART 1/3 – RESPONDER HAVING LESS THAN 10 HCP
1- Suppose Responder has:
♠xx
♥xx
♦AQJ10xx
♣J10x
and bidding goes:
a) Opener Overcaller Responder
1♥
1♠
3♦
<= less than 10 hcp and good 6♦
cards
b) Opener Overcaller Responder
1♥
2♣
3♦
<= less than 10 hcp and good 6♦
cards
c) Opener Overcaller Responder
1♥
double 2♣
<= no redouble, less than 10 hcp, transfer to 2♦
the transfer allow the more strong hand receive the lead and Responder
may also inform his partner that he has support!
d) Opener Overcaller Responder
1♠
double 2♣
<= no redouble, less than 10 hcp, transfer to 2♦
e) Opener Overcaller Responder
1♥
2♠
double <= 4♦+4♣+
or 7-9 hcp and long minor suit
after partner opening and a overcall occurs the double is to inform
Opener that Responder has the other two suits and this do not define the
Responder strength but shows not a hand up to 10 hcp. But if Responder
bids again he is bidding a long suit and his hand is weak.

2- Suppose Responder has:
♠xx
♥AQJ10xx
♦x
♣J10x
and bidding goes:
g) Opener Opponent Responder Overcaller
1♠
pass 1NT 2♦
pass pass 3♥
<= invitation to 4♥
shows 6/7 cards and 9/11 hcp
Why Responder didn’t bid 2♥?
Because in 2/1, 2♥
after 1♠
opening need 12+ hcp
h) Opener Overcaller Responder Opponent
1♠
2♣/2♦
double* 3♣/3♦
<= support
pass pass 3♥
<= sign-off * means less than 10 hcp
i) Opener Overcaller Responder Opponent
1♠
2♣/2♦
double pass
pass pass 3♥
<= invitation to 4♥
(if 2♥
then sign-off)
---------------------------------------------------------------------------------
3- Suppose Responder has:
♠xx
♥KQJxxx
♦x
♣J10xx
and bidding goes:
j) Opener Opponent Responder Overcaller
1♠
pass 1NT 2♦
pass pass 2♥
<= sign-off
k) Opener Opponent Responder Overcaller
1♠
pass 1NT 3♦
pass pass 3♥
<= sign-off
==============================================
PART 2/3 – RESPONDER HAVING 10-11 HCP
When Responder has support to Opener's major after the interference the
priority is inform partner about invitation hand with 10-11 hcp. Not
necessarily bid another suit and after support partner because this may
confuse Opener: may seems slam interest or 2 cards support? So cuebid is
the appropriate way to inform the invitation.
4) Suppose Responder has:
♠10xx
♥AQJ10x
♦xx
♣K10x
and bidding goes:
l) Opener Overcaller Responder
1♠
2♦
3♦
<= 3♠
cards support 10-11 hcp
?
3♠
<= minimum opening 12-13 hcp - Responder should pass
3NT <= strong opening 18-19 hcp - Responder may pass
4♣
<= asking for cuebid - Responder may cuebid 4♥
4♠
<= good opening 14+ hcp - Responder must pass
m) Opener Overcaller Responder
1♦
1♠
2♥+
and 10+ hcp one-round force
?
2NT pass pass
3♣
pass pass <= without support game is difficult
3♦
pass pass <= maybe a misfit hand
3♥
pass pass <= Opener has minimum hand
3♠
pass 4♣
<= Opener splinter shows slam interesting
4♥
pass pass <= Opener has good hand
n) Opener Overcaller Responder
1♣
2♠
3♥
or double <= difficult decision but double followed
? by 4♥
is a good bid to avoid overbid
2NT pass pass
3♣
pass pass
3♦
pass 3♥
3♥
pass 4♥
4♥
pass pass
===============================================
PART 3/3 – RESPONDER HAVING 12+ HCP
When partner opens and opponent interfere making Responder's bid be at
level 2 or 3 if Responder double this shows 8-11 hcp but if Responder
bids then this must be GF with 12+ hcp. In case Responder double to show
4 cards in the other major and after cuebid this is GF.
5) Suppose Responder has:
♠10x
♥AKJ10x
♦xx
♣KQ10x
and bidding goes:
o) Opener Overcaller Responder
1♠
3♦
3♥+
denies 3♠
cards
?
3♠
=> 4♠
3NT => pass
4♣
=> 5♣
4♦
=> 4♥
4♥
=> pass
p) Opener Overcaller Responder Advancer
1♣
1♠
2♥
3♠
pass pass 4♣
<= not GF because there are 2 Spades losers
?
pass <= also 2 Spades losers
4♥
<=
♥Qx
or xxx with minimum
5♣
<= singleton Spades with minimum 5♣+
cards and
♦
control
6) Suppose Responder has:
♠x
♥AKJx
♦Kxx
♣KQ10xx
and bidding goes:
After partner opening in a minor if Overcall is in Spades a double by
Responder promises 4♥
cards and may have 5♥
or 6♥
if Responder bids Hearts at level 3 as a sign-off bid.
q) Opener Overcaller Responder Advancer
1♣
2♠ double
3♠
pass pass 4♠
<= GF singleton Spades or Ace/void
?
4NT <= need 2 aces to try Slam
5♣
<= only one ace
r) Opener Overcaller Responder Advancer
1♣
1♠ double
2♠
3♥
pass 3♠
<= GF singleton Spades or Ace/void
?
4♣
<= need 2 Aces to cuebid so Responder should bid 4NT
and using RKC1430 if Opener response is 5♠
then 6♥
and if response is 5♥
(no Q♥)
then pass
4♥
<= only one ace minimum so Responder should pass
