If your partner has opened 1§ (the most common opening), his/her distribution
could be almost anything. It is very important to find out more about that distribution,
and in particular, to see if a fit in a major suit can be found.
The first requirement for a response is to have 6 DP or more for a response at the
1 level, and 10+ DP for a minimum response at the 2 level. Minimum point requirements are
even higher for bidding after an interfering bid.
Responses are classified as responses to with no
interference and with interference.

1¨ 
This is a forcing bid showing
(a) one or two
major suits exactly 4 cards long; and/or
(b) a diamond suit 5+ cards long 
With 54 in the majors, it is usually better to show the 5card major
suit first. However, with 10+ DP, you may bid 1¨ at first, to allow for bidding as follows:
1§
1¨
1NT 2ª 
1©/1ª 
This is a forcing bid showing a 5+ card major suit. You may
have 4 cards in the other major. 
With 55 or 66 in the majors, bid 1ª with 69 DP, and 1© with 10+
DP. With two unequal majors (65, 75, 76 or 85) bid the longer suit first. 
1NT 
Denies a 4card major suit or longer (4+), and promises 59 HCP.
Should have a balanced or semibalanced distribution. 

2§ 
This is a forcing bid showing at least 5 clubs, and no 4+ card
major. Promises 9+ HCP. Called an "inverted minor" single raise. 
An excellent way to decide between NT and minorsuit contracts. 
2¨/2©/2ª 
These are all forcing bids (essentially to game). They promise
nice 5+ card suits. Minimum points: 16 HCP. 

2NT 
Denies a 4card major suit or longer (4+), and promises 1011 HCP.
Should have a balanced or semibalanced distribution. 

3§ 
This is a preemptive bid, showing 5card support for clubs and no
more than 8 HCP. Lower point limit is determined by vulnerability. No 4+ card major suit.

A complementary bid to the 2§ "inverted minor" raise. 
3¨/3©/3ª 
This is a splinter bid, forcing to game in 5§ normally. The
suit bid shows a singleton or void, there should be nice 5card support for clubs and 13+
HCP. No 4+ card major. 

3NT 
The usual bid with 12+ HCP, no 4+ card major and welldistributed
points. 

4§ 
Forcing to 5§ at least. Good 5+ card club support, no 4+ card
major, 16+ SP and at least 3 MCCs. 
A strong slam try. 
4¨/4©/4ª 
These are essentially preemptive bids with a 7+ card suit and 10+
HCP. 
With any perceived chance of 3NT (rather than 4¨, 5§ or slam), other
bids should be made. 
4NT 
Blackwood. Very strong try for 6§ or 6NT. 
All you care about is how many Aces opener has. 
5§ 
You have the long suit and the points to play a game contract, but no
more than 2 MCC.

8+ DP and a 5+ card diamond suit. No 4card major. Forcing. 
You may lie a bit with a nice 5card suit, and bid it
with 56 DP.

have 8+ DP. 
You may lie a bit with a nice 5card suit, and bid it
with 56 DP.

have 8+ DP.

Double 
This takes the place of the 1¨ forcing
response (and equivalent to the "negative double"). Should have 4 cards in the unbid major, and 8+
DP. If RHO bids 1ª, a double can even mean 5 hearts and 89 HCP (as you should not go to
the 2 level with <10 points). 

1NT/2NT/3NT 
89/1011/12+ HCP but with some control of opponent's
suit. No 4 cards in the unbid major. 

Cuebid (i.e. 2© over 1©) 
Shows a very strong hand (13+ SP) with 5+ club support
and good control of opponent's suit. Forcing. 

Most other bids (but what do 4 and 5 in the opponent's
suit mean?) 
Same as above, but should
have 8+ DP.

Double 
This takes the place of the 1¨ forcing
response. Should

2¨/2©/2ª 
5card suit with 10+ DP 

3¨/3©/3ª 
5card suit with 16+ HCP 
Now, let me see. Your partner promises 13+ HCP, you have 16+
and so does the RHO. Someone is lying! 
All other bids 
Same as above 

Other interference bids
