BR 14.1 - Simple Overcalls
When the Opponents open the bidding your side becomes the "defending side", and you should follow the principles of defensive bidding. You can make two types of bids : Overcalls and Takeout Doubles.
When the Opponents open the bidding it means that they hold probably at least 13+ points, and the chances of making a Game contract yourself have reduced considerably. Therefore the objectives of an Overcall, in order of their priorities, are :
- To give Partner a signal for a good opening lead
- To obstruct the Opponents' bidding
- To compete for a part score or, less likely, Game contract for your side.
Overcalls are usually made at the 1 or 2 level, but occasionally also at the 3 or even 4 level (up to 4♦), when an Opponent made a pre-emptive opening bid.
The requirements for making an Overcall are :
- at the 1 level : 8 - 15 points plus a quality 5+ card suit (value 7+)
- at the 2 level : 11 - 15 points plus a quality 5+ card suit (value 8+)
- at the 3-4 level : 12 - 15 points plus a quality 5+ card suit (value 9+)
The Suit Quality test
For an overcall the quality of the suit you bid is more important than the strength of the hand.
To determine the quality of your long suit : count the number of cards in your long suit and add to it the number of Honours you hold in that suit.
Length + Honours = Value
Count the Jack or 10 only if they are supported by a Queen or higher.
If the Quality value of your suit is equal to (or higher than) the number of tricks you bid, make the overcall. If it is less Pass. (Be especially vigilant about your suit's quality value when your side is vulnerable.)

BR 14.2 - Responses to Overcalls at the 1 or 2 level
An overcall is a limit bid, showing 15 HCPs or less (16 pts including length). As responder you may therefore pass at any time. With 8 points or less always pass, unless you have an unusual hand with a very long (6+ card) suit.
With 9-10 points or more you should find a suitable response.
In order of their priority
- Raise Partner's suit with 3+ card support
- Bid NT when balanced plus a stopper in the enemy suit
- Or, as last resort, bid your own 5+ card suit (hereby denying support for Partner's suit)
After Partner's overcall at the 1 level
- with 9 - 12 points - make a single raise of Partner's suit, or bid 1 NT
- with 13 - 15 points - make a jump raise of Partner's suit, or bid 2 NT
- with 9 - 15 points - and unable to raise Partner or bid NT, bid your own 5+ card suit
- with 16+ points - raise to Game in Partner's suit, bid 3 NT, or make a jump shift in your own 5+ card suit
After Partner's overcall at the 2 level
- with 13 - 14 points - invite to Game by bidding 3 in Partner's suit or bid 2 NT
- with 15+ points - raise to Game in Partner's suit, bid 3 NT, or make a jump shift in your own 5+ card suit
- with 10 - 15 points - and unable to raise Partner or bid NT bid your own good 5+ card suit
The original overcaller may pass with a weak hand when he sees no opportunity to a Game contract. Otherwise he may invite Game or go to Game himself.

BR 14.4 - Responses to Takeout Doubles
When your Partner makes a takeout double you may not leave him in that bid but must respond, even with no points at all. However if your right hand Opponents has made a bid over your Partner's double you may pass with 5 points or less.
Here are the standard responses after a Takeout Double.
Comment on the NT Responses
With a strong (13+ pts) hand yourself and no clear choice to bid you may cue bid the enemy suit (bidding the enemy suit at the next level). This signals to Partner that a Game contract should be on and asks him to specify his hand.

Hand 9
You hold Hand 9 below.
What is your response after the following bidding sequences (Opening Opponents' bids shown in brackets).
- (1♠) - DBL - (Pass) - You ? > > 2♥
Even with less than 6 points you should make a bid. Bid Hearts as your Partner either has 4 Hearts himself or is strong enough to make another call.
- (1♠) - DBL - (2♣) - You ? > > Pass
Your RH Opponent has bid, overtaking your Partner's double. With only 5 points you are too weak to make a proper response.

Hand 10

What is your response after the following bidding sequences (Opening Opponents' bids shown in brackets).
- (1♠) - DBL - (Pass) - You ? > > 3♥
With 13 points jumpbid your 4 card suit.
- (1♥) - DBL - (Pass) - You ? > > 2NT
With 13 points plus strength in the Opponent's suit bid 2NT. Partner's double shows he has the Spades covered.

BR 14.6 - The 1 NT Overcall
Overcalls of 1NT are the same as an ordinary 1NT opening bid (showing 16-18 points and a balanced hand), except for one thing. You must have a stopper in the enemy suit, preferrably two if they are holding a 5+card suit.
Hand 12
You hold Hand 12 below.
What is your response after the following bidding sequences (Opening Opponents' bids shown in brackets).
- (1♠) - You ? > > DBL
You have a strong hand, with 18 points, but no stopper in the enemy's Spade suit. A double is the perfect bid here
- (1♥) - You ? > > 1NT
Showing a strong (16-18 pts) hand with a stopper in the enemy suit.
The 1NT Overcall in 4th position
You are Not Vulnerable, your left hand Opponent has opened the bidding, your
Partner passed and your right hand Opponent responded with a suit bid at the 1
level.
For example : [1♣] - Pass (your
Partner) - [1♥] - you ?
You hold : ♠ - K 10 9
4 ♥ - Q J 9
♦ - A 9 3 ♣ - K 10
3
In this case, although you hold only 14 points, overcall with 1NT. This forces
Opponent to bid at the 2 level. If you let them bid and make 1NT they win 90
points. If on the other hand you play 1NT and go one down you lose only 50
points. If Opponents make an overtrick, scoring 120 points, you can go down 2, losing
only 100 points instead. These are much superior lines of action when playing
duplicate bridge.
When Not Vulnerable you can safely bid 1NT with as little as 10-15
points. When in 4th position with a strong hand of 16+ points, always
double instead.
When you are Vulnerable you should be very wary of such action, because going 1 down will cost your side 100 points.
And remember do this only in 4th position. In 2nd
or 3rd position, make the proper 1NT overcall (with 16-18 points).

BR 14.7 - Jump Overcalls
Traditionally jump opvercalls used to show a strong 17-18 points hand with a good 5+card suit. But in recent times these hands are expressed by a making a takeout double first, followed by a jumpbid at the next turn.
Jump overcalls are therefore free to express weak long 6+cards suited hands and follow the same bidding procedures and responses as pre-emptive (Lesson 13) and weak two opening bids (Lesson 16).
In general follow the Rule of 2 and 3
Hand 13
You hold Hand 13 below.
What is your response after the following bidding sequences (Opening Opponents' bids shown in brackets).
- (1♠) - You ? (vulnerable) > > 3♥
- (1♠) - You ? (not vulnerable) > > 4♥
All responses as per normal pre-emptive and weak 2 opening bids.
