Competitive Bidding

When both sides are bidding your focus is no longer bidding game or slam. Most of the time you'll simply be deciding whether to defend against a contract by the opposition or try and play the hand yourself.

How high to bid in a competitive auction

If both sides are bidding then showing your points to partner isn't going to help much because, with the points spread around so much, you're less likely to have the strength for game anyway. In fact, bidding to a making contract is not your only consideration. You can sometimes get a better score by making a sacrifice bid, which means going down on your contract rather than letting the opposition make theirs.

Your trump fit will determine how high to bid in a competitive auction. The better your trump fit the more keen you should be to play the hand. Without a trump fit you'll probably be better off defending.


Simple overcall

Good 5 card suit, 10 - 15 points

An overcall is a bid made after the opposition have already opened the bidding. Just because the opposition have opened the bidding doesn't mean you can't bid. In fact, with the right hand, it's good to enter the auction. You might get to play the hand, you can take up some of the opposition's bidding space and you can suggest a lead to partner.

Unlike an opening bid, points don't matter so much for a simple overcall. A good 5-card suit is the key and good rule of thumb is two of the top four honours in the suit.

This next hand is not strong but spades would make a good trump suit, you take up opponents' bidding space and, if you end up defending, partner will know to lead a spade.

A good 5 card suit is all you need for an overcall

Responding to an Overcall

After an opening bid you will normally respond with 6+ points but you're not obliged to respond to an overcall in the same way. Sure, sometimes you'll want to explore for game and occasionally even slam possibilities but normally you'll simply be looking to compete for the partscore.

Here's the hand in the video for you to play yourself.

Competitive Bidding in Bridge

Change of suit

An opening bid of 1♣, 1, 1 or 1♠ doesn't promise a good suit. If you're playing 5 card majors, an opening bid of 1♣ or 1 might even be a three card suit. You'll be responding to an opening bid with 6+ points or even less in some cases in order to search for the best contract.

Partner's diamonds might not be very good and you might have a game on. Bid 1.

Unlike an opening bid, partner's overcall does show a good suit. There's often no need to search for a better contract because you're likely to already be in the best spot!

Pass after an overcall

Partner has 5 good diamonds. Pass!

Remember that an overcall won't be a strong hand so you're very unlikely to miss game by passing.

Raising partner's suit

If you do have a fit, it's good to support partner. 3-card support will be enough, because partner is showing a 5-card suit.

Responding to an overcall

Points don't matter - show your trump fit!

Weak jump overcall

Good 6 card suit, 6 - 10 points

A weak jump overcall is similar to a weak 2 opening bid. You can quickly describe your hand to your partner and at the same time make it hard for the opposition to enter the auction

Preemptive overcall

Good 7 card suit, 6 - 10 points

A preemptive overcall is similar to a preemptive opening bid.

Practice Hands


A double in bridge bidding can be either a takeout double, used to ask partner to bid, or a penalty double, used when a player thinks the opposition won't make their contract.

How can I tell whether a double is penalties or takeout? It can be hard to tell the difference! The state of the auction determines whether a double was meant for takeout or for penalties. Even expert players sometimes misinterpret the meaning of their partner's double. That's bridge! - but let's see if we can clarify things.

penalty or takeout double

Takeout Double

If the opener bids a suit and the overcaller doubles then it normally shows 12+ points and support for the unbid suits.

Takeout doubles in this situation are normally the first type that new players learn about. Doubles in other situations are often still 'for takeout' even though they are given different names.

Negative Double

Negative doubles, used by the responder, are another form of takeout double. A negative double is normally used when responder has a few points but is not strong enough to bid at the 2-level.

Balancing Double

A balancing doubles is simply a takeout double used when the auction is about to die out. It's often better to keep the bidding open at a low level rather than pass and defend against a part-score.

EW have stopped at the 2-level, so the points are probably evenly divided between the two partnerships. If South doesn't take some action, the auction will die, and your opponents will rest comfortably in their fit. South's seat is called the 'passout' seat.

What should South do? South cannot make a bid as that would promise a 5-card suit. South should make a balancing double. Consult partner who will not expect an opening hand as South has passed already.

If East or West bid 3, that will be a great result for NS. Don't spoil it by bidding 3♠ - you have already pushed EW too high!

Penalty Double

A double saying that you do not expect your opponents to make their contract is called a penalty double. It increases your score if the contract fails and also increases their score if the contract makes.

Doubles of notrump bids are almost always penalties. If your side has the majority of the points then doubling their 1NT contract can be more profitable than playing the hand in a contract your way.

How do I make a double when playing bridge on the computer

When you are playing bridge against the computer a double is shown as an 'X' in the bidding area.
