Weak Twos: Make Life Difficult for the Opponents

Weak twos are one of bridge’s most useful weapons.

You don’t expect to make lots of contracts after opening a weak two. That isn’t really the point. The aim is to describe your hand quickly while taking away valuable bidding space from the opponents.

And, every now and then, partner has exactly the right cards and your apparently modest hand turns into game.

What is a weak two?

A weak two is an opening bid at the two-level showing a good six-card suit and a hand that is too weak for a normal one-level opening.

In a typical Acol-style system:

• 2♥ shows a weak hand with six hearts

• 2♠ shows a weak hand with six spades

• 2♦ may also be weak in some systems, although Benji Acol players normally use 2♦ for a strong hand

The exact strength is a partnership agreement. Something around 5–9 HCP or 6–10 HCP is common.

The important word, though, is not points. It is suit.

A weak two should normally have a suit you are quite happy to advertise.

Compare:

♠ KQJ986 ♥ 84 ♦ 73 ♣ 952

with:

♠ J76432 ♥ KQ ♦ A5 ♣ 874

Both hands have similar high-card strength.

The first is an attractive 2♠ opening. The second is much less appealing. Its points are outside the long suit and the spades are poor.

Why open at the two-level?

Imagine the opponents have 25 points between them and would like to have a nice, leisurely auction:

1♣ – 1♥ – 2NT – 3NT.

Very civilised.

Now imagine you open 2♠ before they get started.

Suddenly they have to begin at the three-level. They may struggle to find their heart fit, judge whether they have enough for game, or work out whether 3NT is safe.

You have made their life harder before they have even made a bid.

That is the real value of pre-emption.

Vulnerability matters

Weak twos should not be completely reckless.

At favourable vulnerability, when you are not vulnerable and the opponents are, you can afford to be more adventurous.

At unfavourable vulnerability, you should be more disciplined.

Why?

Because going three down doubled when not vulnerable costs 500. If the opponents can make a vulnerable game worth 600 or more, that may be an excellent result.

Three down doubled when vulnerable costs 800.

Less amusing.

So when vulnerable, particularly against non-vulnerable opponents, look for a better suit and a more respectable hand.

Position matters too

A weak two in first seat is very different from one in third seat.

In first seat, partner has not yet had an opportunity to bid. If you pre-empt aggressively, you may make life just as difficult for partner as you do for the opponents.

In third seat, partner has already passed.

That gives you rather more freedom.

Third-seat weak twos can therefore be lighter and more obstructive, particularly at favourable vulnerability.

Don't pre-empt with a hand that wants to bid again

A useful test is:

If partner asks me to stop bidding, am I happy to stop?

Suppose you hold:

♠ AQJ1086 ♥ K7 ♦ A4 ♣ 963

This may have six spades, but it is far too strong for a weak 2♠.

Opening 2♠ risks losing game because partner will assume you have a much weaker hand.

Weak two openings work because they give partner a reasonably accurate picture immediately.

If you routinely open them with hands ranging from 4 to 14 points, partner has no idea what to do.

What should partner do?

One of the most common mistakes after a weak two is bidding simply because partner has opened.

Remember: partner has already described the hand.

If you have no particular reason to bid, Pass is perfectly respectable.

For example:

Partner opens 2♠ and you hold:

♠ 73 ♥ KJ84 ♦ Q105 ♣ K872

You do not need to rescue partner.

You do not need to show your hearts.

You certainly do not need to bid 2NT just because you have 9 points.

Pass.

Partner promised six spades. Let them play there.

Raising can be wonderfully annoying

Suppose partner opens 2♠ and you hold:

♠ 9742 ♥ K86 ♦ 83 ♣ QJ73

You haven't suddenly discovered a game-going hand.

But you do have four-card spade support.

A raise to 3♠ may make the opponents' auction considerably harder.

This is an important principle of pre-emptive bidding:

With a fit, you often bid higher because you have more trumps, not because you have more points.

That is why the Law of Total Tricks is often useful in competitive auctions.

Don't confuse "making" with "correct"

You open 2♥, partner raises to 4♥ and you make eleven tricks.

Excellent.

That does not necessarily mean you should have opened 1♥.

Likewise, if you open 2♠ and go two down, that does not automatically mean the opening was wrong.

Pre-empts need to be judged on the information available when you bid, not on what happened after all 52 cards became visible.

Sometimes a perfectly sensible weak two goes down.

Sometimes a dreadful weak two makes game.

Bridge can be unhelpful like that.

The biggest weak-two mistake

Perhaps the most common error is simply having too many rules.

Players worry:

“Can I have an outside ace?”

“Can I have a four-card major?”

“Must I have exactly 7 points?”

“Can I open this vulnerable?”

Those are useful partnership discussions, but the central idea is much simpler.

Ask yourself:

Do I have a good six-card suit, a genuinely weak hand, and would opening at the two-level make the opponents' auction more difficult?

If the answer is yes, you probably have a weak two.

Bridge Coach takeaway

When considering a weak two, think:

Suit first. Points second. Vulnerability third.

A good weak two describes your hand, helps partner and steals bidding space from the opponents.

And if they look slightly uncomfortable when you put the 2♠ card on the table, it is probably doing its job.
