The Finesse in Bridge

Finessing is a way of making a trick with an honour card that would be a certain loser if it was led.

Suppose you are playing as South and you have the following cards in the suit you want to finesse.

Is it possible to win a trick with the King?

If the King is led it will always lose regardless of which opponent holds it. Remember, bridge is played clockwise, so both East and West will play after North - and play the ace on the king if the hold it.

Can you prevent this from happening?

What will happen if instead of leading the King you return to the South hand and lead a low card? Can the Kind win now?

You have a 50-50 chance that the King could win. If the King is in West's hand you can make a trick with it.  If it is in East's hand then the King will lose. 

An Example of Finessing

Here's that hand again

This time you are going to lead a low card from hand and see what card West plays:

  • If W plays the Ace, you can play the low card from dummy, knowing that the King will win next time the suit is played.  
  • If W doesn't play the Ace you play K. If W also holds the Ace, then your King will win the trick.   If the Ace is with East then there is nothing you can do, as E will play the Ace after you have played King.
Finessing Summed Up
Lead a low card towards the honour you are aiming to make.  50% of the time this will win. 

Leading the honour card will always fail.

You can increase your chances of making the finesse by studying the bidding and the play.  If, for example, East opened the bidding and West passed, then you know that W didn't have enough points to respond to East's opening bid.  How many points has W shown before you start finessing?  Would holding the Ace mean that W actually had enough points to respond?  If this is the case, then West's failure to respond to the opening bid would place the Ace with East and your finesse will fail.

Marked Finesse

Unlike a regular finesse, which may fail, a marked finesse is guaranteed to win.

What is a marked finesse?

With a marked finesse we know which opponent has the remaining card(s). 

How can we know?  Because one opponent has already discarded and so is out of cards in the suit.

An Example

Suppose you have the following cards in the suit you are finessing:

Is it possible to make all 4 tricks?  (We are assuming trumps have been drawn or this is a NT contract so that the opponent who has shown out can't trump you.)

If the cards break 3-2 between East and West, you will make 4 tricks and no finessing will be needed.  The same is true if the cards break 4-1 with one opponent holding the Jack as a singleton.

But the singleton might not be the Jack, or the cards might be breaking 5-0.  Now what should you do?

This is the Marked Finesse is used

As an example, supposed you've played one round of the suit, in which W played 9.  You decide to play a second round, but this time W discards.  This means that the outstanding J and 7 must be with West.

Using the Marked Finesse

Just as with a regular finesse you lead low towards the honour you are hoping to make. 

Look at the cards.  You have already played 2 rounds of the suit, so the King and Ace have gone.  If you now lead the Q, East will play the 7, keeping the J to win if the suit is played again.

However, if you cross over to dummy (you did make sure you'd preserved an entry to dummy so you could play the finesse, didn't you???), then you can lead a low card, knowing that East has the J and 7.

Once you've led your low card, one of two things will happen:
  • East plays 7.  You can win with 8, knowing your Q will win next time.  Y
  • East plays J.  You win with the Q and your 8 will win the next round.  y
Now that you know what finessing means, you can head over to No Fear Bridge where you will find lots of hands where you can practice the technique along with tutorials to help reinforce what you've learnt.

Gerber Bidding Convention

The Gerber Bidding Convention

Most bridge players know about using the Blackwood bidding convention if you are considering bidding for a slam. 

Once you know you have enough points to bid for a slam bid and have decided which suit you will bid, you might need to know how many aces or kings partner has.  To do this you bid 4NT to ask partner how many aces they hold and 5NT to ask how many kings.

This works because 4NT isn't a natural bid UNLESS it is in response to an opening bid of 1NT or 2NT, in which case it is in invitational bid with a special meaning.  It tells partner that you have a narrow range of points that would achieve the points needed for a slam IF they have the maximum number of points for their NT bid - and asking them to bid 6NT if they do.

But suppose you need to know the number of aces or kings held by partner after their opening NT bid?  You can't bid 4NT as they will assume your bid is invitational and bid on points.

This is where you use the Gerber convention.

In response to an opening bid of 1 or 2NT  you use a bid of 4 Clubs to ask for Aces and 5 Clubs to ask for kings.

Partner's responses are the same as those used in for Blackwood.

In response to 4 Clubs:

  • 4 Diamonds = No aces or four aces
  • 4 Hearts = One ace
  • 4 Spades = Two aces
  • 4 NT = Three aces
In response to 5 Clubs:

  • 5 Diamonds = No aces or four aces
  • 5 Hearts = One ace
  • 5 Spades = Two aces
  • 5 NT = Three aces

Improve Your Health - Play Bridge

Yes, it's true, there really are benefits to your health if you are a bridge player. It's even been the subject of research by Berkeley University.

There has been a long running debate about whether or not bridge counts as a sport and in June 2017 it seemed that the European Courts of Justice might rule that it is.  This wasn't to be as in Oct 2017 the Court ruled that although bridge "involves logic, memory and planning, and may constitute an activity beneficial to the mental and physical health of regular participants”, they clarified this by adding "“The court concludes that an activity such as duplicate bridge, which is characterised by a physical element that appears to be negligible, is not covered by the concept of ‘sport’”"

You can read more in the Guardian newspaper HERE.

Although the European Court has denied that bridge is a sport they have acknowledged that it has benefits to both mental and physical health - something that many bridge players will long have realised.

I mentioned above that bridge had been the subject of a study by Berkeley University. This study was carried out in 2000 by Professor Marian Diamond who showed that playing bridge boosts the immune system. 

How can playing bridge boost your immune system?  It seems that this is an effect of the concentration required whilst playing which stimulates the brain and so boosts the immune system.

Professor Diamond asked 12 ladies in their 70s and 80s to take part in the study. He started by taking blood samples and then asked the ladies to play bridge for an hour and a half.  At the end of this time he retested their blood.

Two thirds of these ladies showed an increase in the levels of T cells in their bodies - the cells used to fight infection.

There is a common saying "use it or lose it".  As we get older this saying applies very much to keeping the brain active and healthy.  People live longer and want their brains to remain active and alert.  Playing bridge is the perfect way of keeping your brain active and maintaining your ability to concentrate and focus.

As well as these physical benefits there are social benefits to playing bridge.  If you play bridge you will always be able to find a local bridge club or like minded people to enjoy a game of bridge with.  You will enjoy an active social life, meeting new people and making new friends.  Very important if you are getting older, but equally important for younger people as well.

Even if you are unable to leave your house, you can join online bridge rooms where you can play bridge against real people.  The internet is a huge benefit to anyone with an illness or disability, allowing you to make friends, chat and interact with people that you would otherwise never meet.

So what are you waiting for?  Join No Fear Bridge and learn or improve your bridge play today.  It can help improve or maintain your physical and mental health.

How to Use Statistics to Improve Your Game Play

Millions of people enjoy playing bridge and millions of players understand the basic rules of the game. They practice and play every day. Many reach a certain level of expertise and then plateau. Their game stops improving.

What's responsible for this plateau? For many the answer is statistics. Or to be more accurate, a lack of understanding or knowledge of how to use statistics when you are playing.
What do statistics have to do with playing bridge, I hear you ask? The answer is "a lot". They can be, and often are, the barrier to becoming a better bridge player.

Let's assume, for example, that you are declarer. Once the opponents have made their opening lead dummy's hand is exposed for all to see. You know which cards you hold and which cards dummy holds.

Now assume that you are playing a trump contract. Dummy holds 5 cards in trumps and you hold 4, a total of 9 cards. That means that your opponents hold 4 trump cards between them.
You need to plan your play. Depending on which cards you hold in trumps you may need to try and work out how the trumps are split between the opponents. A 4-0 split may mean the game plays very differently from the way it would play if there was a 2-2 split.

You can't know for certain how the cards split in any given situation, but you can use statistics to give you a better chance. Then you can play for the most likely scenario - the percentage play. This won't always work, but over a number of games it will give you the better chance of winning more games.

As you might imagine, there are a lot of statistics associated with playing bridge. The best players will have memorised and will use all of them. Those of us who are more modest, home or club players will just remember a few - the ones that we think will be most useful to us and that we will be able to understand use.

So, back to our trump split. While we are planning our play it may seem to us that a 4-0 trump split between the opponents will need us to play differently from a 2-2 split, or a 3-1 split. We can't know how they split and we might not be able to plan for all 3 scenarios. So which should we choose as the most likely?

Statistics tell us that the probability of a 4-0 split is 10%. However, the provability of a 2-2 split is 40% and the probability of a 3-1 split is 50%. It probably doesn't make sense to plan for a 4-0 split - although if it becomes obvious early on that the cards split that way, you will want to rethink your plan.

In a scenario where a 4-0 split could have a major effect on the number of tricks you win, you may feel that you want to test the split early on in the game by drawing a round of trumps (or whichever suit is of concern). If one of the opponents shows out in the first round, then you know you are up against a 4-0 split and can replan your play.

If testing the split isn't possible, then you will probably want to make the percentage play and hope your approach pays off.

If there are 5 cards missing from a suit, the percentage chances change. The probability of a 5-0 split is just 4% (and the opponents may have helped you work out if that is likely to be the case by bidding that suit). The probability of a 4-1 split is 28%, but the probability of a 3-2 split is 68%. You will probably want to make your initial plan on the assumption of a 3-2 split.

Planning your play is an essential skill, and knowing some basic statistics will help you plan. But bridge is a dynamic game and you need to be prepared to rethink your plan if the opponents wrong foot you, or the statistics don't work in your favor.
