{

North has only 11HCP, but the two longest suits: Hearts=6 and Clubs=5, added to
the 11 gives 22. This meets the Rule of 20, and so North opens 1\H.

South’s change of suit reply promises 6+HCP and four+  spades and demands a
re-bid.

North re-bids 2\C giving partner the option to return to his first suit,
hearts, at the two level. This shows a minimum opening hand, five+ hearts and
four+ clubs.

With a non-game going hand, South indicates preference for hearts, and
sign-off, by bidding 2\H. This is as far as the partnership can go, and all
pass.

East: Hearts=6, Clubs=3, add 11HCPs makes 20. This meets the Rule of 20, and so
East opens 1\H.  

West’s change of suit reply promises 10+HCP, at least four diamonds and demands
a re-bid.  

East re-bid 2\H indicates minimum opening hand, 5+ hearts, no diamond fit.
There could be four spades, but they could not be bid without showing a
stronger hand.  

East’s could be very weak, but with 12 HCPs and good cards in other suits tries
2NT. With very minimal opening, East passes. 

Eight tricks can be made if declarer ignores hearts and persists with diamonds
trying the finesse twice. }

{

South has only 11HCP, but the two longest suits: Clubs=6 and Diamonds=3, added
to the 11 gives 20. This meets the Rule of 20, and so South opens 1\C. 

North’s change of suit reply promises 6+HCP and at least four hearts and
demands a re-bid.  

South can only re-bid 2\C. 

This shows a minimum opening hand with at least 5 clubs. 

Hint: partner didn’t open 1NT, so there’s probably six clubs. It denies 4
hearts or 4 spades so maybe the hand is 6:3:2:2. 

North is best to leave well alone now and pass. }

{

West has Hearts=6 and Spades=4, and 10HCPs  adds up to 20. This meets the Rule
of 20, and so West opens 1\H. 

East’s 1\S shows 6+HCP, four+ spades & demands a re-bid. 

West raises the spades: 2\S, shows weak opening hand with 5+ hearts and 4+
spades.  \n
West’s hand could be very weak OR be 14HCPs. 

With 12HCPs East makes an invitational raise.   

West has only 10HCP, BUT a singleton Ace, and raises to the game bonus
attracting 4\S. Go for the big bonus if in doubt.  

To make the contract declarer must delay clearing trumps. Take the A\D and then
trump a diamond in dummy.}

{

North: 6 Clubs + 3 Spades + 11HCPs meets the Rule of Twenty, so North opens
1\C. 

South 1\D shows 6+HCP, four+ diamonds & demands a re-bid. 

West's spade suit is not good enough for an overcall.  

North's 2\C rebid is a minimum hand, North didn’t open 1NT, so there’s probably
six clubs. It denies 4 hearts or 4 spades so maybe the hand is 6:3:2:2. South
lets it go at 2\C.  

East has no obvious lead. 5\D suggets fourth highest, and gets two diamond
tricks for the defence. There’s the A\C and a heart tricks for the defence,
leaving declarer with nine. }

{

West: 5 hearts + 5 clubs + 10HCPs =20, meets the Rule of Twenty, so West opens
1\H. 

North makes a simple 1\S overcall showing 5+ good spades and 8-14HCPs. 

The HCP’s look to be evenly distributed.   

The heart/spade competition continues until the vulnerable  pair, East / West,
decline to go to the four level.

3\S made scores 140; with overtrick 170. Two down vulnerable for East / West
gives away 200, so its not worth the risk. 

As it happens 4\H will make. That’s bridge.  }

South: 5 diamonds+4 hearts+11HCPs=20, South opens 1\D. 

North 1\H shows 6+HCP, four+ hearts & demands a re-bid.  \n
(Show the major rather than raise diamonds.)

East bids a simple 1\S overcall, 5+ good spades, 8-14HCPs.

With eight+ hearts between the two hands, a double fit (hearts and diamonds),
and a \S singleton, South bids the hearts game.  

Declarer has one spade to lose, but can then trump a spade in dummy, so keeps
one trump there. The K\H is missing but the finesse will succeed because it is
on the “right” side. There is one club to lose because the king is on the
“wrong” side. The Diamonds are solid, so eleven tricks are winnable. }

{

West: 5 diamonds+4 spades+11HCPs=20, West opens 1\D. 

East 1\S shows 6+HCP, four+ spades & demands a re-bid.

The re-bid supports spades at the next available level showing a weak opening
hand with 5+ diamonds and 4+ spades.   

East has distributional hand (two doubletons) and five spades, 11HCP. If West
is at the top end of a weak opening hand, the game contract could be there, and
so East invites a game call with a further raise. 

West’s hand is a lower end weak opening hand, and so passes.   North / South
never get a chance to find their heart fit.  }
