東家PASS之後，南家15點5張方塊KQJXX，以1D開叫，北家手持9點7張梅花AKQXXXX，以3C回應，南家以3NT束叫。

西家首攻黑桃2，莊家以黑桃Q定住，莊家連拔7墩梅花，剩下5墩，讓東西家紅心A、方塊A，共贏得3墩，東家回攻黑桃K，莊家以黑桃A定住，最後莊家續拔方塊K，3NT合約超吃一墩，得到630分。

南家以1D開叫，北家以3C回應，南家以3NT束叫，這種叫牌只有一個道理，三無王勝五線低花。

西家首攻黑桃2，純粹以供無王合約，以最長門第4 張大牌，可惜西家黑桃KJ，原本可以剋住莊家黑桃AQ，如果莊家連拔黑桃AQ，接著連拔夢家7墩梅花，3NT即可完成合約，600分入袋。

如果東西家先拔紅心AK，贏得2墩，再攻紅心讓莊家紅心Q定住，莊家連拔梅花7墩、黑桃A，西家掌控方塊A黑桃K紅心10，這3墩再輸掉，3NT合約倒掉1墩，得分又+630分，變成-100分。

首攻規則是針對平均牌型，可惜面對不平均牌型，攻守之間，似乎先把握可行性高的牌，把難題交給對手，讓莊家黑桃AQ，逃不過西家黑桃KJ關卡，勝負所在就是這裡。

Casablanca | Bertie Higgins | (Loop Lyrics)

I fell in love with you watching Casablanca

Back row of the drive-in show in the flickering light

Popcorn and cokes beneath the stars

Became champagne and caviar

Making love on a long hot summers night

I thought you fell in love with me watching Casablanca

Holding hands neath the paddle fans

In Ricks candle lit cafe

Hiding in the shadows from the spies

Moroccan moonlight in your eyes

Making magic at the movies in my old Chevrolet

Oh a kiss is still a kiss in Casablanca

But a kiss is not a kiss without your sigh

Please come back to me in Casablanca

I love you more and more each day as time goes by

I guess therere many broken hearts in Casablanca

You know Ive never really been there so I dont know

I guess our love story will never be seen

On the big wide silver screen

But it hurt just as bad when I had to watch you go

Oh a kiss is still a kiss in Casablanca

But a kiss is not a kiss without your sigh

Please come back to me in Casablanca

I love you more and more each day as time goes by

Oh a kiss is still a kiss in Casablanca

But a kiss is not a kiss without your sigh

Please come back to me in Casablanca

I love you more and more each day as time goes by
