I play Acol with 4 card majors. Tonight I opened this hand 1 Club, despite remembering the 'rule' that with two five card suits you open the higher ranking one. I was worried that If I opened 1♠ and partner responded 2♦ I would have to show my five clubs at the 3 level and then at the 4 level. I thought that by bidding 1♣ and then 1♠ and 2♠ I would have described my hand at two levels lower but only told a little lie about my Club suit, worth it I thought.
As it turned out my partner had good Clubs so we bid and made 6NT while everyone else made 4♠ plus one or two. Maybe that was because we had more room to communicate.
Afterwards one player said we were lucky because I didn't follow best practice and it just happened to fall our way this time.
I have checked up, and the EBU system file says always bid the higher ranking 5 card suit, so does the Bernard Magee Basic Acol cribsheet, but Klinger and Brunner say that Clubs & Spades is an exception. My Club suit is better than my Spade suit. Would my bidding be different if the two suits were reversed?
