* open your better minor if you are playing 5-card majors
An opening bid shows 12 or more high card points although, if you have a long suit, you can open with 11 or occasionally 10.
You’re trying to find a suit you and your partner both like and, by opening with a suit at the 1-level, you can show partner where your length is.
If you have a 5-card suit, go ahead and bid that suit and, if you are lucky enough to have two 5-card suits, open the higher ranking.
If you don’t have a 5-card suit, open your lower ranking 4-card suit*.
*If you’re in the USA or playing 5-card majors don’t open 1H or 1S unless you have 5 of them. In those circumstances, open your better minor suit, even if you only have a 3-card suit.
