My partner opened 1
or 1
. Does he really have a suit?
The vast majority of the time, 1 and 1 openings show hands with a real club or diamond suit. Normally we open with one of our longest suit (or 1NT with the appropriate strength and distribution). The only time a problem occurs is when our longest suit is a 4-card major, and we have the wrong strength to open 1NT.
That means there are only four possible problem distributions:
1) 4-3-3-3, such as 
KQ87 
987 AQ8 QT4
2) 3-4-3-3, such as J85 AQJ6 KJ2 AK9
3) 4-4-2-3, such as A964 JT65 K4 KQ4
4) 4-4-3-2, such as Q985 KQJ4 QJ3 K8
In Standard American, hands 1, 2, and 3 are opened 1, and hand 4 is opened 1. (Always open 1 with 3-3 in the minors.) This style is often called «convenient minor.» Some partnerships agree instead to open «better minor» and open hand 1 with 1. Others agree to play a «short club» open all four of these hands with 1.
Outside of North America, bidding a 3-card suit is commonly called a prepared minor opening, because this bid is made in preparation for a easy rebid:
- If partner bids your 4-card major, raise.
- If partner responds 1 to 1 (or 1
to 1 and you have Hand 1), bid your 4-card major. - Otherwise, bid 1NT (13-15) or 2NT (19-20).
- Only if the bidding goes 1-2 or 1-2 and you have a weak hand are you forced to pass and run a slight risk of having only a 7-card fit.
Now, let’s go across to the other side of the table, and see whether we need to worry about partner having his suit or not:
