The only time you cannot make weak two openings are when you have 6 club cards and less than 10 HCP, This opening is saved for showing your partner that you have 23+ points.
You can make a preemptive overcall, a jump overcall showing weak points but a good suit.
With a 6 card suit but not enough points to open at the 1 level
Pre-emptive Opening Bids
Weak Two Opening bids are a preemptive bid. Weak Two bids tell your partner that you have at least a 6-card suit and 6-10 HCP with two or more high-cards in the bid suit. Generally bidding Weak Twos does not exclude a 4 card side-suit holding.
Guidelines for Weak 2 Bids
1. If the preemptive bid is a Major suit, then you are usually telling partner that you don’t have any interest in the other Major suit
2. A preempt as an overcall after the opposition open at the one level should be at least one level higher and in a higher-ranking suit than the opening bid.
3. If the preemptive bid is an overcall – then your preemptive overcall should be at least two levels higher (a jump overcall).
4. You are showing that you do not have an opening hand – otherwise you can double or just make a simple overcall.
5. When deciding to make a Pre-empt the vulnerability, and counting the number of winning/losing tricks should be carefully considered.
