Pre-empt opening bids make it difficult for the opponents as they have to overcall at a higher level.
To open with a weak 2 you need:
- between 6 and 9HCP.
- A 6 card including 2 high honors (ace, king or queen) in ♦, ♥ or ♠
- This means 4-6 tricks, according to whether you are vulnerable or not.
A reminder of the requirements for a weak 2 opening bid in 1st and 2nd seat:
- Not to possess 2 high honors in any other suit
- Not 2 aces
- Not 4 cards in the other major
