Reverse Drury Convention

Reverse Drury convention is invented to show maximum hand with 3+ card fit with 2♣ bid as a passed hand, when partner opened 1 major in the 3rd or 4th position. Using Reverse Drury convention , we can stop many times in level 2,  we get back natural 2NT, 3♣, 3 bids, and we can be sure of having or not having fit immediately, what is a great advantage.

We bid  2♣ bid as a passed hand with all 3+ card fit, except Splinter hands, when partner opened 1 major in the 3rd or 4th position. A Splinter bid from passed hand has to consider, that opener may be weaker, than usually. Therefore I suggest to play it only with 4 Italian controls, nice hand and 4 card fit, (not with a poor 4-4-4-1 hand, that should go to delayed Bergen and still we can bid game later) or 3 controls, nice hand and 5 card fit. (Ace is 2 control, King is 1 control)

Reverse Drury is another convention, which has to be changed in order to work better: original Drury convention, although the idea is genial, asked 2 with minimum hand, giving the possibility for the defensive side to find  and  fit in level 2, when we have ♠, which is wrong.

Bidding 2♠ with minimum hand, we force left hand opponent to intervene in level 3, although he didn't bid to 1♠, which is much more dangerous.

It is very important to agree not to play Bergen at the same time. We can introduce all maximum hand with 3+ card fit via 2♣ or splinter bids, and we need the natural weak 3♣ bid an the game invitational 3 natural bid.

We can play delayed Bergen after 2♣, we bid 3♣ later with singleton and 4 support and 3♦ without singleton and 4 support, instead of natural bids. This solution is working very well.

After 2♣, the 2 major is weak from both sides, 2 is an artificial waiting bid, either re-inviting, cca 14 points or slam invit hand.

The new suits from both side will be natural, and the jump bids will be splinter.

It is very important to bid 2 major stop bid to 2, when we have bad hand, also when we have an interesting value in our hand. Partner can discover it later, when he needs it, but we cannot stop in 2 major when partner is very weak, and we go above 2 major!

It is also important to find the 4-4 other major fit, because it is very often bringing more tricks, than 5-3 fit. It is easy, when we opened with 1♠, because we simply bid 2 instead 2 to partner's 2♣, when we have 4+.

When we have 4 card ♠ and game forcing hand, we can bid 2♠ to 2♣. When we have to bid 2 to 2♣, partner can simply ask our ♠ card number, asking with 2♠ relay.
