Roman 2 Diamonds

I feel that partnerships should have two strong opening bids. The 2Club opener is obvious but the 2Diamond opener should also be a strong bid. I feel established partnerships should have the Roman 2Diamond in their repertoire. Why? because strong 4-4-4-1 hands are horribly hard to bid. They usually up the range also because opening 2Club with strong 4-4-4-1 are also very hard to handle. The 2Diamond opener is a strong bid and I just treat it as a special 2Club opener but with 4-4-4-1 hands. Having strong 4-4-4-1 hands removed from your system and tucked into one bid has advantages. Other bidding sequences are now clarified as you can not hold a strong 4-4-4-1. This virtually guarantees a 5 or longer minor when you rebid a major. This treatment removes the 4-4-4-1 hands from your two club structure which also clarifies those bids. Tom and I play a jump by the 2Club opener as setting the suit and not a singleton.

A Roman 2Diamond opening bid shows any 4-4-4-1 distribution with 17-24 HCP. Responder is expected to bid his best (longest) minor suit at the 3 level with some values under a 2NT response; with little preference, he bids 2Heart. With a hand interested in playing a game (or slam) contract, responder can bid 2NT, artificial. This artificial 2NT response is also on in competition. The trick with this wide a range is describing the range variance. The following discusses ways of doing that.

After hearing a simple suit response, opener bids the next-highest suit with a minimum if responder happened to bid his short suit. Responder is then expected to correct, if necessary, to a better fit. Due to the wide HCP range of the 2Diamond, we need a way to force to game after a simple response (essentially 2Club hands). If we do not wish to force to game, we of course, will just pass after we have found a fit. If we do not have a fit, we will just bid the next suit up if we do not wish to force to game. If we wish to game force, we will bid NT with no fit or show our singleton (as long as its not the next ranking suit).

Examples:

2Diamond Pass 2Spade Pass
2NT

2NT is a game force with a singleton spade.

2Diamond Pass 2Spade Pass
3Club

3Club is just trying to find a better spot with a singleton spade.

2Diamond Pass 2Spade Pass
3Diamond

17-24 has 2 ranges 17-20 and 21-24 so the responses to 2NT can take this range disparity into consideration. You can not hold a 5 card major but 5-4-4-0 with 5 card minors are permissible.

2D - 2NT.

2NT asks and partner responds up the line in rank order with minimum taking priority over maximum and major singletons taking priority over showing minor singletons:

Over these bids since there is a void involved, 4NT asks about controls (A=2 K=1)

Tom Gandolfo was in 4th seat with SpadeAKJx HeartAK109 Diamondx ClubAKxx. Opening a club in 4th seat is dangerous as if partner with a scattering of points in a major passes you may even miss a slam. SpadeQxxxxx Heartxx Diamondxxx Clubxx or SpadeQ10xx HeartQxxx Diamondxxx Clubxx and partner might play this in 1Club instead of +1430 in spades. Anyway Tom is in 4th seat and opens 2Diamond and I hold Spadexxx HeartQxx DiamondAJxxx Clubxx. Since I have some values I should not bid a minimum 2Heart. I am not strong enough to bid 2NT but I am strong enough to bid 3Diamond. Tom just bids 3NT which is a good a contract as any. Take away my Ace and I have a 2Heart response instead.
