Responses to Two Clubs

In a Nutshell

The bane of any system of nonforcing one-bids is the 2 C structure for strong hands; there just isn’t enough room to show all you want no matter what method you use. Having experimented with many ideas, I settled on what I believe works best. The basic idea is to give the 2 D response a dual meaning, either ultra weak (0-4 HCP) or positive (8+); and to bid 2 H with in-between hands (5-7). Other responses are used to show suits of specific length and quality. TopMain

Details

An opening bid of 2 C is strong, artificial and forcing, typically 23+ points or within a trick of game in hand.

Responder must either categorize his HCP range or show a suit headed by K-Q or better.

After two-diamond response

Responder is presumed to have 0-4 HCP for all rebids. With 8+ HCP (or ace + king) he bids the same as with 0-4 under game but must continue voluntarily past game to show it.

*if responder bids again, follow opening 2 NT structure 1 or 2 levels higher.

All doubles by opener or responder are penalty, and all direct passes are forcing.

If opener bids an enemy shown suit that he could not double for penalty, it is natural (enemy bid was probably a psych).

If responder has not acted, a suit bid by opener below game is forcing, and the cheapest response is an artificial waiting bid. TopMain

Opener's suit jumps

If 2 C opener jumps in a suit at his second turn (including an enemy shown suit that he could not double for penalty) it is natural and sets trumps.
