2.4 Interference Over 1C Opening Over a double all responses are on. Over an overcall the following responses indicate: Pass = negative response (same as the normal 1D bid) with no good 5-card suit and less than 8 HCP. New suit = “maximum negative” response with a good 5 or more good cards in the suit bid and 5 to 8- HCP. Cue-bid = positive response with 8 or more HCP. Notrump = positive response with the usual 1NT, 2NT or 3NT Precision meanings as if no overcall was made. Promises at least one stopper. Double = penalty (used only if the opponent’s bid is a real suit).

2.5 Precision Asking Bids (Optional Convention 2.5.1 The Trump Asking Bid Used only when 1C was opened and responder bid a REGULAR POSITIVE SUIT response. Used when inquiring about the value of responder’s trump suit. A simple raise of responder’s suit by opener is a Trump Asking bid Responder’s step responses indicate the following: One step = POOR trumps - Jack high or worse. Two steps = FAIR trumps - one of the three top honors. Three steps = GOOD trumps - two of the top three honors. Four steps = EXCELLENT trumps - all three top honors.

Example: [ 1C Pass 1S Pass ] ; [ 2S Pass 3D 2S is the Trump Asking Bid for spades. Responder's 3D shows two of the top three honors. To just raise responder and bypass Trump Asking, the opener rebids 1NT (forcing) then over whatever responder rebids, opener will then rebid responder’s first suit. Example: [ 1C Pass 1S Pass ] ; [ 1NT Pass 2C Pass ] : [ 2S 1NT is forcing. 2S shows a simple spade raise, thus bypassing the Trump Asking bid.

2.5.2 The Control Asking Bid Used only when 1C was opened and responder bid a REGULAR POSITIVE SUIT response. Used after a Trump Asking bid has been answered by responder. After responder has answered a Trump Asking Bid, a new suit bid by opener at the cheapest level is a Control Asking bid. Opener wants responder to shows controls in the newly bid suit by step responses. Responder’s step responses indicate the following: One step = POOR controls - no Ace, King, void or singleton. Two steps = GOOD controls - King or singleton. Three steps = EXCELLENT controls - Ace or void.

Example: [ 1C Pass 1S Pass ] : [ 2S Pass 3D Pass ] : [ 3H Pass 3NT 2S is the Trump Asking Bid for spades. Responder's 3D shows two of the top three honors. 3H is the Control Asking Bid for hearts. Responder's 3NT shows a King or singleton in hearts.

Mathe Defense Against a Strong 1C Opening A simple defensive bidding scheme. May also be used against strong 2C openers (all bids one-level higher) 2C = clubs 1D = diamonds 1H = hearts 1S = spades Double = both majors 1NT = both minors
