~2/1 Bidding Matrix

Replacement Info for the 2/1 Bidding Matrix

When partner opens 1 of a major suit, select the option below that best fits your holding and make the indicated bid. “Pieces” refers to the number of cards held in partner’s opening major suit. Total Points refers to HCP plus distribution points.

Holding 6-7 HCP, bid 1NT with 1,2,3 or 4 pieces.

Holding 8-10 Total Points, bid 1NT with 1-2 pieces but raise partner’s major two the 2-lvl with 3-4 pieces.

Holding 11-12 HCP, bid 1 NT with 1-2 pieces; with 11-12 Total Points and 3 pieces but also bid 1NT but jump raise partner’s major to the 3-lvl with 4 pieces if holding 12-12 Total Points.

Holding 13+ HCP and 1, 2, or 3 pieces, bid a new suit, except with 3-3-3-4 shape and exactly 3 trumps, bid 3NT to give partner an accurate picture of your hand. Holding 4 pieces and 13+ HCP, you may choose between three bids to select the one that best fits your holdings:
~2 of a new suit (2/1) holding a good 5-card side suit. A “good” side suit may differ in the eyes of different partnerships; I prefer the suit contain a minimum of 2 of the top 3 honors (alternately 5 HCP) in the suit.
~Holding a balanced hand, bid 2NT if playing the Jacoby 2NT convention (recommended).
~Holding a splinter (singleton or void) but no good 5-card side suit, make a double jump shift in the splinter.
