Precision - Forum

Welcome to my Precision Bidding System Home Page. Page two has been added here You are visitor number  since 1st June 1999.

This page is intended to be an area where Bridge Players who use strong 

club systems can post and  retrieve information and ideas on bidding using

 these systems.

I have called it a Precision Page because that is the system I have used 

with my favourite  partner for 10+ years but contributions are welcome

from players using any system.  To see a directory of some bridge links

One area where we were consistently getting bad results was when partner had a balanced postitive response to a 1 club opening and bid 1nt. This often put the strong hand on the table and made it easier for defenders to get a good score. It also meant that the hand was played from the "wrong" side,going against the room.

A solution to this problem is to invert the meanings of a positive one spade and 1nt response. A positive response of 1 spade shows 8/9+ points(no upper limit) and no 5 card or longer suit, while a response of 1nt shows a positive response with 5+ spades. You can use any follow up system you like but the following scheme is comprehensive, easy to remember and has the attraction of not disclosing the openers hand to the opponents in the bidding. Examples Opener - Responder 1 c 1 s (8/9+points) No 5 card or longer suit. 1nt (tell me more) 2 d = 4 card heart suit may have 4 spades 2 h = 4 card spade suit denies 4 hearts 2 s = No 4 card Major All these responses limit the responders hand to at most 13 hcp. The follow up sequences for hands where responder is limited to 13 hcp are: Opener Responder 2 of the Major shown by responder sets the trump suit and you can use whatever follow up system you wish from there. 2nt asks responder to further describe his hand and rebids are 3 clubs/diamonds = 4 card suit 3 spades = 4 card suit (when responders first rebid was 2 diamonds showing a 4 card heart suit) Where responders first rebid denied a 4 card Major (i.e. was 2 spades) a rebid of: 3 hearts/spades over openers 2 nt shows 3 cards in the suit bid, 4-4 in the minors and 2 cards in the other Major. With 14 or more hcp, responder bids as follows Opener Responder 1 c 1 s 1nt (tell me more) 2 nt = 14+ hcp only one 4 card suit 3 c = 14+ hcp 4 clubs and another 4 card suit 3 d = 14+ hcp 4 diamonds and a 4 card Major 3 h = 14+ hcp and two 4 card Majors The follow up sequences are: Opener Responder 1 c 2 nt = 14+ hcp only one 4 card suit 3 c (tell me more) 3 d/h/s = 4 card suit 3 nt = 4 card club suit Opener Responder 1 c 3 c = 14+ hcp 4 clubs and another suit 3 d (tell me more) 3 h/s = second suit Opener Responder 1 c 3 d = 14+ hcp 4 diamonds and a Major 3 h (tell me more) 3 s = spade suit 3 nt = heart suit This scheme has several advantages: (i) If the hand is played in NT openers hand is completly undisclosed to the opponents. (ii) It is possible to include positive hands with any 4441 distribution in the 1s response (so eliminating the old "impossible negative"). This is done by having reponder bid 2c over the opener's 1NT rebid and opener can relay with 2d to learn where the singleton is. Responder bids the suit below the singleton. The limit for responder in this sequence is 9-13hcp. With 14+ and a 4441 hand I suggest responder's first bid over 1c is 2s. 2nt rebid by opener asks for the singleton and again this is shown by bidding the suit below it.
