6 System Note 1) Two-way after - 1MA 1MA* *Can have longer diamonds if < 10 p, and promises only 3-4 hcp. ** **either natural 17+ hcp with 5+ cl and 4+ diamonds or balanced with 4 card support in the bid major suit. Further bidding: 1 to play if opener has bal. with 4- card support. Natural diamond bid 17+ with 3 triple. Responses in this sequence are: 2NT 3mi 3NT 4mi 4 natural NF natural NF natural NF natural NF natural, invitational to play 1 GF against all variants. Opener can then bid further as follows: 2NT / 3 3NT 4 / 4 Natural +, minimum with stopper. Natural, descriptive bal, 4-card supp,.

The club-diamond hand bids as natural as Possible. 3 from opener establishes spades as trumphs.

7 System Note 2) 2 relay after 1MA-1NT 1 Main principles: After the opening 1 MA, the 1NT response either shows 4-10 HCP without MA supp. Or 3-7 hcp with 3 card support. After 1 opening, the weak 3-card support hand may contain 4 or more! Jumps to the 3-level from opener are non-forcing, showing p. Gameforce is established only by initiating with the 2 relay o Except for the direct jump to 3ut which shows balanced After 1M-1ut-2 shows maximum, 8-10 hcp and GF, except if opener bids 2 in her opening suit 2 in the opening majorsuit shows all minimum hands with 2/3 card support All other bids on 2 show minimum and 0-1 in the opening major suit, except for 1 1ut 2 which shows 4-7 and 5+ and After GF bids following the 2 relay, we use most bids to show the hands that are not easily bid using the strong 2 club opening, typically 2-suiters, assuming that a strong 6+major opening will open 2 clubs. The system if OFF if opponents interfer! Sequences: 1-1ut? pass 2 rare looking better than eg all distributions (except balanced) or with 5 and 4+ or balanced (5332 distr. also with double ) = maximum, min 2-3, other min. 0-1 see below HP, 5 and 4, or 5-5 and 10-12p = 2ut max. and support, 3 5- card suit and min points, 6-7, or Majors p, 5-6 in majors 2ut Hcp, 6 hearts and 4 i a minor =?, 3 other is pass or raise (shows the suit = raise if you also have clubs ) Hcp, 5-5 in / Hcp, 5-5 i / 12-16, Hcp 6-7 farve i Hcp, 5-6 i major 1 Strongly inspired by the Gazilli convention 3

In our version of 1X-1Y-1nt we can stop in by passing after 2. We can stop in using 2ut directly after 1nt (NB!) The convention is played undisturbed and after opponents double, but not after their 1 or two level overcall 1X-1Y-1 ut 1x 1y 1NT 2 Relay to.

11 System Note 4) When opponents show a known-two suiter The convention is used when opps overcall showing a two-suiter in known suits. The options are as follows pass dbl Overcall in the nearest Of the opponents suit Overcall in the farthest of the opponents suits Interest in penalty in at leas tone of their suits Double from opener is penalty. GF without primary fit to opener s suit (typically showing length in the fourth suit) GF with fit to the opening bid 4. suit natural, NF Direct support natural, NF AFter our opening and response in a new suit followed by a 1/2NT overcall from opps in 4th position, we use the convention to show either a standard bid or a minimum bid just showing distribution. Ex. 1 pass 1 2NT? Pas Dbl 3 3 natural Interested in penalty in at leas tone of their suits A standard 3 -bid, that is suit 6+, minimum Invitational or better with spade support Minimum with supp. just competing for the contract. 1x pass 1y 2NT dbl pass pass show a balanced postive hand, as 3x is weak 3y shows 8-11 with a 6+farve 1x pass 1y 2NT dbl pass pass 3z dbl/pas pass 3/4y GF with a 6+suit 1x pass 1y 2NT pass 3z pass pass dbl strength/take-out dbl 7

12 System note 5) Opponents interfer on our 1NT opening The system is off, except if 2 or double show a one-suiter (e.g Capelletti). The double of 2cl asks for majors (Stayman) and 2 after their double (one-suiter) is also Stayman (RD is strength and doubles after this is penalty). The opponents double 1 NT ( ) Revised Sundelins Sprattlinger Pass Rdbl To play (the cheapest option or 8+). When opps bid, we have 1 take-out double together + another suit 2 or + a major If opps double or both Major If opps double: natural 5+ natural 5+ pass = RD = + = + RD = both M equal length or best = both Majors, longest / best 2NT GF - a hand which will not play 1nt doubled. Natural bids from here. If the opps double a (18) nt we play natural also RD, unless opps double shows a one-suiter (system on). 8

13 Rubensohl Is used when We open 1nt and opps overcall bids on the two-level We double opps 1 nt opening (RHO) and they (LHO) overcall on the two-level We overcall 1nt on opponent s opening 1x, and they (LHO) overcall on the two-level The principle is to use transfer bids as invit+. The invit may be weak as nt bidder only bids game with super-max and /or fit. We use the transfer to the opps suit to ask for a stopper. 3 is both minors 1NT 2 double = points something in, (take-out if are natural) nat, NF 2MA shows stopper, if 2 = both M, otherwise natural NF 2NT: 5+, weak invit+ : 5+ weak invit+ 3 : 5+ weak invit+ : 5+ weak invit + 3 : at least 55 minors FG 3NT: to play 1NT - () - double = points something in diamonds if is articifial and = take-out if 2 diamonds is natural 2M nat.

14 System note 6) Multi opening 5+ in a major, 0-7HCP. In 1 st and 2 nd pos, if only a 5 suiter, it has values in the suit, ex.

If partner has not passed, we follow strictly the rule. On the overcall 1M we play OSTOT responses from 1nt if the opp passes or doubles! 11

16 System Note 9): Reverse Trelde signalling Is used against suit contracts when we lead an honour (EKQJ) in a suit - which we opened with and were supported in (e.g. 1sp 3sp) - which partner has bid or overcalled. We play, - Small = encouraging in the suit - High Even = signals to the lowest side suit, not trumph - High Odd = signals to the highest side suit not trumph 7,8,9,10 are prioritized. Sometimes we do not have the right card. Partner must evaluate this depending on her own holding of even/odd cards. If 7-10 are not available, we may afford to play and honor eg. the jack. 12
