Meaning of the opening: 10-16 HCP, 5+ suit (5M-6m is possible)
- 1♠: | 4+ suit, F1. If you have 3-card fit, then 5+ ♠. With a gameforcing hand 2♣ can be bid too. |
- 1N: | Nonforcing, but may have invitational hand ("semiforcing"). Denies 3-card
fit and 4-card ♠, about. 6-12 HCP. (see also: 3m)
Opener:
|
- 2♣: | Artificial GF, relay. It should be bid with most GF hands. |
- 2♦: | (on ♠): transfer to ♥. Can be weak with 6+ suit, otherwise INV+. |
- 2M-1: | 10-12 dp, 3 (rarely 4) cards support. Opener calculates with a relative weak responder hand, her bids above 2M are according to CSLT, 2M is weakness. Responder can bid on after 2M, according to CSLT too. |
- 2M: | 5-9 dp. (i.e. weak hand). CSLT on this (but only with big hands!). 0-5 is possible in NV / V. |
- 2M+1: | mini/maxi SPL: 4+ trumps, cca. 6-8 HCP or 14-15 HCP. Relay asks,
- S123: mini SPL - S4 (3M+1): maxi SPL with a void, - L567: maxi SPL with singleton. (these ones are the same on 3M signoff) |
- 2N: | (on 1♥):
limit (11-12 dp.) raise with 4+ trumps (Bergen). Now:
- 3m: singleton, weak hand (perhaps responder likes it), or slam try - 3M+1: slam try with 2-suited hand, bids the side suit on a relay - 4m: void, slam try (ORKC) |
- 3m: | game try with a (good) 6+ suit, denies 3-card fit and 4-card oM (with that 1♠/1N) |
- 3♥: | (on 1♠): limit Bergen, same as 1♥-2N. On this 3N is slam try with 2-suited hand (bids the side suit on relay), 4x slam try with shortness (SPL, S1 = RKC, 4M is misfit) |
- 3M: | 4+ trumps, 0-7 dp, some shape (with a balanced trash you may bid 2M) |
- 3♠: | (on 1♥): natural, nonforcing, 7+ suit, cca. 6 playing tricks |
- 3N: | SPL oM |
- 4m: | SPL, can be void too. Cca. 11-13 HCP in case of 4 trumps and singleton (Now S1 = CYS, S2 = (O)RKC) |
- 4M: | may have relative strong hand when slam looks unlikely |
- 4oM: | natural |
1♠ | - | 2♦ | transfer to hearts: weak hand with 6+ suit or game try with 5+ suit or special slam tries | |
? | Opener bids to the weak hand. |
- 2♥: | Can be short without a better bid. On this one:
|
- 2♠: | 6-card ♠, at most doubleton ♥ |
- 2N: | very good hand with singleton heart |
- 3m: | good 5-5 |
- 3♥: | 4-card ♥ or strong hand with 3 cards |
- 3♠: | big hand with good 6+ ♠, which can played opposite a singleton |
1♥ | - | 1♠ |
? |
1♥ | - | 1♠ | Opener: 5+♥-4♠, not minimal. | |
2N | - | 3♣ | GI+ relay | |
? |
- 3♦: | short ♣. On this one:
- 3♥ game try (in ♠, because we cannot have more ♥s, than ♠s) - 3♠: sign-off (does not like singleton ♣ at all) |
- 3♥: | short ♦, weak |
- 3♠: | short ♦, strong |
1M | - | 2♣ | GF relay | |
? |
- 2♦ | 6+ major. On this 2♥ is relay |
- 2♥: | (a) 5M-4+ ♣ (3♣...3N, at second round, like with oM) or (b) 5332, 2N at second round, then the doubleton on further relay, the rest are NAT, asking for cue bid with good hand and support. |
- 2♠ | 5M-4+♦. On a 2N relay the same bids as direct 3♣...3N |
- 2N: | 5440. Bid your void on a 3♣ relay |
The rest promises length in the other major. The same bids will show the same distribution after the second relay on 2♥♠ | |
- 3♣...3N: | 5-5 or 5-4 according to the compact two-suiter scheme |
- 4x: | very good 6+ major and lower range, SPL |
1M | - | 2♣ | GF relay | |
2♦ | - | 2♥ | 6+ major | |
? |
- 2♠ | One-suiter. Continuation according to the 1-suiter scheme. |
- 2N: | 4-card ♦ |
- 3♣ | 4-card oM . Continuation according to the compact 2-suiter scheme. (with 7-4, and good major, bid your void on level 4 after the relay) |
- 3♦...3N | 4-card ♣
, short ♦ / singleton oM / void oM- / void oM+ There is a special continuation with short ♦: |
- 4x: | very good (at most 1 loser) 6+ major, upper range, SPL |
