ACBL Pre-alertable Openings:
1 ![]() 1 ![]() 1M = possibly canape Overcalls (not ACBL pre-alerts): (1 ![]() ![]() ![]() (1 ![]() (1 ![]() ![]() ![]() ![]() 2 cheapest jump overcalls at 2-level show that suit and the next higher ranking suit. Other opening bids, responses and competitive calls that may require advance preparation, but are not ACBL pre-alerts are listed at the bottom of the general bidding style. In general, people like to make defenses against 1 ![]() ![]() ![]() ![]() ![]() ![]() ![]() or (1X) – 2 ![]() |
Strong ![]() [For points listed here, we routinely upgrade HCP ranges according to ACBL's Rule of 17/19 (e.g., 5-5 Majors 9HCP will routinely be upgraded to a 10 to 14 artificial 1 ![]() List of Openings: 1 ![]() ![]() -1st/2nd 10 to 14 nf; -3rd/4th NV14+ to 17 V13+ to 17, unbal forcing usually no major unless 4M-7m 1 ![]() ![]() ![]() -1st/2nd 15 to 37; -3rd/4th 18 to 37 1 ![]() ![]() -1st/2nd NV 8 to 10-; VUL 8 to 11 -3rd/4th NV 14+ to 17, VUL 13+ to 17 1 ![]() ![]() ![]() -1st/2nd NV 8 to 9; VUL 8 to 11 -3rd/4th NV 14+ to 17, VUL 13+ to 17; 4+ ![]() ![]() ![]() 1NT = Natural, or a natural N; -1st/2nd 12 to 14; -3rd/4th 15 to 17, no 4+Major 2 ![]() -1st/2nd NV 0-6 ![]() ![]() ![]() ![]() -1st/2nd VUL no 4+M; Both VUL, 0-6 ![]() ![]() ![]() ![]() -3rd 5+ 0 to 14 NV 0 to 13 VUL -4th 5+ 13 to 14 2 ![]() -1st/2nd NV 5+ ![]() ![]() ![]() ![]() -1st/2nd VUL 0-4 ![]() ![]() ![]() -3rd 5+ ![]() -4th 5+ ![]() 2 ![]() ![]() -1st/2nd: 10 to 14, 5 ![]() ![]() ![]() -3rd: 0 to 14 NV, 0 to 13 VUL -4th: 13 to 14 2 ![]() ![]() -1st/2nd: 11 to 14, 5 ![]() ![]() ![]() -3rd: 0 to 14 NV, 0 to 13 VUL -4th: 13 to 14 any distribution 2NT = 6-7 ![]() ![]() -1st/2nd: 15 to 17 -3rd/4th: 18 to 19 3NT = solid minor -1st/2nd: no side A or K -3rd/4th: Gambling/Preemptive, expectation game can make vs. a random 5 count but slam is unlikely 4m = NAMYATS 8.5 tricks+, long Major two steps higher Psychics/awkward situations where we violate system: We tend not to be crazy third seat because we are systemically crazy first and second. Have rarely opted to show Kx when holding stiff K in relay or add a card to AQ and subtract a card from xxxx; rare because it will be two cards off actual pattern. When we cannot show 8+suits, 7411 or 12+ cards in two suits in relay so have to represent another pattern if responding to relay. Forcing pass: We play pass double inversion when one of us has made a game forcing bid. This does not apply to a game raise. In some invitational sequences (e.g., 1 ![]() ![]() 1 ![]() ![]() Relay notes: For all openings 1st/2nd through 3 ![]() 1 ![]() (1X) – X – (1NT) is high enough 2nd, we do not play relay after 3rd and 4th seat power doubles 1 ![]() 1M – (1NT) is high enough 1st/2nd if it is natural or shows 2 known suits otherwise 2 ![]() 1N – X is high enough if it cards/penalty/takeout or shows two known suits, (2 ![]() ![]() 2 ![]() ![]() 2 ![]() ![]() 2 ![]() ![]() 2 ![]() 2NT – (3 ![]() ![]() 3 ![]() ![]() To interrupt relay once started, Typically 3 steps Before pattern is shown, if there is one-step interference (e.g., 1 ![]() ![]() General style: We play a strong diamond system with many weird openings, competing calls and follow ups. In the 15 to 37 range in 1st and 2nd seats we have 2 calls: 2NT = artificial, 6+ ![]() ![]() 1 ![]() In 1st and 2nd seats in the 10 to 14 range we have six calls available: 2M = natural; -5M4m(31) or a 6M0-3oM; -10 to 14 1NT = 10 to 12 HCP, natural or natural NT pattern but with a small singleton, but still NT oriented: (4441), 6m(331) 1 ![]() ![]() 1M = 8 to 9NV/11VUL 4+M could have a longer side suit, 1 ![]() ![]() -We prefer to open 2M or 1NT to 1 ![]() ![]() In the 8 to 9 range we can either open 2m not unfav, at the 3-level or above or, if we have a 4+card major, we open 1 of a major. We will prefer 1M to 1 ![]() 10 to 11VUL hands with 4+M 7- losers we tend to avoid 1M and instead bid 2M, 1 ![]() Our style is NV to open all 10 HCP and all 8+HCP strength hands with a 4+M. Equal vul we pass 10 to 11 4m4m32/4m333 unless upgrade. Unfavorable we also pass 10 HCP 5m332 and 8-9HCP6m unless 7 tricks. We can upgrade or downgrade (with some exceptions imposed by the Open+ chart like not being able to upgrade from less than near average to near average to open 1M or from near average to average to open 1 ![]() In 3rd and 4th seats, since we already opened (almost) all 10+ and most 8+ hands, we increase the strength requirements for our strong bids to 18+. We add another forcing opening: 1 ![]() In the 15 or higher range, we have 6 bids 1 ![]() 1 ![]() 1M = 4+M 13+VUL/14+NV to 17 1NT = 13+VUL/14+NV to 17 denying 4+M; either natural or (33)(61) with a small singleton. 2NT = 6 ![]() ![]() In the less than 15 range we play 2X natural and 3C+ 2X = 5+X -3rd 0 to 14 NV, 0 to 13 VUL and no distribution requirements, but will pass instead with high losing trick count hands that vary by vulnerability -4th seat, it is 13 to 14. In 1st/2nd we will pass non-preempts with 0-7 with a M, 8-9 no Maj and V also 10 to 11- 7.5+ loser hands with no Maj and do not qualify for 2m. In 3rd seat, we will pass 0 to 14- NV, 0 to 13-V hands with no 5 card suit, in 4th also pass with 0 to 12 and a 5 card suit.

4th from suits we like v. NT ATT leads breaking new suits in middle of hand (lead lo like) standard honors except big king vs. NT ATT leads vs. NT in a suit that the defenders bid Suit pref leads possible (e.g. giving ruff) Standard honors except big king vs. NT |
