FROM “SAYC” TO “TWO OVER ONE”
Read
more about Inverted Minors in Part 5 After a major opening it is standard for SAYC or 2/1 the use of response in 2NT (Jacoby Game Force - GF) to show support 4 cards with 12-16 hcp without singleton. But when Responder’s hand has 10-11 hcp without support SAYC and 2/1 have different approaches: For SAYC it is allowed to Responder bid a 5+ cards suit at level 2 with 10-11 hcp and then pass if Opener bids 2NT showing 12-13 hcp in a 5332 distribution. For 2/1 Responder need 12+ hcp to bid a suit at level 2 (because that it is GF), so hands with 10-11 hcp without support Responder must first bid in 1NT. Then, with 10-11 hcp Responder may bid 2NT. So, playing 2/1 after a major opening Responder with 5-11 hcp has how to inform in his second bid if his range is 5-9 hcp or 10-11 hcp: A- without 3+ cards support with 6-9 hcp balanced hand then bid 1NT. Opener Responder 1♠ 1NT 2♣ ? a) ♠Jx ♥A109x ♦Jxxx ♣Qxx => 2♠ sign-off - just preference b) ♠Jx ♥109x ♦KJ10xxx ♣Qx => 2♦ sign-off – only play in his long suit c) ♠xx ♥J9x ♦K9xx ♣QJ10x => pass Opener may have 3♣+ cards d) ♠Kx ♥J9x ♦J9xx ♣QJ10x => 2♠ support with honor second B- without 3+ cards support with 10-11 hcp Responder must bid first 1NT Opener Responder 1♠ 1NT 2♣ ? d) ♠Jx ♥AJ10x ♦KJ10x ♣J9x => 2NT invitation to 3NT with 10-11 hcp e) ♠Jx ♥K9x ♦KJx ♣K109xx => 3♣ shows 5♣+ cards support and 10-11 hcp f) ♠xx ♥AQ987x ♦KJx ♣10x => 3♥ shows 6♥+ invitation for 4♥ with 10-11 hcp g) ♠Qxx ♥AQ98 ♦Kxxx ♣10x => 3♠ shows 3♠ cards support with 10-11 hcp -------------------------------------- 5- After a major opening and a minor response SAYC and 2/1 have differences concepts. SAYC loses space (for cuebids) when jumping to show a game-force hand (GF). Playing 2/1 we use the Fast Arrive Principle where jumping to game shows a minimum opening hand after Responder bids a GF. In other hand, 2/1 uses Slow Arrive to keep space to cuebid when have a strong opening hand. Playing 2/1 Opener Responder 1♠ 2♣ / 2♦ / 2♥ are GF with 12+ hcp Opener Responder 1♥ 2♣ / 2♦ are GF with 12+ hcp Opener Responder 1♦ 2♣ is GF with 12+ hcp But playing SAYC all of these possible bids shows 10+ hcp and forces the bidding until 2NT or at level 3 of the Opener suit or the Responder suit. But need jump to be GF. Thus, playing 2/1 after a response bid at level 2 in other suit up the line this starts a GF sequence and it is more easy to exchange information about distribution/suit and strength of their hand because the bidding will not stop at 2NT and nor at level 3 in Responder suit. The lemma for 2/1 in this sequence is: IN GF SEQUENCE LOWER YOU BID MORE STRONG YOU ARE. This is known as the Principle of Fast/Slow Arrive because with a minimum hand 12-15 hcp you must go to the game as soon as possible and with a hand 16+ hcp you must show your honor before bid game. But in SAYC the lemma is: STRONGER YOU ARE HIGHER YOU BID, and this demands a jump in Opener’s suit or in Responder’s suit. The jump cut space for more clarification of hand. Playing SAYC with 12-13 hcp Opener just invite Opener Responder 1♠ 2♥ 3♥ <= ♠AJ765 ♥J9x ♦KJx ♣Kx <= 12-13 hcp If Responder are 10-11 hcp may pass Playing SAYC with 14-16 hcp Opener jumps to game Opener Responder 1♠ 2♥ 4♥ <= ♠AJ765 ♥Q9x ♦KJx ♣Ax <= 14-16 hcp Playing 2/1 we use the Fast Arrive after GF Opener Responder 1♠ 2♥ 4♥ <= Fast Arrive: ♠AJ765 ♥J9x ♦KJx ♣Kx 12-15 hcp Opener Responder 1♠ 2♥ 3♥ <= ♠AK765 ♥Q9xx ♦KJx ♣Ax <= 16+ hcp The basic idea it is keep space for cuebid (A or K) 6- In the early years of bridge contract, after 1NT opening 16-18 hcp, players understand the importance of the contract being played in the long suit of Responder’s hand. Then, when Responder was 5-card major in distribution 5332 and less than 7 hcp a 5-card bid at level 2 was a pure sign-off. Opener Responder 1NT 2♥/2♠ <= sign-off pass Responder’s hands possible: ♠K7652 ♥9xx ♦Jxx ♣xx <= 2♠ ♠1087652 ♥9xx ♦AJx ♣x <= 2♠ ♠52 ♥QJxxx ♦QJxx ♣xx <= 2♥ ♠KJ5 ♥9J107543 ♦Jxx ♣x <= 2♥ Then experts play start to understand that if the strong hand receive the lead the chances of success increase and players like Oswald Jacoby (1902-1984) start to use the transfer for majors after 1NT or 2NT opening. Opener Responder 1NT 2♦ <= transfer to 2♥ 2♥ ? pass less than 7 hcp 3♥ <= invitation 7-8 hcp 4♥ <= to play 9+ hcp pass Opener Responder 1NT 2♥ <= transfer to 2♠ 2♠ <= pass less than 7 hcp 3♠ <= invitation 7-8 hcp 4♠ <= t0 play 9+ hcp pass In fact, after 1NT opening the response in 2♣ was an artificial bid asking for major suit, but then in SAYC Bidding System the 1NT responses was improve with 2♠ being a Stayman for minors or being a transfer for minors with 6 cards minors with less than 7 hcp. So, the responses at level 2 was: Responder Opener 1NT ? 2♣ <= Stayman for majors 2♦ <= transfer to 2♥ 2♥ <= transfer to 2♠ 2♠ <= Stayman for minors 2NT<= invitation or Responder Opener 1NT ? 2♣ <= Stayman asking for majors 2♦ <= transfer to 2♥ 2♥ <= transfer to 2♠ 2♠ <= transfer to 3♣ 3♣ <= pass or correct So, Responder pass with 6♣ cards or bid 3♦ pure sign-off 2NT<= invitation The SAYC Bidding System uses the bid of 3♣ or 3♦ not as pure sign-off but as an invitation bid with 7/8 hcp and a top honor with 6 cards. Opener Responder 1NT 3♣ <= invitation to 3NT pass <= only Hx or xxx or 15 hcp 3NT <= 16+ hcp and Hxx where Hx = Top Honor (A/K) 2 cards where Hxx = Top Honor (A/K) 3 cards Opener Responder 1NT 3♦ <= invitation to 3NT pass <= only Hx or xxx or minimum 3NT <= 16+ hcp and Hxx Responder’s hands possible: ♠10x ♥Jxx ♦xx ♣xAJ10xxx <= 3♣ ♠5x ♥Qxx ♦Jx ♣KJ9843 <= 3♣ ♠Qx ♥10xx ♦AJ10xxx ♣xx <= 3♦ ♠Q95 ♥943 ♦KQ109xx ♣x <= 3♦ How these transfers and invitation works in 2/1? First all in 2/1 advance partnerships reserve any response bid after 1NT opening to show 2 minors suits 5-4 or 5-5. Second, they don’t use response in 2NT as invitation to 3NT but as a specific transfer bid to 3♦ and use the 2♠ bids as a specific transfer to 3♣. Both transfers to minors use a pre-accept information from 1NT Opener saying good hand with Hxx support or bad hand without Hxx support. Opener Responder 1NT 2♠ <= transfer to 3♣ ? 3♣ <= I like this suit because I have 16+ hcp and ♣Hxx (♣Axx or ♣Kxx) 2NT <= I don’t like Opener Responder 1NT 2NT <= transfer to 3♦ ? 3♦ <= I like this suit because I have 16+ hcp and ♦Hxx (♦Axx or ♦Kxx) 3♣ <= I don’t like So, playing 2/1 to make invitation with 8/9 hcp Responder bids 2♣ and after bids 2NT. In this 2/1 propose we use after 1NT a response in level 3 to show a GF hand with both minors in distribution 5431 or 5521 and strength 10-14 hcp: Responder Opener …………….. 1NT ? 3♣ <= 3♠-1♥-5♦-4♣ or 3-1-4♦-5♣ 3♦ <= 3♥-1♠-5♦-4♣ or 3-1-4♦-5♣ 3♥ <= 2♠-1♥-5♦-5♣ 3♠ <= 1♠-2♥-5♦-5♣ ------------------------------- Bottom Line: Comparing SAYC and 2/1 we observe that the information about strength of Opener and Responder hands, in 2/1 are easier and clearer, and this allow partnership to have more space to interchange information about suits control (Ace/King/singleton/void) when slam is possible.
