Introduction of bidding method of Italian blue plum blossom

1c open call: 17 points+.

Call:

Enhanced display control (a=2, k= 1).

1d: 0-2 control, 0-6 points;

1h: 0-2 control, 6 points+,

1s: 3 control, and so on to a control whose 2d is 6,

2h/2s: Under 6 o'clock, the color of the call is 6 pieces and two big cards.

2 nt: 7 control.

After the other party scrambled to make a phone call, the called party didn't make a phone call equivalent to 1 level, but doubled it to level 2. All other calls are controlled and displayed, and 2h/2s keeps its original meaning.

After the opponent jumps and calls, the called party should not call: 0-6 points, double: 6 points+,should call suit: force a round, should call no general: 3-4 control, and call deduction: 5 control.

It should be called 1d followed by 1 nt and 1h followed by 2nt. It should be called something else: forcibly calling the bureau.

Tell people to jump and call: force them to call the office.

1d/ 1h/ 1s drive: 12- 16 points.

The natural restriction is called suit 4+ (1d can be 3).

Call:

Most of them are natural calls. Jump call: restrictive call. Jump should be 2nt: 1 1- 12, type 4333. Jump should be called a new color: solid color and semi-solid color long sleeves, 13 points+.

2 covers 1 Call: 2nt is mandatory, and the caller must call 5 sets more.

Jump should be called 4c/4d: it is agreed that the suit of the calling party is a general card, and the suit of the called party is controlled.

1nt: A: 13- 15 point moving average card, with long sleeve c, the height of two flowers is exactly 3/3. B: 16- 17 point average card.

Call:

2C: 8- 1 1 point, the caller calls 2s with B card, and the caller calls 2nt to ask Gao Hua.

2D: 12 o'clock+,enter the station to force the caller to call. Callers will call 2nt with type A card, and then call SiGaoHua with type B card. If there is no high flower, it is called 3c, and the caller will call 3d to ask for low color. After the caller calls 2nt, the caller should call 3c again, that is, the caller is required to indicate the card strength and number of C, and the caller answers with a four-level answer.

Jumping should be called 3 suits, which means that the suit called is 6 sets leading by two top cards, with 6-7 points.

The jump call is 4c/4d, and the transfer call is 4h/4s.

2c incoming calls: 12- 16, with more than 5 c's.

Call:

2d, protocol call, asking the caller to bring up the second episode. If the caller doesn't have a second suit, call 2nt again, which means that the other two suits are blocked, and call 3c again, which means that the other suit is blocked. At this time, to call the caller 3d again is to ask the caller that another suit is blocked.

The other two levels should be called both real and non-coercive.

2nt call: 22-24 points average card type, 5 weak and low sets.

3c open bid: closed open bid, which means at least 7 winning piers, one of which is outside the C set.
