1 H/1 S Openings Lessons 25 to 36
 
 
  Major Suit Opening Bids

Lessons 25 - 36 will actually cover the 2/1 Game Force convention which only applies after Opening 1of a Major in the 1st or 2nd seat.

  Rebids by Responder after 1H 1S ? Play of the Hand

In this situation with no H support it is now Responder's responsibility to find the right game contract. 2 is artificial and forcing to game and checks for 3 card Spade support. 2and 2NT would be natural with invitational values. 2/1NT rebid; 3 over a minor rebid are GF as discussed in Lesson 27A.

Before Opening Opponents hand Plan to make 4 with 6 of club lead.

TRICKS REQUIRED: 10

WINNERS: 4,  2 , 2+  1 = 91/2 If Spades break normally and K of H's conceded

LOSERS: 1+   2 1= 4 from Declare's point of view.

PLAN: Tricks possible outside trump suit include 2 conceding K. 2 and 1. Need to make 5 trump tricks/establish additional diamonds. Win South Ten of clubs with A. Play heart to A then Q of Hearts discarding a club if West ducks. If West covers ruff. Spade to A play J of hearts discard a Club. In the actual hand E ruffs and plays Q of spade.

At this point there is a winning Trump out and you've lost one trick. In order to keep an entry into hand if the Diamonds can be established the best play now is small Diamond to the 9 in dummy. tricks lost will be 1Diamond and 2 Trumps.

  27A 1S Response to 1H; SPECIAL FEATURES

These Bridge Clinic Lessons follow the School of thought: "DONT look for a 2nd Major fit UNLESS going to game; Go to highest level when weak or invitational and showing support for Opener's major". Therefore 1/ 1 EITHER denies 3 card heart support OR is the Forcing to Game. With 3 card support, limit raise values and 4+Spades, Respond 1NT planning to bid 2 over opener's minimum (11- 15) response: So the following sequences apply when Responder holds 4+Spades:

  1. 5- 9 hcps & 3hearts: 2
  2. 10-12 hcps & 3hearts: 1NT. When Responder now bids Spades over Opener Rebid he is GUARANTYING 3 card support, limit raise values and 4+Spades.
  3. 5-12 hcps & 4+hearts: Use Bergen/Other raises that show 4card support
  4. 13+hcps GF 3+ card Support  bid 1 then show Heart support as follows:
    1. Over Opener's 1NT bid 2. thus the sequence 1 - 1  -1NT - 2 is a GF in Hearts 
    2. Over Opener,s rebid in another suit a jump in Hearts shows 3+ H's and 13+hcps
    3. Over Opener's support of Spades, Reponder may choose to take over or show slam interest 17+hcps by showing Heart support.
  5. GF Values and 2-hearts: 1 then use NMF style 2 over Opener's 1NT rebid to show 5 Spades, 4thSuit GF or Jump to game.

The bidding goes as shown. What is North's Second bid?  Open South's hand and complete the bidding in the hand Above.

BIDDING:

1: 5+ Hearts 11-21 hcps

1: 4+Spades & Either 0-2 Hearts 5 - 9 hcps or Game Force

1NT: 5Hearts 11-14 hcps NO singleton/Void

2: 5 Spades 10+ hcps

2: 5 Hearts 3 Spades 12-13 Total Points

4: Go to game Final Contract

  26 B. Opener's Rebids after a GF; Play of Final Contract

Rebids by Opener below 2NT show 11-14hcps and a rebid of the major does not promise a six card or longer suit. Bids 2NT up to 3 of the major show 13+hcps. A single jump shift show 4Card support for reponder and singleton/void in suit bid.  A jump to 3 of the major and bids beyond show 16+ hcps. 3NT is 18-19 balanced.

Therefore Opener show additional strenght by higher level bids. In contract Responder's policy is "Fast Arrival". That is after a minimum rebid by Opener a Jump to game shows a "minimum" Game Force, whereas slow rebids below game show additional strength.

BEFORE LOOKING AT OPPONENTS HAND PLAN TO MAKE 10TRICKS IN HEARTS WITH 6 of Spades Lead

TRICKS REQUIRED: 10

WINNERS: 1 + 5 + 1/2 + 3 = 91/2

LOSERS: 2 + 11/12 +  1/2= 4

Put up J of Spades and win covered honor with A. Finesse to set up a spade discard on 3rd club trick. Before pulling all trumps play up to K of Diamonds and plan to ruff a Diamond.

Actually make 1S+6H+1D+3C + 11 tricks

  26 A. 2/1 Game Force - General Principles

As Reiterated in previous Lessons, the 2/1 Game Force convention only applies after an Opening Bid of a Major in the 1st and 2nd Seat.In this hand when West opens 1, reponder immediately sees that he will force to game with 3card support and 13 hcps, and responds 2, from this point the partnership is obliged to contiue bidding up to th 4 Level. Obviously this would not be actually Game in a minor. So here again there is another exception in that this convention may not guarauntee game in a minor. Some players attempt to include this but this program advises against it since to get to a total of 28+ hcps necessary  to take 11 tricks reduces the effectiveness of the Convention widening the range of the 1NT forcing.

In this hand West Opens 1 and East Responds 2. Open West's hand and complete the bidding.

BIDDING:

1H: 11-21hcps, 5+ hearts

2C: 13+hcps 4+Clubs forcing to 4 Level Game

2H: 11-15hcps, 5+hearts. Re-bidding the Major at the 2 level shows a minimum hand and does not guarantee a 6 card suit.

4H: No extra Final contract.

  25 B. Rebids by Responder after using Forcing NT

 Rebids by Responder after a minimum 2 level reponse by Opener to forcing NT:

  1. 5 - bad10  hcps < 3 Hearts
    1. Pass with better fit in second suit; that is 4+Cards
    2. Return to Opener's Major with 2 Card support
    3. Bid new suit with 6+Cards. So that 1 - 1NT - 2 - 2 is a drop dead sequence showing a relatively weak hand with 6 diamonds.
  2. Good 10 - Bad 13 hcps < 3Hearts
    1. 2NT with stoppers in other 2 suits
    2. Raise Opener's 2nd suit with 4+card support
    3. Jump in 6 card suit
    4. Raise Opener's Rebid of 6C suit with 2 Card Support

The objective in 1 is to play in the best partial. 1NT is not an option once not a passed hand; but this is more often an advantage. 2 describes invitational bids which cannot be mis-interpreted as any thing else since the original 1NT response limited values to invitational strenght.

Before looking at Defender's Hands, Plan to make 10+ Tricks

TRICKS REQUIRED: 10

WINNERS: 3S + 2H + 2D + 2C = 9  

LOSERS: 2S + 1H + 1C

PLAN: Ruffing a Heart in dummy removes the heart loser and gains a trump trick for 10 tricks. Play for split honours in trumps by double finessing the Spades. This succeeds for 11 tricks 

  25.A Major Openings and the Forcing NT Response

North Opens 1. How would you bid this hand. You want to invite to game with 3 Card support. In 2/1 Game Force the 1NT response to a Major opened in the 1st or 2nd seat is forcing for 1 round showing 5 - 12 (even 13 if responder has 0-1 of Major opened). With 12-14 balanced Opener rebids the longer or lower minor. Responder jumps in the major to show invitational values (10 - 12) with 3 card support.

Open North's hand and complete the bidding.

Bidding:

1S: 11 - 21 hcps 5+ Spades

1NT: 5 - 13 hcps 0-3 Spades forcing

2C: 11 - 15 hcps 5+Spades and 2+Clubs. The only time Opener would have only 2 clubs is if his distribution is 4S. 5H. 2D 2C.otherwise the minor rebid is 3+

3S: 11 - 12 Total Points 3Card Support

4S: 14+ Total points Accepts Game Invitation
