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.
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.
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:
The bidding goes as shown. What is North's Second bid? Open South's hand and complete the bidding in the hand Above.
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
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
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.
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.
Rebids by Responder after a minimum 2 level reponse by Opener to forcing NT:
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
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
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.
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
