1 Lesson 20: Game Trial Bids Surendra Mehta July 2007

2 Surendra Mehta, July Introduction What are Game Trial Bids? This is a very useful convention to investigate game after partner supports your suit. Game Trail Bids are very different depending on whether partner has supported your bid in major or minor

3 Surendra Mehta, July Game Trial Bids in Major Suit (1) Requirements for opener: –At least four cards in one of the majors –Open one of the major –The opener should have 15 to 18 points Requirements for partner: –Partner supports with 2 of that major –Typical bidding scenario1H/2H

4 Surendra Mehta, July Game Trial Bids in Major Suit(2) Openers rebids: –12 – 14 points – pass ( = 23) –19 points – Bid four of major –15 – 18 points – Total count between 21 to 27; Trial Bid sets in

5 Surendra Mehta, July Game Trial Bids in Major Suit (3A) With 15 – 18 points, aim to see if you can bid to a game level But how???? First investigate to ensure that the team does not have a particularly weak suit The opener bids his/hers weak suit

6 Surendra Mehta, July Game Trial Bids in Major Suit (3B) The partner’s response will depend on the number of losers in the weak suit bid by the opener –0 or 1 loser, jump to 4 of major –With 2 losers, bid 3 of major with min (6 points), or 4 with max (9 points); with 7 and 8 points use your judgment. –With 3 losers, bid 3 of major regardless of suit

7 Surendra Mehta, July Game Trial Bids in Major Suit (4) North’s handBidding  Q 7 4 3NorthSouth A Q  A K Q 2  ???  10 North has 17 points. All he needs to know about partner’s hand is whether he can help in spades North bids 2 , to express an interest in game, but concerned about losing tricks in that suit. North has 3 losers in spades and wants to know whether partner can help in spades – does he have A, K, Q or singleton or doubleton?

8 Surendra Mehta, July Game Trial Bids in Major Suit (5) How to count losers in a suit: Count Ace, King or queen as a winner – everything else is a loser Only look at your top 3 cards This is the method used in the ‘Losing Trick Count’ scheme of hand evaluation. In the previous example, South jumps to 4 if he has 0 or 1 loser; with 2 losers South bids 3 with min and 4 with max; with 3 losers south bids 3, regardless of strength

9 Surendra Mehta, July Game Trial Bids in Major Suit (6A) Your (South) handBidding  A 3NorthSouth J   ?????  Q North bids 1. Your 2 response shows 6-9 points, so your 7 points are below average. North rebids 2 , what is your response?

10 Surendra Mehta, July Game Trial Bids in Major Suit (6B) Your (South) handBidding  A 3NorthSouth J   4  Q North bids 1. Your 2 response shows 6-9 points, so your 7 points are below average. In response to 2 , you only have 1 loser in that suit, so jump to 4. If partner had bid 3  or 3 , you would close on 3, as you have 3 losers in  and 3 losers in  and below average points.

11 Surendra Mehta, July Game Trial Bids in No Trump (1) You open one of a minor suit (  or  ) Your partner supports your minor suit bid by you (e.g. 1C/2C); what do you do next? Requirements for opener: –At least four cards in one of the minors –Open one of that minor –Partner supports with two of that minor –The opener should have 15+ points to try for a 3NT contract

12 Surendra Mehta, July Game Trial Bids in No Trump (2) Opener’s rebid 12 – 14 points – pass ( = 23) 15 – 19 points – Total count is between 21 to 28 Too low to go for 5 in minor suit so you want to investigate 3NT

13 Surendra Mehta, July Game Trial Bids in No Trump (3) Investigate to ensure that the team does not have a particularly weak suit, and have stoppers in all the suits After your partner has raised your minor suit, the opener makes a non-jump bid in a new suit, showing an interest in a final 3NT contract. (N.B. A jump bid in a new suit is a ‘shift jump’ and shows interest in slam) It shows strength in the suit bid and asks the partner to bid a suit in which he/she has strength (a good stopper). Also the bid in the new suit must be below 3NT and should be a lower ranking one when you have 2 or more strong suits

14 Surendra Mehta, July Game Trial Bids in No Trump (4A) North (you)BiddingSouth  10 8NorthSouth  K J 9 A 9 41  3  K J 4  K Q 10?????  3 2  A Q  K (15 pts)(11 pts) After South shows points with a 3  response, the partnership has a min of 25 pts – enough for a game in NT but not in minor What does North bid? 2c

15 Surendra Mehta, July Game Trial Bids in No Trump (4B) North (you)BiddingSouth  10 8NorthSouth  K J 9 A 9 41  3  K J 4  K Q 103  3NT  3 2  A Q 7 4 3Pass  K (15 pts)(11 pts) After South shows points with a 3  response, the partnership has a min of 25 pts – enough for a game in NT but not in minor North makes a game trial bid by bidding 3 , showing strength in diamonds. South has both majors covered and bids 3NT. With only 1 major, South will bid that suit and North will go 3NT if he covers the missing suit. 2c

16 Surendra Mehta, July Game Trial Bids in No Trump (5) NorthBiddingSouth  K Q 3NorthSouth  10 5 A J  2  Q 5 3  A K  3   Q  103NTPass  K Q 8 4 North has 17 points, and knows partner has 6-9 points, so the most likely game is 3NT, but only if the partner has control of Clubs. 2  bid shows a spade stopper, and partner can bid 3  to show control of clubs. Without club control, South would bid 3 . N.B. North’s bid of 2  is superior to 2 in this case. If North bid 2, South might have replied 2 , leaving North none-the wiser about Clubs. 2c

17 Surendra Mehta, July Alerts EBU alert rules say that neither form of game trial bids need to be alerted, as they both should show a suit with at least 3 cards in it (no matter how weak the suit).
