Q

What is required for a weak jump overcall?

A

bidding 1 or more levels than is necessary - it is similar to a preemptive opening bid. It shows a weak hand with a long suit. The advantage is that it takes up bidding room which makes it more challenging for for opponents to find their best contract. The hand should be worth 5 or 6 playing tricks.

Q

What are the 2 reasons that responder would raise the preemptive opening bid when the responder has 3 card or longer support?

A
  1. rthe responder may have enough strength that the partnership can likely make a game contract
  2. the responder might want to raise to make it more challenging for the opponents to reach their best contract
20
Q

When a responder to a preemptive opening wants to bid a new suit what should the responder know?

A

responder will have a good 6 card or longer suit

if the new suit bid is below game, it is forcing even in competition. opener must bid again.

responder can make a signoff bid in another suit by bidding game in another suit

21
Q

What are the requirements for a weak 2 level preemptive opening bid?

A

2D, 2H, 2S

  • 6 card suit - usually 2 of top 3 or 3 of top 5 cards in the suit
  • 5 - 11 HCP - less than the values for an opening bid at the one level
22
Q

What is the special meaning of a 2 NT response to an opening 2 level preemptive opening bid (a weak 2 bid)

A

it has a conventional meaning

it is used only when responder can imagine a game if opener has a ‘good’ weak 2 bid

with a minimum weak 2 bid of about 5-8 points opener simply rebids at the 3 level

with more than a minimum, opener can bid a new suit to show a feature in that suit (an ace or king), or bid 3 NT with a solid suit but no outside feature

23
Q

what are the requirements for a 3 level preemptive opening

A

a good 7 card suit

less than the values for an opening bid at the one level

24
Q

What should you consider when responding to a preempive opening?

A

focus on trick taking potential of the combined hands instead of the HCPs

pass with no fit for opener’s suit and little prospect of making game contract

25
Q

What are responder’s action after an overcall?

A
  • Make the same that would have been made without the overcall, if that is possible
  • Make a suitable alternative response if the overcall has impacted responder’s original choice
  • Use the new options available after the overcall
  1. make a preemptive jump raise of opener’s suit with 4 card or longer support and a weak hand (6 - 9 points) 4 card support jump to 3 level; 5 car support jump to game level
  2. Use the cue bid to show support for opener’s suit (3 cards or more) and at least invitational strength (11+).
  3. Use the negative double to show support (4 card) for the 2 unbid suits and enough strength to compete (at 1 or 2 level 6+ points; 3 level 9+ points; 4 level 11+ points)
  4. Change suits with 5+ cards and 11+ HCP
26
Q

What are responder’s actions after a takeout double?

A
  • Redouble with 10 or more HCPs
  • make a preemptive jump raise of opener’s suit with 4 card or longer support and a weak hand (fewer than 10 points, if he had 10 or more points he would have redoubled)
  • Bid a new suit at the 2 level with fewer than 10 points. A new suit response at the 2 level is not forcing after a takeout double.
27
Q

When is a double for penalty?

A
  • a double of an opponent’s opening 1 NT or 2 NT bid
  • a double at the game level or higher
28
Q

What is Michaels Cuebid?

A
  1. Over an opponent’s minor opening, a cuebid shows both majors. For example, 1♣ – 2♣ shows hearts and spades.
  2. Over an opponent’s major opening, a cuebid shows the other major and a minor suit (at least 5 cards). For example, 1♠ – 2♠ shows hearts and either clubs or diamonds. Partner can make a 2NT relay bid to request partner to bid his minor suit.

With less than eight points, Michaels is not recommended - the chances of winning the auction are small and gives the opponents too much information. Bidders expecting to make or sacrifice can use basic Michaels at all point ranges with eight or more.

30
Q

how high do you play negative doubles?

A

through 4 H

31
Q

what determines minimum strength responder needs to make a negative double?

A

it depends on the level that the opener will be forced to bid. 6 pts at 1 or 2 level; 9 pts. at 3 level; 11 pts. at 4 level

32
Q

what is the right distribution for a negative double?

A

ideally responder has at least 4 cards in each unbid suit

33
Q

for negative doubles are there exceptions to having at least 4 cards in each unbid suit?

A

responder can usually get away without support for an unbid minor, it is dangerous to mislead opener about major suit length

34
Q

using negative doubles, what should you bid with 4 Spades and what with 5 or more Spades?

A

with 4 Spades bid double (negative) and with 5 or more Spades bid 1S

35
Q

what are the 2 situations which you should consider raising the preemptive bidder’s suit to game.

A
  1. when partnership is likely to be able to make a game contract
  2. when you have support for opener’s suit but have a weak hand and it is likely the opponents can make at least a game contract
36
Q

What should you consider when responding to a preempive opening bid when you are unsure how high and where the partnership belongs?

A
  • bid a new suit (forcing) to see if opener can support
  • bid 2NT after a weak 2 bid to ask for more information
37
Q

When partner opens 1 of a suit and the player on the right of the responder overcalls, the overcall has taken away some of our bidding room, but we have 3 new options. What are they?

A
  1. passing with 6 or more points
  2. cuebidding the opponent’s suit
  3. doubling (negative)
38
Q

why would we pass with 6 or more points after right hand opponent overcalled

A

partner is going to get another opportunity to bid even if we pass.

39
Q

what does a responder’s cuebid show?

A

shows a fit for opener’s suit and invitational (10+) or better values. A cubid replaces the limit raise

40
Q

what is the impact of the cuebid?

A

After an opponent’s overcall, a jump raise of opener’s suit is weak (preemptive) and a bid of 2NT is natural and invitational (10-12 pts)

41
Q

how do you advance a simple overcall?

A
  1. single raise - similar to responder - 3 card or longer support and 6-9 points
  2. preemptive jump raise - fewer than 10 points when partner overcalls at the 1 level - jump to 3 level with 4 card support; jump to 4 level with 5 card support
  3. a cuebid is forcing for 1 round - 3 card or longer support and 10 or more points
  4. a new suit is non-forcing (invitational)
42
Q

when you are bidding preemptively, what is considered a good suit?

A

2 of top 3 cards or 3 of top 5 cards

43
Q
