The Gambling 3NT is an opening 3NT bid showing a solid 6-8 card minor suit. It typically denies a void or 4+ card side suit.
Side suit strength depends on partnership style.
Opener may have anywhere from 0-3 outside suits stopped. Let us call these the aggressive, moderate and conservative approaches.
The aggressive style is more preemptive by definition. With the example hand above,
it's clearly more obstructive to open 3NT instead of 3.
This hand type is also more common than the conservative hand with a running minor suit AND
all side suits stopped, which appears about as often as Halley's Comet.
However, the disadvantage of an aggressive approach is that it may wrong-side the contract when
partner holds stoppers (tenaces) in the side suits.
There are several flavors of responses to play. Below is a summary of some common approaches.
There are multiple ways to define opener's rebids.
- In response to a strong 4 ask, opener may:
The same rules can apply over a strong 4 response, except that opener cannot use Gerber.
- Bid 4 Gerber.
- Bid 4/ to show a side-suit ace.
- Bid 4NT with a minimum.
- Alternatively, opener's rebids may describe suit length. In response to a strong 4 ask, opener can:
The same rules apply when replying to a strong 4 inquiry, except that opener must bid 5 instead of 4 to show long clubs with a stiff diamond.
- Bid 4// to show a singleton in that suit.
- Bid 4NT with a semi-balanced hand, i.e. 2-2-2-7 or 2-2-7-2.
- Bid 5 to show long diamonds with a singleton club.
- If the opponents double 3NT for penalty (how unsporting!), responder may bid 4 as a runout bid, asking
opener to pass or correct to 4.
- If the opponents overcall, a 4NT bid by responder is natural. It is neither quantitative nor Blackwood.
