2N opening | 20-21hcp balanced (may have 5cd major), full writeup of 2N responses. Use Puppet Stayman to respond. | ||||||
Major openings | partial writeup of 1 of major responses Modified Jacoby 2N, Splinters 2-over-1 partial writeup, 2over1 agreement with Nick Raising with 3-card support (article by Dave Vidaver) |
||||||
Minor openings | Minor opening / major response scenarios Minor opening / non-major response scenarios Inverted minor raise shows 4-cd support, opening hand, denies 4-cd major. [With Scott, I play it this way] Criss-cross (jump-shift into other minor shows limit-raise) |
||||||
Checkback 2N (aka Spiral) | Responder inquires about strength of support in 1m-1M-2M sequence. See Minor opening / major response scenarios | ||||||
Fourth suit forcing | Bidding 4th suit - game-forcing, asks partner to describe hand (in priority order):
|
||||||
Reverse Drury | Over 3rd/4th seat major-suit opener, 2 asks if it's a full opener. Promises
3+ card support w/ 10+ hcp. Opener then responds
1. if responder holds long club suit they bid 2, then 3 over any bid by opener. 2. Drury is OFF over any interference. |
||||||
Help-suit game try |
When opener's 1-of-major opening is raised to 2, bidding another suit is the help-suit game try. It asks partner if he can "help" in that suit. Maybe you have a half-stopper, or Axxx, or whatever. It's a mechanism like splinters, for finding games (or even slams) with less than the normal 26 (or 32) HCP. This could be used over a limit raise, if you are slamming? |
||||||
Responding to 2 opener "waiting" | 2=At least 1 King; 2=bust; opener shows hand, then bid on. Better to use "control showing" responses. | ||||||
Responding to 2 |
Puppet Stayman may be ON or may be OFF. !! Discuss with your partner !! All other NT systems are ON. |
Weak 2s | 6-card suit, usually a major. 5-10hcp normal range. Standard treatment - vulnerable should have 2 of top 3 honors. Experts disagree... |
---|---|
Feature ask (over weak 2s) | Basic method for responder to find out strength of partner's weak 2 bid. With good hand, opener bids a "feature" -- usually a short suit, or suit with an honor. With a lousy hand, opener rebids their suit. |

Michaels cue bid | Showing 5-5 distribution; most of hcp should be in these suits Over a major, shows other major & unspecified minor. 2 Over a minor, shows BOTH majors. Normally, hand is weak or strong. With intermediate hand, make an overcall instead. Advancer makes minimum response with weak hand, otherwise jumps or cuebids. |

Cappelletti (Hamilton) | Common 1N interference bid:
|
||||||||||||
Responsive double | Response to a takeout
double or overcall, when opponents have bid & raised
their suit. 1M - X - 2M - X is responsive double, scattered values, 4 cards in the other major and no long suits (because you would bid a 5-cd suit if you had it!). When you double over partner's overcall (e.g., 1H - 1S - 2H - X), you should also be able to tolerate partner bidding their suit again (IOW, have 2+ cards in that suit.) 6-8 hcp at 2-level; 9+ hcp at 3-level NOTE: if opponents have bid & raised a minor, the responsive double promises 4-4 in the majors. |
Interference over 2 | Control responses are OFF; |

Unusual vs. Unusual (method 1) | Mechanism for handling Michaels or Unusual NT interference (most common version I play):
| ||||||||||||
Support double / redouble | Over interference following 1x - any - 1M - any, double shows 3-cd support.
Ex: 1 - Support redouble used over takeout-double interference. Ex: 1 - We play no upper limit on this type of double. NOTE: many players set the limit at 2 or 2 |
||||||||||||
Maximal double | After 1M-2M sequence, over inteference where normal
invites are not available, Examples: 1 - (2) - 2 - (3) - Also used when we are overcalling & opponents bid & raise in a lower suit: Example: (1) - 1 - (3) - |
||||||||||||
Four-suit transfers (used when opponents double 1N for penalties) |
|||||||||||||
Jordan | 2N following takeout double of partner's opener, shows good support with 10+ hcp. |
Lavinthal discards | First discard against NT is suit you don't want led. Size of spot indicates suit preference.
Preserves suit length in your good suit. Not recommended against suit contracts as you often want to discard in a short suit to increase ruffing chances. |
---|---|
Ace is led, singleton on board | Against suit contracts, show suit preference. |
Upside-down attitude (standard count) | When giving attitude only, reverse the standard convention.
I.e., attitude: high card discourages, low card encourages. For count, use the standard echo: high-low means even count. |
