Opening Major:

- Must have 5 card and must have 12~21 HCP  
- [BROMAD](https://bridgebum.com/bromad.php):
    * redouble denies 3 card support (10+ pts) 
    * 2♣ - 8-9 dummy points 3 card support
    * 2♦ - 10-12 3 card support 
    * 1 level raise preemptive (weak) 
    * jump raise 4 card support
- In general, a splinter bid is a jump in a new suit, shows shortness with support in partner’s bid suit, promises four trumps, and is forcing; suggesting a slam.

Opening No Trump: △

- you must have balance card with only one doubleton. 
- No 5 card major
- 15-17 HCP for 1N
- 19-21 HCP for 2N 
- stayman applies with no interference  
- weak 1N is great for defence [weak1n (http://www.bridgesights.com/hondobridge/WeakNTPart1.pdf)

Opening with weak hand: △

- if you are one of the first 2 caller. dont call 2 with good hand. 
- open 2 of a suit other than clubs with 7~11 points with 6 card of the suit. only applies for first 2 caller. 
- Prefered to have 2 of 5 top card apply judgement. 
- For third / 4th hand when partner passed then need high points to call 2 of a suit

General Notes: △

- redouble denies 3 card support
- When defending at no trump NEVER lead your partner’s bid suit if you only have a singleton in his/her suit!!
- Never Put Down an 8-Card Suit in Dummy
- Never open a balanced 11 point hand

how to lead

jack denies top card/ T9 indicates having higher card
AJT5 - lead T KT94 - lead 9 lead J denies any top card.

point calculation

double

reverse

- **reverse: ** skipping the second bid and go beyond 1♣-1X-2X, 1♦-1X-2♥♠, 1♥-1X-2♠
- it requires a strong imbalance hand.  
- it is a forcing call.  
- very useful to notify partner about the strength. 
- jump raise partners first/second suite. 
- respond to 3N with 3rd suite block. 
- [reverse bids](https://bridgebum.com/reverse_bids.php)

drury

- partner calls major after a pass 
- 2♣ -> 3 card support with 10~ pts

defence of 1 level call: cue bidding / unusal 2N

- no min point requires
- typically good for weak / very strong. 
- [cue biding](https://bridgebum.com/michaels_cuebid.php)  
- [2N](https://bridgebum.com/unusual_2nt.php)  
- [ls/gs](https://www.bridgewebs.com/alton/Cue%20Bidding.pdf)  
- must not pass
- for 2N over call with 20+ points call double first and then 2N.
