1NT - 1st & 2nd & 3rd (NV) Seat - 11-13 HCP - 3rd (Vul) & 4th Seat - 15-17 HCP

Five card majors are possible in all scenarios.

A reminder that you likely do not have the best hand to play so transfers and stayman don't make sense

When opening a 5 card major with this range it should be a rag suit if it is a good suit open the major instead

2♣ is a Modified Puppet Stayman promising invitational values (12-13/14-), but denying game forcing values.
2♦/♥/♠/3♣ shows a five card or longer suit (3♣ shows 6) and 0-11 HCP.
- if this is not passed can guarantee a 4-4-1-4 distribution with the 1 being in bid suit that is an honor
2NT is game forcing showing a balanced or semi-balanced hand, interest in a major suit game and 14+ HCP (similar to 2♦ Game Forcing Stayman).
3♦ shows interest in a club or diamond slam should be very long in one suit or 5-5
- 3♥ interest in club only no help in diamonds (doubleton)
- 3♠ interest in diamond only no help in clubs (doubleton maybe singleton with an honor)
- 3NT - min values
  All 4 level leaves a response allow Kickback RKC with the lower bid being clubs and higher diamonds
- 4♣ - 4/3 in clubs with w/ interest in slam
  - Should start at hearts for club kickback, diamonds bid is just setting the contract
- 4♦ - 4/3 in diamonds w/ interest in slam
  - Hearts is clubs again and spades is diamonds kickback
- 4♥ - 3/3 w/ interest in slam
- 4NT quantitative raise
3♥/♠ shows 5+ of that suit and an unbalanced hand. Game Forcing.
3NT, 4♥, 4♠, 6H, 6S, 6NT, 7NT are to play.
4♣ is Standard Gerber.
4NT invites 6NT.
5NT invites 7NT.

Even though this works against being doubled for consistency we will use DONT when doubled for penalty

*Note for this range a couple bids change 1c-1x-1NT is 18-19
