23-level openings & responses:

2:near game force. Responses 4 steps show number of controls (Kings=1 & Aces=2) Steps: 0, 1|2, 3|4, 5+

3: 2-suited. Shows +|+ <7 LTC Forcing to agreement. Responses Select one of the indicated suits at 3-level or at 4-level with length. Bidding 3N is a forcing distibutional inquiry , which again can be reverted to one of the indicated suits. Finally a 4N inquiry for partners LTC, steps: 7,6,5,4,3. Do not underestimate power of 5-5 or better hands.

Suit openings of 3H or beyond are all pre-emptive.

Aspects opponents should note:

No additional point count requirement for simple 'reverses'. A 'high' reverse needs  more strength and is automatically forcing as is any NEW suit at the 3-level. If already bid naturally by responder  then a repeat is a STOP bid showing 6+ length and weak < 10HCP
1NT rebid 12-16 balanced with a 2C inquiry (requires 9 HCP) all other bids natural weak.
2NT rebid without jump 12-14 i.e after a 2over1 response - if stronger bid any new suit or 3N as appropriate.
2NT rebid with  jump is 17-18 balanced
Inverted minors are used even if RHO overcalls, but a Major suit is never hidden
Jump rebid by opener in a  new suit is short suit with top controls
1NT overcall is 'unusual': weak or strong with 4+ cards in lowest unbid real suit - available in both 2nd and protective positions.
4NT meaning depends on context - 6 possible meanings!
2 sequences use asking bids for trump support and controls in other suits - always in step responses.
