2 Major

   

All 4 of the following requirements for any 2 Major opening must be present:
a) 15+ DP guideline only, but the acid test is a strict 4-5 LTC.
b) No 5+-5+. distributions - these hands are NOT to be opened with 2Ma nor with 2
c) Distribution: 5+ card major & a 4 card side suit OR a 6+ Card Major  
d) 5431 always preferred to 5422 which often risks a further loser - Therefore with a minimum 5LTC & 5422 distribution consider opening 1 of the 5 card suit and rebidding in the 4 card suit.
e) A 5 card Major should be headed  by at least a top honour: A or K -. If not: downgrade & open 1Ma. 
f) A 6+ card Major and no 2nd suit  requires a minimum of 2 top honours: 2 of AKQ..

Note: In cases of strong 5-5's (<= 5LTC). In openings prefer 3  or 3 or 2 openings.

These 2Ma bids are structural in the system introduced as part of the requirements for dropping the concept of reverse. Essentially they reduce the top end of a 1Ma opening to about   15(16)HCP - giving a usual maximum  range of 10-16 for 1Ma opening.

Note 1: These openings are non-forcing. Always alert as 'strong non-forcing'
Note 2: The first rebid by opener (except when partner makes a raise) distinquishes 2-suited 5+-4+ (rebid 2nd suit) and from 6+ hands rebid your Major..
Note 3: In the sequence 2-2♠ natural opener must show a 4 card spade fit else rebid as if partner had responded 2NT.
Note 4: 2 & 2NT responses are both Forcing & Inquiries to explore opener's distribution - promising hand to be playable in at least 3 of partner's major.

Responder's bids:
Opener's rebids following: 2 or 2NT Forcing responses:
Responder's rebids:
Opener's 2nd rebid clarifies distribution or initiates cue-bidding:
Further bidding by either partner:
Ex1: 2-2N-3-4-4 - a cue bid
Ex2: 2-2-4 agrees either Spades and shows a control cue-bid
Ex3: 2-2N-3mi-3|4 to play OR 4|5 mi to play OR any new suit a cue-bid indicates undeclared support for one of opener's suits. TURBO follows...
