SUPPLEMENTARY DETAILS [2]
2.1 2♣ followed by 3-either-minor shows a weak hand with a 4-card major and a 6-card minor, and is to play.
2.2 2NT/3-major shows 4-card support, 7-loser/8-loser respectively. Over 2NT, responder may re-transfer, trial bid, splinter, etc.
2.3 Bid shows suit bid plus next higher suit, min 4-4. Pass forces redouble, which is either passed, or 2-suit shows that suit plus higher, non-touching suit.
Redouble is relay to 2♣ for pass or correct
2.4 After our 1NT is overcalled, 2NT from responder asks opener to relay to 3♣, then all bids are relatively weak. Cue-bids are Staymanic. Cue-bids and 3NT deny stop if preceded by 2NT. Direct 3-level suit bids are forcing. 3-level suit bids preceded by 2NT are to play, but invitational if suit could have been bid at 2-level. Double shows values for 2NT with at least Hxx in overcaller's  explicit or inferred suit. 2-level cue bid is 2NT without stop.
 2.5 Ogust 2NT over 2♥/2♠  3♣/3♦ = min HCP;  poor/good suit ['good' = 2 of top 3]
3♥/3♠ = max HCP;  poor/good suit. 3NT=AKQ of suit.
2.6 3♣ asks for 5-card major [3NT rebid shows 5 hearts]. 3♦ rebid promises at least one 4-card major. If responder also has a 4-card major, he/she bids the other, or 4♣/♦ with both. 3♥ denies both 4- and 5-card major, 3NT shows five hearts.
Over responder's 3♦ transfer bid, 3♠ from opener shows two hearts and five spades.
