Other agreements in leading, e.g. high-level contracts, partnership suits:
King requests unblock/count [against NT], count [against suit contract].
Lead of queen against NT may be from KQxxx and requests attitude. Strong 10 from AJ10 and KJ10
Ten not treated as an honour, so lead of 9 promises 10 or is singleton or doubleton.

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
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 suit/good suit [2 of top 3]
3♥/3♠ = max HCP;  poor suit/good suit [2 of top 3]. 3NT=AKQ of suit.
2.6 3♣ asks for 5-card major. 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. Applies over opening 2NT and over 2♣ followed by 2NT rebid. After 3♠ response, opener rebids 3NT with no slam interest or 4♣/♦ as Minorwood.
2.7 After 2♣ opener, suit rebid shows number of playing tricks, e.g. 2♥ shows 8, 3♥ shows 9, etc, and is N-F.
