"Feature"

When partner opens a Weak Two bid, usually 2/2/2, "FEATURE" is a convention that asks partner to show an ACE or KING in a suit "outside" of the Weak Two suit.

* Many agree that a Weak Two bid requires 2 of the top 3 honours in the long suit.
Some allow for 3 of top five honours.
Some have no suit strength requirements.
With low/no suit strength requirements, showing a FEATURE also requires a hand of 8+ HCP.
A2 QJT876 32 543, a low standard weak two, would not rebid 3 (less than 8 HCP)
A2 KJT876 32 543 would rebid 3 (8+ HCP)
**If you adopt low suit standards, rebidding the weak suit does not necessarily deny all outside Aces/Kings.


A popular alternative to FEATURE is
OGUST

Where suit standards are low (e.g. A2 T98762 K2 543) OGUST may be preferred to feature

Ogust is a conventional 2N response to a weak two opening that asks for suit quality and hand strength:
Responses to 2N inquiry after any weak two bid:

3: shows "bad suit" and a "bad hand" Q2 QJ9876 32 543
3: shows a "good suit" and a "bad hand"
32 KQJT76 32 543
3: shows a "bad suit" and a "good hand"
A2 JT8762 KJ3 52
3: show a "good suit" and a "good hand" A2 KQJT76 32 543
3N: shows a solid suit 32 AKQJ76 32 543 

What constitutes a "good suit" or a "bad suit" depends on partnership standards. If any 6 card suit may be opened, two of the top three honours may constitute a "good suit".
A "good hand" depends on the acceptable point range for opening: within 2 points of the top of the range qualifies.
If playing 5 to 11, 9 or more points is acceptable.
With 9 or more points and KQxxxx or better in the suit, many opt for the 3 rebid.

Some reverse the meanings of 3 and 3. Some just confuse them. Let your partnership make its own choices.

OGUST 2N askers invite, either game or slam, with 2N, while simple raises can be pre-emptive.
