2S

First obligation is to show a 4-card major. Plan to rebid 3C. Note the opening of 1NT on this semi-balanced hand. Even though no rebid problem, the honors in both short suits argue that 1NT is the better description.

1NT (12-14) - (DBL) - RDBL - (2C)

Double

Takeout, 3-card support for the other three suits. This agreement applies since responder's redouble created a force to 2S, and this is the first double by your side.
S J87
H K73
D K93
C AJ94

1NT (12-14) - (DBL) - RDBL - (2C)
DBL - (2D) - ?
Double

Penalty. By opener's double of 2C (showing a doubleton), he has at least 3 diamonds. This double is not takeout since it is not the first double by your side.
S KT84
H QJ76
D A95
C K5

1NT (12-14) - (2C) - ?
If 2C is natural, bid 2D (GF Stayman) or DBL (Stayman) depending on agreement in uncontested auction. This also applies if 2C is artificial.

But if 2C is artificial for the majors, there is no point seeking a fit with partner. Pass and plan to double once the opponents bid their major. But at unfavorable vulnerability, just bid 3NT rather than hoping for a large penalty.
S KQ984
H A52
D 6
C 9754

1NT (12-14) - (2C) - ?
Just ignore the 2C overcall (whether natural or artificial) and bid 2S (to play) if playing Two-Way Stayman or 2H (transfer) if playing transfer responses.

S 53

D A965
C KT97

1NT (12-14) - (2H transfer) - ?

C Q92

1NT (12-14) - (2D majors) - ?
Double (or 3NT at unfavorable vulnerability?)

D 432
C 32

1NT (12-14) - (2D majors) - ?
Double

Shows 10+ points and ability to double at least one of the possible suits. You intend to double either 2H or 2S. If opponents try a minor, opener will probably be able to double knowing that you have some values.

Natural with slam interest. Tends to show a distributional hand. If opener bids 4H, cuebid 5C. 4C or 4D by opener is an advanced cuebid in support of spades, over which you can cuebid 4H or just bid 4NT RKCB.
