In this series of 7 Quizzes (this is the second) our partner opens on the one level and the opponents overcall or Double.

In this quiz, the opponents overcall with 1 (which obviously means, our partner opened 1).

Here are responder's options:

1NT=6-10 balanced, diamonds stopped, no 4-card major
2NT=11-12 balanced, diamonds stopped, no 4-card major (invitational)
3NT=13-15 balanced, diamonds stopped, no 4-card major

1=4+ hearts (as if it went 1 P 1)
1=4+ spades (as if it went 1 P 1)

Double (Negative) = 6+ points and guarantees at least 4-4 in the majors

2 (cuebid) = Limit Raise (or better) in clubs, no 4-card major (usually at least 5 clubs)

Other bids: Don't try them without partnership agreement (most likely agreement would be jumps are "weak").
