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

In this quiz, the opponents make a 1 overcall.  That means our partner opened either 1, 1 or 1.

Responder can Pass (and usually will with 0-6).

1NT= 6-10   balanced with spades stopped (and typically 2 if partner opened 1, 2 or 3 if partner opened 1/1).
2NT=11-12 balanced with spades stopped (and typically 2 if partner opened 1, 2 or 3 if partner opened 1/1).
3NT=13-15 balanced with spades stopped (and typically 2 if partner opened 1, 2 or 3 if partner opened 1/1).

Double = Negative (At least 6-7 points -- probably a little more since opener might have to rebid on the 2-level). Typically showing the unbid suits, but the focus is on hearts (if the opening bid was 1 or 1).

2-level raise = 6-10 in support (after 1, usually 5, after 1, usually 4, after 1, 3+).

2 = Limit raise or better in the suit partner opened (after 1, usually 5, after 1, usually 4, after 1, 3+).

2-of-a-new suit = 5+ cards, 10+HCP, forcing one round (but not GF)

Jump-raise should be preemptive, but make sure the partnership discusses this situation [for example: 1 (1) 3]
