With a 5+ card unbid suit (no major fit)

8-11 points	bid at lowest level	N
12+ points	jump in suit	F

With 3+ card trump support

8-11 points	raise to 3	N
12-13 points	raise to 4	I
14-16 points	raise to game	N

With a stopper in enemy suit

8-11 HCP	bid 2 NT	N
12-16 HCP	bid 3 NT	N

Suit must be 6+ cards if jump is at the 3 level, or 7+ cards (or a strong 6) at the 4 level or higher.

If unsure of the best contract you should cue-bid the enemy suit (forcing) to allow room to explore.

In the case of hearts this is game (nonforcing).

This is an easy one

Ignore the enemy bid and respond exactly as you would to a 1 NT opening bid.

With a 4+ card unbid suit

0-9 points	bid at lowest level	N

With a stopper in enemy suit

6-9 HCP	bid 1 NT	N

Rarely you may bid a 3 card suit. Do not pass the double except with 5+ strong cards in enemy suit.
