Other Interventions

Overcalling One No-Trump

• A one no-trump overcall shows 15-18 high-card points with at least one but preferably two stops in the bid suit.
• Prefer to call 1NT if you are within range even if your hand is not a classic no-trump shape. It helps partner to know your strength.
• Agree to 'Systems On' responses.
• For stronger hands double first.

Takeout Doubles

• Normally opening strength with shortage in opponents' suit (can be slightly weaker if singleton or void in opponents suit).
• Very willing to support any of the other three suits (in particular any unbid major).
• May also be a very strong hand (too strong for any other action).
• Do not bid just because you have an opening hand. Suit and no-trump overcalls and doubles describe particular hands to your partner.

Responding to a Takeout Double

• You must respond unless you want to convert to a penalty double.
• Making a minimum bid does not show any points (0 to 8).
• With 9-11 jump.
• With 12+ points force. (Remember unassuming cue-bid.)
• A shapely hand can be considered stronger than just its high card point count.
