- Double for Take-out (shortage in the opponent’s suit, opening values)
- Suit Overcalls: 10+ points & a 6-card suit (or good 5-card suit)
- 2NT Overcall: 16-19 points semi-balanced with a stop in the bid suit.
Responding to Take-Out-Double
- With 0-8 points make a simple response (lowest level).
- With 9-10 points make a jump response if you have room.
- With 11+ points go for game (in a major).
- Over 2♥ you have room for three bids in spades, 2♠, 3♠ or 4♠.
Whereas over 2♠ you have room for just two in hearts 3♥ or 4♥.
Thus the 9-10 range above is only used over a 2♥ opening. - Over a 2♠ opening your two ranges should be 0-9 weak response, 10+ go for a game
