West opens 1NT, your partner passes, you could make a takeout double with 12 points, some will, but others require 15-17 to double 1NT and will not. All Pass
Acol Bidding
West opens 1C, you make a takeout double "X", West rebids 1S your partner bids 2D. All Pass
Plan Before You Play
Opponents in 1NT; Plan your defense. Partner leads diamonds, then play clubs, letting the opponents lead hearts and spades
If you are in 2D/3D In count your winners: Spades: , Hearts: , Diamonds: , Clubs: .
The Play
The opposition in 1NT N/S should play diamonds and clubs and QS at every turn. How many light can you take them?
You in 2D/3D Draw trumps ASAP ruffing a losing heart in Dummy.
