Bidding after takeout double takes place according to Rubensohl scheme if the first opponent opened weak 2♣/2♦/2♥/2♠, the partner doubled and the second opponent passed.

Answers as far as possible:

• • 2♦/2♥/2♠ - any remaining available 2 level bids are natural and to play;

• 3 bellow the opponent suit - 13+ HCP, forcing;

  • • if the opponent suit is major - the other major four;

    • else - at least one major,

• • 2NT/3♣/3♦/3♥:

    • • respectively 4+♣/4+♦/4+♥/4+♠ if the suit is lower than the current suit - 0+ HCP;

      • else respectively 5+♣/5+♦/5+♥/5+♠ - 9+ HCP,

  • 3♠ - no majors, no stopper, 13+ HCP.
