Bieden na interventie

After the opponents interfere on the 1-level

• Can you still do the bid you wanted to make before? Then do so
• Can you no longer bid the bid you wanted to make?
  • Double with 7+ points and you hold at least 7 cards combined in both unbid suits
  • Bid 1NT with 7-10 points and a stopper in the opponent's suit
• Bidding a new suit on the 2-level still promises 10+ points
• Sometimes you have 6+ points, but no suitable bid. Then it is ususally best to just pass and see what happens.

After interference on the 2-level

In general, the same rules above still apply

• Support your partner with a fit
• Bid a new suit on the 2 level with 10+ points and a 5+ card suit
• Double with 10+ points and at least 7 cards in both unbid suits
• Bid 2NT with 10-11 points and a stop in the opponents suit. Bid 3NT with 12+ and a stop in their suit.
