You are East, declarer in 3NT after an uncontested auction (if you prefer that west responded 1♥, that's fine, the contract and lead will be the same). Scoring is IMPs (multiple teams of eight event) and the lead is the 3♠ (2nd & 4th leads, If you try the ten at trick 1, North will play the queen).
What is your plan?
Part 2
You are now West on the same hands, declarer in 3NT after South has made a take-out double. North leads the ♠5 (South will play the Jack if you duck).
What is your plan? Is there any difference from the previous answer?
Part 3
Exactly the same hand and auction and opening lead as part 2. But now you are told that the take-out double "promises opening values, but doesn't promise club shortage and other suits are a minimum two-card length".
Does this additional information affect your plan?
