You won the lead in hand a played a heart to dummy's King (7♥-6♥-K♥-4♥) and then play a small heart from the table (♥2-♥3...)
Let's say you don't know your opponents (they're not that bad though), what would you play if:
1. ♣5 lead to the ♣Q and your ♣A.
2. High ♠ lead to the ♠9, ♠J and your ♠K.
3. RHO hadn't echo in the trump suit.
Also, do you have a rule on how to play 9 cards missing the Queen? What does it depend on?
