1) Which card do you lead from ♥QJ1032?

2) Which card do you lead from ♥QJ932?

From a broken sequence where the 2 top cards are consecutive, lead the top of the sequence (the ♥9 is the 3rd card in this broken sequence)

With no 3 cards sequence (full or broken), lead the 4th best card if you have at least 1 honor in that suit.

Question Number 9 - 13:
Against NT, your partner overcalled 1♠, and you want to lead to his suit.

9) Which card do you lead from ♠QJ2?

If you have less than 4 cards but there's a sequence, you can lead the top of sequence from a sequence of 2 or more.

10) Which card do you lead from ♠Q82?

From 3+ cards headed with an honor, lead your LOWEST card. When you lead your lowest card, you promise an honor (but no sequence).

11) Which card do you lead from ♠1082?

12) Which card do you lead from ♠Q2?

From a doubleton, lead the high card 1st. High – low shows you have XX (doubleton).

13) Which card do you lead from ♠A82?

From 3+ cards headed with an honor, lead your LOWEST card. When you lead your lowest card, you promise an honor (but no sequence). You may lead under an Ace only when you defend against NT.

Note that this lead could be useful to capture a possible honor form declarer's hand: Say the declarer has ♠QXX. Partner will win the ♠K at trick 1 and continue with the ♠J, and your ♠A will capture declarer's ♠Q now or later. But if you lead the ♠A declarer will be able to win with the ♠Q later.
