Lead a small ♣ to ♣A . East will show out. It is easy then then to finesse the ♣Q - Lead a ♣ If West plays the ♣10 , you play the ♣J  and the ♣Q falls on your ♣K . If West play ♣Q, you play ♣K and the ♣10 falls on your ♣J . If you start with ♣K then you will lose a trick to the ♣Q.

With the opponents trumps removed, play a small ♦ to ♦Q, then a small ♦ back to ♦A , followed by ♦K . North's fourth ♦ can now be ruffed in dummy. If you start with ♦A, followed by ♦K then ♦Q you will be in the wrong hand. In this instance all is not lost as you can get back to your hand by ruffing a spade. If you try to get back to North using a club then you won't have a trump left in dummy so will lose a trick to the ♦J.

On a diamond lead, there is a way for east to make all 13 tricks. East can count only 10 immediate winners (6 clubs, 2 diamonds and 2 spades) and so should be careful not just to play out all the top tricks (the defence will eventually win and then have winning diamonds). The goal is to make as many tricks as possible…. not just enough for game!
The best chance is to win the lead with ♦ K  and play the spades immediately. Start with the ♠ K  to avoid blocking the suit and then play the ♠ 9 towards ♠ AJ, planning to play the Jack so as to take a “finesse”. If the missing ♠ Q is in the south hand then the Jack will win the trick and then the Ace can take the Queen. East will now have 5 spade , 2 diamond and 6 club tricks, making all 13 without having to play the heart suit!
