Q lead in a NT contract

PDF
King lead in a NT contract
Leading a K in a NT contract promises a very solid suit, with at least 4 cards... That's a "selfish" lead. Lead the K when you hold
  • KQJ97
  • KQ1096
  • AKJ10

When you hold :
KQ 3rd, or even 4th lead the Q to makes the difference with a K lead.
Leading Q is looking for a complement in your partner's hand...

Exercise 3695 Q . Your partner has around 10 HCP, most probably in the majors. Leading is a good idea. But the K would show a solid suit... The 5 would block the suit (K and Q would remain and communications would be impossible). Q is the only option.
 
 
Q lead in a NT contract
A Q lead shows 2 types of suit : with or without the K
  • A 3 cards sequence, most of the time in a 4 carder. Par example, lead Q with QJ10x, and with QJ9x (broken sequence), but lead 2 with QJ62 (that's actually not a sequence)
  • If you hold KQx, lead Q. A K lead would promise a minimum of 4 cards with 3 honors ! This happens in majors rather than in minors.

Exercise 3804 Q is the right choice. Top of a sequence takes priority over a 4th best card. The sequence is not perfect, but the 9 makes up for the 10. QJ108 would be a perfect sequence.
 
 
Your partner's choice
Your partner will give an attitude signal. Zia's advice is to play a low spot card to show interest. Doing so, you save an intermediate card which could be useful later on.But make sure you and your partner agree on the same signal system ....
