Any switch might work, but a club switch seems to require least from partner.

What are you playing partner for ? noting he didn't lead a diamond. Form of scoring and partner's preferences on leads may be important here.

I switch to a club (10), Kxx and enough to stop declarer running 9 is sufficient.

Some quick point counting first. You've got 9 and dummy has 9, which adds up to 18. Add in openers 15-17 and that leaves partner with 5-7.

don't have a future based on partner's lead. Also Q would seem to be in declarer's hand. Additionally, it would seem to imply partner probably doesn't have anything more promising in the suit, else it might have been led.

With length and honors, a lead might also have been made. Even if partner holds length and an honor, it's probably not be enough to allow developing tricks in the suit fast enough to defeat declarer. Conversely, if declarer has length, leading may assist declarer by attacking partner's vital stopper in that suit.

How can we defeat this contract?

seem like the most likely suit in which to develop tricks. So a 10 or 9 Depending on how you lead from Q109 combinations seems best.

Tc

Partner has 5-7 HCP with nothing in spades. We start with two spade tricks; how do we get three more?

Outside of clubs, we have nothing, and partner will be able to contribute at most two tricks (he has at most two red cards that will produce tricks). So if we're going to beat this hand, we have to take at least one, and more likely 2-3, club tricks.

So let's build our club trick(s). If partner has Ax(x) or Kxx, the Tc works quite nicely. Even Kx might work if declarer goes after red tricks before knocking out the other spade. And if partner has Jx or Jxx, along with the Qx of D and the Kh, that will work, too.

Cheers,
mike

The hand is a little different from expectation, but a club switch still wins.
This is kind of position I come across quite often playing Bird-Anthias leads which requires some practice but is quite workable.
