Since you have two chances at spades, it is right to lead one even though declarer is prepared for the lead. Normally one would lead low from Ten third, but can this be right? Partner did not open a weak two, so the opponents are likely to hold five spades. The declarer is more likely to have the doubleton.

In fact, the winning lead is the spade ten. Dummy held Q 9 4 and declarer had K 8. The lead of a low spade, the choice at both tables, provides a double stopper. The more imaginative lead of the Ten beats the contract.

This is one to remember.
