Two expert declarers in the Premier League reached 6
on this hand, but both went off on the lead of
4. South's
K won the first trick, and they switched to
Q.
First, some thoughts on the opening lead. The auction has been informative: declarer has five spades, three diamonds, the ace of clubs, the ace or king of spades, probably with the jack, and not much more. Dummy has five diamonds to the ace and king, four hearts to the ace, three spades to the ace or king and the queen, and a club. If that's all they've got, a heart lead will beat the contract by setting up a heart trick before declarer concedes a diamond, so long as declarer has two or three hearts. A trump or club lead may beat it too (the latter depends on who's got the spade ten), but only if declarer's got three clubs.
Making dummy a bit stronger: the contract is almost always making if dummy's got
K (unless diamonds are 4-1). But if instead dummy's got
K or declarer has
Q, a heart still succeeds. And the heart usually wins if dummy's got
Q with the king over it.
So, unless diamonds are 4-1, the heart lead is indicated from most holdings, and not much can be deduced from it.
Now how do you play?

The lead doesn't tell us much about who's got the queen of hearts, and nor I think does the choice of spot card, but perhaps restricted choice favours North having it, and it's more convenient to play that way anyway. The plan is take a heart finesse and discard a diamond on a heart. For our twelfth trick, we can either ruff the diamonds good, which needs both pointed suits to break (we need the third round of spades to be a late entry to dummy), or simply ruff a club, which needs only the spades to break. The important thing in the latter line is not to make the expert-looking unblock of the jack of hearts at trick one. We win the king of clubs, play the king and queen of spades overtaking, and lead the jack of hearts. North can't afford to cover it, so we will still be in hand to ruff a club, ruff a heart back to hand, draw the last trump, and claim.
This plan will gives us some chance when spades are 4-1 too: if South discards on the second spade we can change tack (which is why we played high spades first). Simply draw all the trumps and lead the jack of hearts, hoping to find North with an original holding of Qxx.
At my team-mates' table, tbe world-class declarer unblocked at trick one, won the king of clubs at trick two, and played queen then nine of spades, planning to finesse in hearts then ruff the diamonds good. When South discarded on the second spade he had to concede one off.
