Some strange things have happened here on the auction and one strange thing on the play so far. They have 10 diamonds, and yet south didn't raise preemptively over the double. North did a lot of bidding opposite a passing partner. North will have longer diamonds than hearts. North will also need at least one spade if we are going to make.
So north will be something like 1-4-5-3, 1-5-6-1, 1-5-7-0, 1-4-7-1, 2-4-5-2, 2-4-6-1, 3-4-5-1, 3-4-6-0. We can eliminate north as 1-4-5-3 against any opponent intermediate or higher, because if they were going to bid again over 1♠ with that, they would have doubled (takeout) instead of bidding an anemic four card heart suit.
If south had five diamonds (north 1-4-5-3, 2-4-5-2, 3-4-5-1) it seems he would have raised diamonds over the double. So our chances for a club-heart squeeze or a heart endplay for forced club lead from north away from the queen are somewhat unlikely (or unnecessary as club queen would not be guarded), as it only matters when north is the unlikely 1-4-5-3. You maybe able to throw SOUTH in with a club after ruffing last diamond and cashing 2nd heart for an endplay resulting in a ruff and sluff on a forced minor suit return.
What was the strange play? North shifted to a low heart. So he does not have a high honor sequence ♥QJ9x(x) or ♥JT9X(X)... etc. So south for at least the queen or the jack of hearts (we will see which one when we play small from dummy). The heart six is also the smallest outstanding heart, which hints at the possibility that north has four only hearts (or five if they would lead 3/5th in this position). We also note the ♦2 play by south at trick one. Could this be count (five or three diamonds) or s/p (I have something in clubs behind the AK)? The lack of a club shift and the dangerous (in theory) heart from only one of the two top honors suggest it was not s/p but rather count.
Before we choose a line of play, we win the ♥KING in hand (assume south played heart, the queen would be more informative than the jack -- just in case north is tricky and played ♥6 with 0-6-7-0, cover with the heart seven), and play a spade up to dummy and if west plays a low spade, finesse. If north plays an honor, win the ace. Did south follow to the first spade? The spade play will eliminate some of the possible hands for north. For instance, if both follow to spades, north can not have three spades, so two of the possible distributions are gone. When you play a second spade, you will find out if north had one spade or two spades. Eliminating more hands.
Let's make a couple of assumptions here before we commit to one line or the other (we will unblock high spades in east). If south showed up with the ♥Q and ♠K we surely will have to play north for the ♣Q (SOUTH would have enough to raise diamonds for sure with ♠K, ♥Q, and ♣Q, AND north would not have enough to open without all three of these cards). If south shows up with the ♠K and ♥J, I would also assume north has to have the ♣Queen. If south shows up with ♠Q, and ♥Q it would be closer. It is at least possible south might also have the ♣Q, but that is not as certain. If south shows up with ♥J and ♠Q, or no ♠ honor, the location of the ♣Q is still a question.
So option one. If north has 3 spades, we are going to endplay south in the minors (lose a spade, ruff a diamond, cash 2nd heart play three rounds of clubs from the top.
So option two. North has any two spades, we play north to be 2-4-5-2 or 2-4-6-1 or 2-5-6-0, and go with the same club endplay on south with a club throwin.
So the problem hand is option three, where north has just one spade, what honor did south have? (I DON'T believe south can have ♠KQ and a heart honor so if north has only one spade, it is an honor and we throw south in on the next round of spades). If it was the spade king we surely play north for the club queen. WHAT DOES SOUTH return. IF a diamond, that will help us eliminate diamonds for potential endplays. If a heart, that gives us a good count on the hand (north surely 1-4-6-2 or 1-4-7-1, or against weak opponents, maybe 1-4-5-3) if a club we play low in our hand and win in dummy. Did north play the ♣queen?
Against normal players, the line would be to cross to hand, ruff last diamond, cash heart Ace, cash club AK, EXIT a club to south -- who is out of spades, out of hearts and must be give you a ruff and sluff. This has to work because north can not be 1-4-5-3. Against weaker opponents where north could be 1-4-5-3 hand, the play is harder. So you are in a guess position. Let's look at how you might try to make a decision on the line suggested in above replies to squeeze, endplay north, or the line I am favoring of endplaying south. On club back by south, win in dummy, spade to west, ruff diamond (high). WHAT did south discard when you played a spade to west. If NS are weak players where you think north could be 1-4-5-3 AND if the cards played to date suggest that north has to have the ♣queen (see above discussion), and if south threw a diamond on the ♠ to your hand (which he would not do with 2-2-3-6 or 2-2-4-5 assuming again weak players), you might change your mind and duck a heart going for a heart-club squeeze on north (they can not knock out both your ♥ and last ♣ entry when they win a heart).
