Opening Lead C3, RHO discards a DIAMOND
Solution given below
You can quickly count your sure winners... 7C + 2D + 2S + 1H that is 12 tricks. You need 13. One way to win an extra trick is to play a heart from the dummy towards your AQ, playing the QUEEN if RHO plays small. This finessee is essential a 50-50 shot.
This hand is a simple percentage play problem. The "trick" is not to be in a rush to take the "obvious" heart finessee. A second place the extra trick can come from is the spade suit. Here all you need, if you manage your entries to North ok, and if the spade suit to split 3-3 or 4-2 you can set up a long spade. Even a 5-1 is ok if WEST has the singleton and it is the Club 8, Q, or J. There is almost an 84% chance the spade suit will divide 3-3 (35.5% ) or 4-2 (either way, 48.4% ), and there is an extra 3.6% chance that if the suit is 5-1, that west will have a singleton Q, J or 8. This come to about 87.6% you can gain an extra trick in SPADES by playing to ruff out their long stopper in that suit.
And if you play on spades FIRST, you will discover the spade situation in plenty of time so that if the suit does split poorly for you, you can still fall back on the heart finessee. So half the time when spades go wrong, the heart king will be with EAST and that will bail you out. So your chance of making this slam is 87.6% + 1/2 the time the suit split poorly (which occurs 12.4% of the time) or 87.6% + 6.2% = 93.8% (math of course, not exact). Do you need to be able to do this math... of course not, just remember, two chances are better than one and a 3-3 or 4-2 split is a suit is generallly much better chance of occuring than a king being onsides.
To take advantage of all these chances, win two clubs, cash SPADE ACE and SPADE. If both follow to two round of spades, ruff a spade, enter dummy with a trump, ruff a spade, cross to dummy in diamonds and throw your heart QUEEN away on good 13th spade.
If East shows out on second spade, you must take heart hook. If West shows out on second spade, but played Q, J or 8 on first round, lead a spade forcing EAST to cover, cross to dummy in clubs, and lead another spade forcing EAST to cover. Finally enter dummy with a diamond and throw the heart QUEEN away on the good Spade (East spade will be lower).
