The Solution
South erred, as so often is the case, at trick one. South should let the king of spades win the first trick. The defenders won't be able to make the dummy ruff spades now and South will be able to ruff clubs in his hand AND set up the diamonds. South will make four hearts and may make five if the defenders err along the way.
Should South give up the chance at twelve tricks? That is a different question which you have to judge for yourself. Keeping in mind that West made a takeout double, there is a fair chance that hearts will divide poorly. The important thing about this hand is that South see and consider the possibility of letting West win trick one.
