This did not happen because of an odd development at the first trick.

A club was led to the eight at the second trick, and West won with the queen.

East should have played the club four at the first trick.

A better defense from East would have been a shift to the club king at the second trick.

When East returned the nine at the second trick he played low.

A better try is for South to lead a low heart at the second trick.

East was given the lead with a heart at the 10th trick and had to break the club suit.

East, however, had an awkward lead to make at the second trick.

The effect is the same if East throws a heart at the first trick.

The position was clear, so at the 11th trick South led a heart.
