West played low, which would perhaps have been right if East had held the king.

There was a fair chance that if East held the king, he would either cover the jack or think about doing so.

However the finesse won and it was clear that West held the king.

He therefore led the club five, gambling that his partner held the king.

Now the heart jack was led, giving West a second chance to cover if he held the king.

If South held the king he would be unlikely to lead the suit from his hand.

He straightened his arms and held the king at their full length from him.

South led the heart jack, in the faint hope that West held the king and would cover.

It seemed likely he held the king and West the ace-queen.

But if the adversary himself hold the king, there is no penalty.
