Partner's attitude is known and the deuce reveals 3 card length.

Declarer has a doubleton club and three or four spades.

Partner cannot own more than 3 HCP.

You should cash a second club and follow with the ace of diamonds.

Your side will not win more than one diamond trick unless partner owns the king.

If South holds four top hearts, he will discard a diamond from dummy, but worse if he owns five solid hearts, you will lose the ace of diamonds.

South scores ten tricks if you cash out but eleven if you fail to take the ace of diamonds.

Occasionally partner might hold the king of diamonds and you will defeat the game.
