South leads the K.
East to make 6 against any defense and distribution.
Although this one is not difficult, it is easy to go wrong at trick one. The winning play is to discard dummy's club, ruff high, then lead the 2. On a trump return, dummy's eight-spot provides an entry necessary to set up and enjoy a diamond trick, in case that suit should split 5-0; any other return permits a high crossruff.
