North and South grasped at some straws on the way to 6D. South's bidding diamonds and then clubs and then diamonds showed a good 6-4 hand. With a bad 6-4 hand South would bid diamonds twice and then bid clubs. At the end South took a bit of a shot and was rewarded with a good dummy. The defense led the queen of hearts and a heart to East's king. South ruffed and noted that the slam was a good one. If trumps are 2-2, it is cold. So naturally they were 3-1, with East having three of them. This leaves South with a little club to worry about. Question: Having played two rounds of trump and seeing that East still has one, how should South continue to avoid a club loser?
