Competition Problems 150
"Variations On a Theme"

composed by F.Y. Sing
presented for solving in August, 2017

In each of the following six problems South is to make five spades.  In each case declarer has just nine obvious tricks: five in spades, the A and K, the A and the A.  Each problem involves an elimination and throw-in on West followed by a red suit squeeze on East, but there are subtle variations in both the preparatory play and the ending.
