The late Roy Little soundly defeated all challengers again. His Thumper drew 7 votes, which was more than all his challengers combined. It combined a unique Zugzwang with a flashy, deferred quadruple into a 2x2 finish. Slava Gorin (Russia), Don Myles, Kathy Wirthwein, and Wilma Wolverton voted for it.

Tied for 2nd, with 3 votes each, were Subtle Pursuit, which hid a counterintuitive a retreating Zugzwang, by Ed Atkinson, and Sir Prize, a kingless, deferred, 5-way Zugzwang, by Jim Loy.

Ugly Duckling, by Bill Salot, trailed and lived up to its name, becoming the 1st contest problem in 14 months to get 0 votes.

Contest 60 had 157 visitors, an increase, and 13 of them voted.

Contest 60 was originally introduced as follows.

When you have a choice of moves, and they all lose quickly, you are in Zugzwang. These four, original, unpublished, contest problems are well calculated to put the defender in that unfortunate situation. Which one impresses you most?
