Unofficial World Championship Checker Problem Composing Contest 35 - Double Jeopardy Strokes - September 17 - October 31, 2017

It is hard to compose short, tricky, multiple strokes in a single problem. Here are four original, unpublished, semi-lightweight examples. At one or more points in each solution, White offers Red a choice of jumping either of two different pieces. That's double jeopardy. The different jumps lose by different strokes. The challenge to solvers is to find both strokes.

Each setting has a total of 11 to 13 pieces; all Trunk solutions are pure strokes culminating with the 3rd star move. Just start giving away pieces. Duck soup for seasoned solvers, right?

Everyone is encouraged to solve these problems. Doing so may change your perspective on their quality. Check your solutions against the animated ones. Only the Trunk lines are animated; so don't overlook the notes describing the alternate strokes. Finally, please vote for the problem you think is best.

If you want to climb the Evaluator Ladder, tell Bill Salot which problem got your vote. His e-mail address is below the diagrams. Currently Liam Stephens is at the top of the ladder with two winners picked in two tries.
