The Checker Maven

Saving the Game

In this month's lesson in our ongoing Checker School series, we learn a valuable lesson in saving the game; in other words, looking for a way to draw even when our position doesn't appear to have too many chances. Here's the position:

WHITE

BLACK
Black to Play and Draw

B:WK26,K24,K23:BK32,K25,21.

This situation, attributed to a J. Cornock, does indeed look tough for the Black side, who have little mobility and a very narrow choice of moves. Yet, one of them is good enough to save the draw. Can you find it?
