The Checker Maven

Checker School today brings us a problem that exhibits a certain form of symmetry; not the perfect symmetry of our photo, to be sure, but nevertheless an appealing geometric pattern. The position is credited to a Mr. Brooks, and looks like this.

Black to Play and Win

B:W13,11,K3:BK10,5,K2.

As it turns out, reflecting our theme of symmetry, Black has not one but two ways of winning. Can you find them both?

Reflect on this for a while, but if you can't mirror the winning thought process, a simple click on Read More will flip to the solution page, which contains the answer to the problem, a sample game, and detailed notes, all courtesy of Ben Boland.

Solution

The solution, game, and notes are all from Ben Boland's Famous Positions in the Game of Checkers.
