We get our title for today's Checker School installment from the look of the problem position.
BLACK
Black to Play and Draw
B:W28,27,K15,10:BK22,20,16,12.
Black's little "bump" of three men off on the left side of the board is a formation that spells trouble, because it has no mobility, and mobility is what checkers is all about. But this bump in the road, though it's kind of a rough one, won't cause a wreck--- if you know how to handle it. There's a draw here for Black; can you find it?
Don't let this problem bump you off; solve it and then give your mouse a bump on Read More to see the solution, a sample game, and complete notes.
