Match Play Red leads 10-3 to 11 (post-Crawford). How should Red play 33?
The key to this problem is creating time for Red to continue to play his checkers safely. 20/14(2) creates too many potential problems for Red. Better is 20/17(2), 13/10(2). Hopefully then it will be White who will crack first.
20/14(2) is a small error.
