Unlimited Games. How should Red play 66?

A lesson in connectivity and duplication.

24/18, 21/9, 10/4 duplicates ones and sixes and keeps Red’s checkers nicely connected. Put the checkers where you want them, as the saying goes. Over the board, 21/9, 13/7(2) was played but that doesn’t meet the demands of the position and leaves the rear checker stranded.

Once you see the right play it is obvious. The problem is in seeing it as a candidate play.
