Unlimited Games. How should Red play 54?
There is only one move here that is not an outright blunder.
22/13, running when behind must be wrong. 6/1, 5/1 leaves Red without a sensible game plan as both blitzing and priming will be difficult.
The correct play is the Double Tiger 13/4*. This gives Red blitzing and priming options and if a checker is hit it gives both back game and holding game options.
Once you see the play it is obvious. The problem is seeing it as a candidate play.
