Unlimited Games. How should Red play 44?
Making the 4-pt is the wrong idea here because Red’s structure is currently very good for restraining White’s rear checkers. 21/13, 8/4(2) would give Red a very disjointed position.
The point Red really wants to make is his bar-point. Therefore, 21/5 is wrong because it takes a checker beyond where it wants to live. The correct play is 21/9, 13/9 keeping two active checkers for the crucial bar-point. 21/5 is a very bad error. Everything else other than 21/9, 13/9 is a blunder or worse.
