Match Play. Red leads 4-2 to 11. How should Red play 42?
In positions like this one Red needs to maintain maximum flexibility to escape his rear checkers, anchoring with something like bar/21, 24/22 is the wrong idea despite the possibility of Whit rolling 22 or 33.
Having said that bar/23, 24/20 is better than bar/21, 22/20 because it lessens the impact of White’s double twos.
