Match Play. Red leads 4-0 to 9. How should Red play 11?
Clearly two aces will be played 8/7(2). The clue to playing the other two aces is to look at White’s structure and count the number of checkers he has in the zone.
White has a blitzing structure and has twelve checkers in the zone. Both facts argue for not splitting the rear checkers and instead playing 24/23(2).
In fact, any play other than 24/23(2), 8/7(2) is a huge blunder.
