Crni sada definitivno igra backgame stoga plan bijeloga treba biti napraviti potpunu blokadu kako bi podijelio checkere crnoga u dva dijela i prislio ga eventualno da igra na duboka polja u svojoj kući čime bi umanjio svoju šansu da ikad ima snažan board. Nakon toga bijeli ne bi imao problema ući u igru u slučaju da završi na baru. Sada kada znamo plan igre lakše je pronaći potez koji je najprikladniji. Nakon očitoga 13/7, bijeli treba započeti 5.polje koje mu treba da dovrši blokadu. Crni nema boarda, ima slot u kući i samo 8 checkera za igrati s njima.

Black definitely plays backgame now so white's goal should be to make full prime in order to divide black's army into two pieces and probably forces him to bury some checkers deep in his board before he has to break his own. After that white will has no problem if black puts him on the bar because he will enter easily on his crunched board. When we know game plan it is easier to find appropriate move. After obvious 13/7, white should slot 5pt because he need that point for his full prime. There is no reason to worry about back checkers because black has no board, has one more blot on 5pt and has only eight checkers to play with.
