Bijeli ne može napraviti 3.polje jer ostavlja direktan šut sa svoje strane ploče dok vodi 21 pips. 13/8 dovodi checker viška na 8.polje i rasterećuje središnje. Međutim, izgleda kako checker ne može ostati na 8.polju jer 13/10 ostavlja bijelog ranjivog na obje strane. 63 54 62 53 ukupno 8 šuteva šalju bijeloga na bar. Bijelome ne treba blokada protivnika kako bi ga stigao u trci jer on već vodi. Njegov plan igre je dovesti stražnji checker na sigurno, zadržati prednost i uduplati igru. Stoga sigurni 13/5 ima prednost. Rizičniji 13/5 nije opravdan kod 2-1/9.

White can't make 3pt because it leaves direct shot on his side of the board when he is ahead 21 pips in race. 13/8 creates spare checker on 8pt and unstacks midpoint which is nice but there is no good three then. 13/10 leaves white vulnerable on both sides. 63 54 62 53 total 8 rolls sends white on the bar. White doesn't need prime to block his opponent because he is ahead in race. His game plan should be just to bring last back checker closer home into safety and double in proper moment. Safe 13/5 is winner. Risky two down is overplay at this score.
