to play 65

Bijeli vodi u trci i bacio je 65. Prirodno je da ide naprijed. Iako 16/10 izgleda pametno jer izbjegava direktan šut, ipak je tek 3. potez. Oba bolja napreduju sa back checkerom kako ne bio ostao izoliran na 24pt, a pozicija ostaje kompaktna i povezana. Osim toga checker na 10pt je izložen sa 11 indirekta (63 54 33 61 52 43), stoga je najbolje igrati prirodni 24/13 koji barem sačuva 11 pipseva. 13/8 radi na distribuciji spare checkera, osvaja više gammona, ali manje pobjeda što daje pri vodstvu bijelog 4-2/9 i početnom položaju kjuba inferioran izbor. 

White is ahead in race and he just rolls 65. It is natural for him to run. Even 16/10 looks clever because avoids direct shot, it is only third move in RO. Both better choices run with back checker at least one part. It is important to not leave back checker isolated and to keep position compact and connected. In addition, checker on 10pt is not safe at all. There are eleven indirects (63 54 33 61 52 43). 13/8 improves spare distribution but it is gammonish play and it is not thematic at this score with doubling cube still in center as well.
