to play 11

Bijeli je bacio 11 kojim mora razbiti kuću. "Čisti polja od kraja i ne postavljaj nikakva pitanja." Nakon 6/5(2), čini se "pametnim" sačuvati jedan checker na 5.polju kako bi se duže održala kuća od pet polja i mogla odigrati jedna više četvrtica. Međutim, nakon 44 treći checker na 5.polju samo bi stvarao probleme. Zatim, crni ima tri checkera na baru, gammon je praktički osiguran i bijeli jedino treba dovesti stražnje checkere, te očistiti polja u kući sa što manje problema. Kako bi očistio 5.polje, prvo treba doći na dva checkera tamo.

White roll 11 and has to break his board. "Clear from the rear and don't ask any question", is old saying which can be applied here as well. It is "too smart" to save one four and leave three checkers on 5pt. There is no reason for that. At first, 44 will play pretty ugly after such move. Also, black has three checkers on the bar so gammons are almost sure. White only needs to bring his back checkers home without any troubles. In order to clear 5pt, he first has to strip that point and come to two checkers there. Third checker is redundance.
