Prirodan 24/23 13/9 je začudo ozbiljna greška. Nakon što odbaci presiguran 13/8, RO smatra veliki split 24/20 boljom 4 od 13/9, a mali split 24/23 boljom 1 od slota 6/5. Zašto? Bijeli 1 pips u prednosti otpušta kontakt i kreće naprijed. Checkere sa 6pt želi ubaciti u igru i 5pt je vrijedan, no trka je važnija i bijeli ne ostavlja šuteve sa svoje strane. Veliki split pokriva cijelu ploču i dobro izgleda. Crni nema novo unutrašnje polje niti checkera viška na vanjskim poljima. „Dva gore“ je aktivan potez koji provocira protivnika, ali ne komprimitira utrku.

Natural 24/23 13/9 is serious error. 13/8 is too safe and non productive. RO thinks how major split is better four than 13/9 and minor split is better ace than slot. Why? White is one pip ahead in race, he releases contact and start moving back checkers. He wants to put into play checkers from 6pt and 5pt is valuable but race is more important and white doesn't like to leave shots on his side of the board. Major split gives him outfield control and looks good. Black has no new inner points nor spare checkers on outer points. Two up is active play which provokes opponent but doesn't compromise race.
