Bijeli zaostaje u trci 26 pipseva, a možda će još i više ako mu crni pokupi blot u vanjskom polju na kojeg ima dvostruki šut, stoga bijeli treba povećati kontakt i napraviti ankoru na 23pt odakle ima bolju kontrolu ploče i više šansi za šut. Nakon toga može napraviti 4pt sa checkerima sa 6pt što je vrlo efikasno. Time zatvara tri najbolja polja u svojoj kući i kreira četiri polja dugu blokadu. Ako napravi ankoru na 21pt crni tada može sa 64 44 55 66 napasti i otjerati bijeloga sa dubokih polja svoje kuće i preuzeti kontrolu nakon čega nezgodna bacanja izvodi iza leđa bijelom.

White is 26 pips behind and black has double shot on his blot so white has to increase contact and make 23pt anchor not 21pt because from 23pt he has better board control and more chances for shot. After that he has to make 4pt which is next point in a raw which extents his prime into respectable one. Now black can't PoH with 64 44 55 66 nor force white to enter on higher points in his homeboard.
