Nakon obavezne šestice kojom preskače blokadu u nadi da će biti promašen (dok vodi u trci za 19 pipseva), bijeli može produžiti sa jedinicom i ostaviti 15 šuteva (sve trice za 11, 21 i 65 sa ankore) ili popraviti strukturu i raspodijeliti spare checkere na 5. i 6. polju za ponovnih 15 šuteva (sve četvrtice za 11, 31 22 i 66 sa ankore). Kako je 6/5 očiti dobitak za poziciju, bilo za trku u kupljenju, bilo za mogući napad ukoliko crni napusti ankoru, te je broj šuteva jednak, očito je činjenica kako je 8.polje bijelog u dosegu šestica sa 15.polja važan faktor pozicije. 

After mandatory six which jumps over blockade when is ahead in race 19 pips, white has two solutions for ace. He can continues to 15pt which leaves 15 shots (all 3s 21 and 65 from the anchor) or can improves his structure and spares distribution with 6/5 which leaves also 15 shots (all 4s 31 22 and 66 from the anchor). Because 6/5 is obvious improvement (for bearoff and potential attack if black leaves anchor) and shots counting is equal then fact how white's 8pt is in six pips range from 15pt makes such balance between two candidate moves.
