Nakon što zatvori 2pt i potpuno blokira crnog, bijeli sa 8/5 unosi spare checker u kuću pazeći pri tome na distribuciju. Preostalu tricu igra kao 9/6. Time ubacuje još jedan checker u kuću (dok ih sve ne ubaci, ne može ih niti pokupiti) i zadržava punu blokadu. U kupljenju se inače teži posložiti checkere u formaciju koja sliči trokutu. Bijeli zaostaje u trci za 20 pipseva i plan mu je zatvoriti kuću kreirajući istovremeno što više spare checkera na višim poljima, kako bi ih mogao pokupiti što više prije nego otvori 6pt.

8/2 is mandatory. It finishes full prime and blocks black last checker. 8/5 brings one more checker into homeboard and gives fine spare distribution. Last three is 9/6. It brings one more checker into homeboard and keeps full prime. You can't bear off your checkers if you don't bring them into homeboard in first place. Ideal bear off formation is triangle with most checkers on 6pt, then on 5pt etc. White is 20 pips behind in race and his game plan is to close his homeboard creating in same time as more spare checkers on higher points as he can, in order to bear off all of them before opens 6pt.
