Kada protivnik ima jaku ofenzivnu poziciju često je ispravno napasti i uzeti mu pola slijedećeg bacanja. Možda baci 55 66 65 i ne uđe u igru, što sa dva blota, od kojih je jedan u dometu šestica, mijenja situaciju na ploči. Istina je da checkere sa midpointa treba jednom ubaciti u igru, ali sada nije pravi trenutak. Bilo bi prepasivno. Ako sada ne udari, bijeli ostaje nezaštićen, sa 14 protivničkih checkera u blizini. Napad mu kupuje vrijeme da uradi nešto sa back checkerima. Ako crni uzvrati, onda bijeli može napraviti ankoru i učvrstiti položaj. 

When your opponent has strong offensive position it is often correct to attack him which will take half of his next roll. Maybe he will roll 55 66 65 and will stay one more turn on the bar. Then you can pick up eventually his unprotected blots around. It is true how white should put his checkers from midpoint into play but it is not the most important right now. It would be too passive. Black has 14 checkers into zone and with tempo hit white protects himself. Attack buys him more time to do something with back checkers. If black returns from the bar, white gets chances to anchor which could consolidate his position.
