a good player should know how to attack and how to defend himself/herself too. Cause if you only attack , your opponent may block your attack and destroy your centre. you must play for the centre... only when it' s sure it can't be broken you can think of an attack . When you think of an attack you must have at least 2 extra pieces in that zone without the one sacrificed. Althought, the attack doesn't work .... believe me....
