Forum:Compulsory vs summons

Can Compulsory Evacuation Device be activated (or chained) in response to a summon of a monster without a trigger effect?

EX: I normal summon a The Six Samurai - Yaichi. My opponent can activate Compulsory immediately and chain it to the normal summon of Yaichi to prevent the special summon of another monster (Grandmaster of the Six Samurai)?

If this is right, Can all the summons be chainables?
