I live alone and need to do bedikat chametz. Should I hide 10 pieces of chametz myself? Doesn't that defeat the purpose?
My Pardes teacher Zvi Wolf warned us to be very careful when spreading around chametz just to "find" it. Specifically, be careful to not leave any chametz in your nice clean rooms. Eg crumbs from bread, etc.
If you do it, don't overdo it. And think about the crumbs in advance. Eg one slice of bread in a bag--find the
bag with chametz in it, not the chametz sitting on a shelf somewhere.
He said he knew of people who, during Pesach, had found the chametz they had "hidden" before the chag. (Oops!)
