All the professional engines meet this requirement.

ChessMaster and ChessAssistant will do this.  Probably many others also.

Don't know of any that will do this.  But most of them will search a position
for you.

I don't have any "deep" engines except for the free ones Crafty and Amy.

I suggest Chess Assistant.  You can pair your program against strong
professional programs.  You can also use their extensive database to create
books.  But it is fairly expensive.  A second choice would be ChessMaster.  I
have heard that recent versions of Rebel will work, but I only have older
copies.
