What I want to know is: are there any kinds of problems in chess that remain unsolved?

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. Avoid asking multiple distinct questions at once. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
Is there a forced win for White?
You can try finding the perfect Babson: compose a problem with four main lines. They consist of a defensive promotion of a black pawn to a queen, rook, bishop or knight, which forces White to promote to the same piece type in each case.
Examples already exist, but they involve duals, which make them imperfect.
Is it good or not for chess and the players if the World Championship match could be eventually decided by rapid, blitz, and armageddon?
