Solution:

White would checkmate by transferred his king to f2, then 5. Tg 3 dull play. Black, on the other hand, defends himself with a self-imprisonment, which would lead to a stalemate if White's threat was executed after 3. Ke1 b5 . When executing the stalemate, however, the black pieces cross the intersection on b5, which White can take advantage of with a Nowotny adjustment .
