From a recent blitz game...
This can hardly be called a puzzle or that much of an exercise, since, effectively, it plays itself, but it was good to have seen this ( + a couple of previous moves to set it up ).
It is undeniable though, that Black played himself into this situation.
|White to play and win|
Highlight for solution [ 1.Nf6+ Kf8 loses material or is mate via Rh8+, Rh7+, Be6# or Kg8 ( as played in the game ) leads to mate with 2. Rh7# ]
