How do I spot a smothered mate in a middlegame?

Look for a king surrounded by its own pieces, with most escape squares occupied or controlled. Then search for a knight or other piece that can give check while the king has no legal flight square.

What is the difference between a smothered mate and a back rank mate?

A smothered mate normally relies on the king being boxed in by its own pieces, often with a knight delivering the final check. A back rank mate usually traps a king behind its own pawns on the first or eighth rank.

How can a pin help create a checkmate?

A pin can prevent a pawn or piece from moving because it is shielding the king from attack. When that defender is immobilized, a checking move may become decisive because the king cannot capture or interpose effectively.

What should I examine first in a mate in 1 puzzle?

A pin against the f-pawn adds tactical pressure, restricting defensive resources. The key idea is to recognize that material and pawn advantages do not matter when the king is boxed in and a precise mating pattern is available.
