Smothered Mate
A knight delivers check while the king's own pieces occupy every adjacent escape square.

A smothered mate is a knight checkmate against a king completely boxed in by its own pieces. Because a knight jumps, the attack cannot be blocked, and the surrounding friendly pieces prevent the checked king from moving away.
Look for a king in a corner or beside a crowded pawn shield with no empty neighboring square. Next, map the knight checks that attack the king from a protected square. The pattern works only when the knight cannot be captured and the king truly has no legal exit.
In the playable position, White's knight jumps from h6 to f7. From f7 it checks the king on h8, while Black's rook on g8 and pawns on g7 and h7 fill all three adjacent squares. Knight checks cannot be blocked, so Nf7 is checkmate.
Crowded king positions demand extra attention to enemy knights. Create a flight square before the net closes, keep control of the knight's checking square, or make room for a defending piece to capture the attacker. A full pawn shield is not automatically a safe one.
No. A knight's attack jumps directly to the king, so no piece can interpose. The defender must capture the knight, move the king, or prevent the move before it happens.
No, but corners make the pattern more common because the board edge removes escape squares. The defining feature is that the king's own pieces occupy every remaining legal exit.
