Reti Opening Smothered Mate in Chess

A “reti opening smothered mate” is a tactical pattern that can arise from the Reti Opening (often via 1.Nf3 and 2.c4) when a knight gives checkmate on a key square while the opponent’s king has no escape squares. The defining feature is the king being smothered—its own pieces block all flight squares—so the check can’t be met by moving the king.
