RéTi Opening Deflection From Checkmate Chess Puzzles

The Réti Opening Deflection from Checkmate is a tactical defensive motif that appears in Réti-style positions when a piece is forced away from a key square to stop a mating threat. In practice, the defining feature is a move that lures or drives an attacking piece off the line, file, or diagonal it needs for mate, often while White’s flexible knight and fianchetto setup keep the king safe.
