RéTi Opening Clearance For Checkmate Chess Puzzles

Réti Opening Clearance for Checkmate is a tactical motif that appears in Réti-style positions when a piece or pawn is moved away to open a line for a mating attack. In practice, the defining feature is a clearance move that removes a blocker from a file, diagonal, or key square so a rook, queen, or bishop can deliver mate. It often arises after 1.Nf3 and flexible development, when the opponent’s king is still exposed and lines can be opened with tempo.
