Learn How to Deflect: Decisive Material Gain
This chess endgame puzzle is a classic example of using activity to convert a static material deficit into a tactical win. White’s rook is active on the open file, while Black’s king and back rank pieces are awkwardly placed. The key idea is deflection: force the king to step away from a critical square so a major piece can be won. It is a practical example of how classical chess principles reward active rooks and forcing moves over passive defense.
