RéTi Opening Use The Pin Chess Puzzles

Réti Opening Use the Pin refers to a tactical idea that appears in Réti structures when White develops with 1.Nf3 and often fianchettoes the king’s bishop, creating pressure on a pinned piece or along a pinned file. A defining feature is the bishop on g2 or b2 supporting a pin against a knight or pawn that is tied to the king or queen, often after ...d5, ...Nf6, and ...Bg4 or ...Bb4. In these positions, the pin is used to restrict Black’s development and make central breaks harder to execute.
