The pin and fork are important tactical maneuvers. In this week’s position, black appears to have a winning pin. However, white escapes with a fork. With this hint in mind please try to find white’s best move.
Black’s rook has just slid over to d8. This appears to pin white’s knight to its rook, because if the knight moves, black’s rook takes white’s unprotected rook.
But not all knight moves lose. That is, white’s knight hops to f6 (see next diagram).
The point is if black’s rook takes white’s rook, white’s knight hops to e8, forking the black king and rook. The white knight next wins black’s rook and white has a decisive two-pawn advantage.
Alternatively, if black’s rook moves its rook to a8 to guard its a6 pawn, white has escaped the pin and maintained its material edge.
The lesson this week is that you can put a fork in pin.
