The Pawn is the best defender in most cases. It has other powers besides simple protection, as when coupled with a Bishop or a Queen-- mutual protection is enabled.
So, the Pawn Link is the static relationship, usually, when a piece (not another Pawn) sits on a Pawn's diagonal in an adjacent file. It is especially deterring when a chain of protectors are in play. Who wants to make a series of exchanges with pieces when the other side has a Pawn in the mix?
There is also that special case when the Pawn is on the seventh rank to support a piece that shifts into a dynamic Pawn Link at the last rank-- now if that piece is captured, the Pawn recaptures and promotes!
All the various cases that can be applied to Pawn Links will be included in this game collection, with the exception of Pawn Link Mates. They have their own game collection, then.
ChessCoachClark (CCC) originated this game collection in September 2024 and he updates it on occasion. This project is a work in progress, culling games from various sources, including several chess training books and personal research. The games are ordered by date (oldest first), not by importance.
Be well.
Be safe.
