Colle System: Rhamphorhynchus Variation

About this opening

The Rhamphorhynchus variation is a cousin of the Pterodactyl, reached via a move order where White captures on c5 before Black replies with the ...Qa5+ check to regain the pawn. Black banks on the fianchetto and counterplay on the long diagonal in an asymmetrical position. With its prehistoric name, it is a rare, eccentric line, favored by players seeking originality.
