The extended betza notation is explained here. The "fs" is understood as specifying a direction relative to the initial step, so it indicates that the gryphon moves, after the first step, forward and sideways relative to the direction it first moves. It is a more complex notation, but it allows for more possibilities.
I notice here that the knight's move in the rules is different from that in the interactive diagram. Which one is correct?
