Loshinsky theme
Like-moving black and white pieces stand next to each other in direction of their movement. The former moves away along their common line the latter follows it by moving to the adjacent square.

This superb problem shows the Reciprocal change. Loshinski theme requires three variations by the same white piece following the black piece. Not in this.
I know, but nowadays many composers search extentions to old themes like in this example.
Below is the definition of the Loshinsky theme from WinChloe software:
“Loshinsky: Bicoloured Bristol black-white where second piece (white) moves immediately to the square right in front the one where the first piece moved.”
It says nothing about three variations.
