Two like moving pieces of different colour stand on the same line. In variations black moves along the line away from the opponent’s piece, which in turn moves the same distant in the opposite direction. The manoeuvre repeats at least once in another variation, in which distant grows 1+1 squares. Compare with Loshinsky theme where once thematic piece follows the piece of opposite colour, and with Anti-Loshinsky theme where two pieces are moving toward to each other.
