This game is played on a 8x8 square board, with the following setup:

SLIDE - Each stone may move one or two cells forward (no diagonals) or sideways to an empty cell.
Sideways moves are only allowed when there are no forward moves.
There are no captures in this game.
EVADE - If the stone faces another stone (either color) directly forward, then it may also move diagonally forward any number of empty squares. Several evasive moves in a row are allowed, using the same stone. 
At the end of such a series of evasive moves the player have an additional sliding move available using the same stone.
GOAL - A player who fills the opposite two rows wins.

An example

The marked black stone at a7 can evade to cell [1] and then slide to cell [2] blocking 3 white stones.

There is a ZRF to play Evasion with Zillions.
