A Quoridor variant

FOUR-WAY WALLS
==============
* One player has stones n s e w, the other N S E W.
* Each stone must try to cross the boundary furthest in its name-direction.
* With 13444 equalizer, in each turn each of a player's stones, (move order at the mover's discretion), must move one orthogonal step; then a wall is played (but not on the boundary); all as in Corridor.
* If any stones are adjacent to the moving stone in its chosen direction, it may jump them to the next vacant cell. If a wall blocks this direction part-way through such a jump, either unblocked right-angle may be turned.
* The winner is the first player to get three stones off the board.

This is a very fun game. Both player must, at each turn, decide which enemy player they want to delay, while advancing their own as far as possible.
