AMAZONS

Copyright (c)1988 Walter Zamkauskas

Amazons is played on a 10x10 board, with the following setup:

MOVES - White moves first, and turns alternate. Each turn consists of two parts, and both parts are mandatory.
The player first moves one of his amazons. Amazons move as a chess queen. Amazons may not jump over or land on other pieces or arrows.
Next, the Amazon which just moved "fires an arrow" from its new location. Arrows can be show in any direction, the same as a chess queen, and may not jump over or land on other pieces or arrows. Once an arrow lands, it acts as an immovable barrier to all arrows and amazons.
GOAL - The first player that cannot finish his turn, loses.
 
An example

White moves 1. g1-b6,c7. The arrow landed on c7, so neither player can cross that intersection.

There is a ZRF to play Amazons with Zillions. There is also a variant Killer Amazons where it's possible to capture any Amazon of either color. 

Another variant from Chris Huntoon, Cowboys, uses Knights on a 8x8 chess board (with no capture):
