This game is played on an empty 1x9 board. Each player has 4 stones off board.
Green's turn. He moves d1e1. Then, Red must capture f1:d1 and Green wins by moving his last stone at a1 to b1.
Some words from the author: I think I have created the simplest strategy game. I call it Motala Strom (isn't that a really catching and commercial name), that is the river that flows through my beloved Norrkoping, Sweden. [...] I have tested this game with Zillions thousands of time and to my surprise, it seems to work and actually be very challenging and have a lot of depth and strategy.
