SanQi is played on the following initially empty hexagonal board. There are initially offboard enough red, blue and yellow stones.
Some words from the author: The first player should concentrate on forming circles, while the second attempts lines. The triangle will often become a threat that can be exploited for positional advantage by both players. Remember there are three different colors which can be played. Use more than one to perform blocking moves. If an opponent seems to favor one color, you can take advantage by playing the other two. Just because you can replace a stone does not mean that it is wise to do so. In fact it might be advantageous to secure that stone by placing more of its color adjacent. If an opponent successfully blocks a developing pattern, don't be afraid to abandon it. In fact, either start a new one somewhere else on the field or begin building on the opponent's blockers. In either case, try switching colors. Watch out for those triangles, they can sneak up and hinder a developing pattern.
First player turn. If he drops a red stone at  trying to win next turn by replacing (4 reds versus 2 blues) the marked blue stone in the next turn (thus making a circle) then he will lose because the second player drops another red at cell  making a red triangle of six stones.
second player win
The second player drops a stone at cell  and wins. The first player cannot protect the red marked stone to be replaced, even if he drops a red stone at cell . If that happens, the second player first replaces the yellow marked stone and the resulting 4-2 difference cannot be changed.
There is a ZRF to play SanQi with Zillions.
