CONNECT, don't EXPAND

New page

The pivotal moment of Churn is when a player makes a new largest group.

There are two ways to make a new largest group: EXPANDING a group by adding one stone to it, and CONNECTING two existing groups by adding a stone between them.

CONNECTING is much stronger, since it makes a much larger group, but EXPANDING is required by the rules if possible, since you're obligated to make the smallest possible group each turn.

A good heuristic for playing Churn, then, is to try to force yourself to CONNECT, and force your opponent to EXPAND.
