The Fork
📋 What it is
A fork creates TWO threats at once, so your opponent can only block one — and you win with the other.
🗣️ Coach says
The killer move in almost every line game: set up two winning threats in one move. Your opponent can block only one; you complete the other. Look for spots where a single disc opens two lines.

A "double threat" fork is unstoppable — no matter which one your opponent blocks, you complete the other next turn.
