Connect 4 openings
The best first move is usually the center column
Starting in the center gives your first disc access to the most winning lines. It does not guarantee a win, but it gives you the most flexible position to build from.
Column priority
- 1. Center: most possible four-in-a-row paths.
- 2. Adjacent center: keeps diagonal and horizontal pressure.
- 3. Outer columns: useful later, but weaker as a default opener.
When should you adapt?
After the first few moves, the best column depends on threats, blocks, and whether a move gives the opponent a forced win. If a position is no longer a clean opening, recreate it in the solver and compare the recommendation against your instinct.
The goal is not to memorize every line. It is to learn which board shapes make the center valuable, which moves create two threats, and which quiet-looking columns are dangerous.
