Openings for Beginners

What Is an Opening Line?

An Othello opening (or "book line") is a sequence of early moves considered sound for both sides — paths that years of study have shown don't badly damage either player's position. You don't need to memorize them, but knowing the common shapes and the idea behind each one keeps you from collapsing in the opening.

The First Fork in the Road — Diagonal vs. Parallel

After Black's first move (in standard notation, f5), White's reply sets the character of the opening. Depending on the direction the discs are flipped, play divides into two broad families.

• Diagonal openings: discs are flipped along a diagonal. These tend to be calmer and are friendlier to beginners.
• Parallel (vertical) openings: discs are flipped in a vertical line. Contact is sharper from early on, and the variations get more cutting.

Start by getting comfortable with the diagonal openings first.

Named Openings

Othello openings have nicknames, often because the disc shape resembles an animal. You don't have to learn the names, but knowing that these shapes exist gives you a place to start.

• Rabbit: a classic of the diagonal family. Well balanced — the natural first opening to learn.
• Tiger: an aggressive line often chosen by Black, aiming to seize the initiative in the middlegame.
• Cow: a slow, patient setup that builds calmly.

Play in Game Dojo and watch which shapes the engine's "Best" moves follow. The openings stick without much effort.

Three Principles to Keep in Mind Early

1. Keep discs few and central. Don't spread early. Don't build walls.
2. Don't play X- or C-squares early. Don't open a path to your own corner.
3. Watch your opponent's moves. Increase your options and shrink theirs.

When Your Opponent Leaves the Book — Your Chance

Opponents often won't follow the book. Usually, an off-book move is a loss for them. Don't panic — return to the basic principles (corners, mobility) and punish the slack.
