There's a saying in checkers circles — "a bad opening leads to a bad midgame." I used to dismiss that as an exaggeration until I started paying close attention to how my games unfolded. Almost every time I lost a match in Checkers Master, I could trace the problem back to a weak or passive opening. My pieces were in the wrong places, I'd given my opponent center control, or I'd moved the same piece twice when I should have been developing others.
The opening phase of checkers — roughly the first six to ten moves — sets the stage for everything that follows. Get it right and you'll spend the rest of the game pressing an advantage. Get it wrong and you'll spend the rest of the game playing catch-up. Let's fix that.
What the Opening Phase Is Actually About
Most beginners think the opening is about moving pieces forward. It's not — or at least, that's only a small part of it. The opening is really about three things:
- Development: Getting your pieces into active positions where they can influence the game
- Center control: Occupying or threatening the central squares of the board
- Flexibility: Keeping your options open so you can adapt to what your opponent does
A well-played opening doesn't lock you into one plan — it gives you multiple plans. You want your pieces to work together, support each other, and be ready to shift formation as the game evolves.
The Single Corner Opening
This is one of the most time-tested openings in checkers. You advance the piece on the right side of the board (from your perspective) diagonally toward the corner. This is a solid, classical choice that gives nothing away immediately while positioning a piece for central influence later.
Why it works:
- It's hard for your opponent to attack directly without giving you an immediate jumping opportunity
- It develops a piece toward center while keeping your back row intact
- It's flexible — it doesn't commit you to a specific midgame plan
The Single Corner is especially effective in Checkers Master because the AI often tries to mirror your opening. If you play Single Corner and the AI mirrors, you're already in familiar territory with a solid formation to build from.
The Old Faithful: Double Corner Opening
Another classic. In the Double Corner, you advance pieces from both corners of your side simultaneously in the first two moves. This immediately establishes a broad front and makes it hard for your opponent to find a clean attacking angle.
The double corner formation looks aggressive on the surface, but its strength is actually defensive: by advancing both wing pieces, you close off diagonal attack lanes on both sides while positioning pieces to advance toward center on the next moves.
I played Double Corner as my default opening for about a month and it served me really well against the standard AI setting. The broad front was difficult for the computer to break through without giving me multi-jump opportunities.
The Cross Opening: My Personal Favourite
I discovered the Cross Opening by accident — I was experimenting with different first moves and stumbled onto a formation that just felt right. The Cross involves advancing your two most central pieces in the first two moves, creating an X or cross pattern that dominates the middle of the board immediately.
It's riskier than the classics because you're committing your central pieces early, leaving some flank squares less protected. But the reward is immediate center dominance, which gives you attacking options that passive openings don't have.
When to use the Cross:
- When you want to play an aggressive, attacking game
- Against an opponent (or AI level) that tends to play passively
- When you're comfortable handling a bit of early board tension
When to avoid the Cross:
- When you're playing a more advanced opponent who knows how to exploit early center commitments
- When you're still learning and want a more forgiving opening
Common Opening Mistakes to Avoid
I've made all of these. Learn from my embarrassment:
Moving the same piece twice in the first five moves. This is the opening equivalent of putting all your eggs in one basket. Every time you move one piece twice, another piece is sitting idle. Develop all your pieces, then start coordinating them.
Moving only edge pieces. Edge pieces are "safe" in the sense that they can only be attacked from one direction. But safety isn't the goal of the opening — development is. Pieces stuck on the edge contribute nothing to center control.
Releasing the back row too early. I've talked about this in other articles, but it bears repeating: your back row pieces are blocking your opponent from getting Kings. The longer you hold them, the harder you make your opponent's endgame. Don't advance back row pieces until the midgame forces you to.
Reacting to every opponent move. If your opening strategy is purely reactive — just responding to whatever your opponent does — you have no opening strategy. Have a plan. Yes, adjust it to what your opponent plays, but always be working toward your own formation goal, not just blocking theirs.
Leaving pieces isolated. An isolated piece — one that has no friendly pieces diagonally adjacent to support it — is a target. Before you advance a piece, make sure it will have support when it lands. If it doesn't, it's vulnerable.
The Pairing Principle
One of the most useful frameworks I picked up for openings is what I call the "pairing principle": always try to advance pieces in pairs. When one piece moves forward, the piece diagonally behind it should be positioned to support it. This creates a two-piece unit that's much harder to attack than individual pieces.
In practice this means alternating your development between different parts of the board: advance a center-left piece, then develop a center-right piece to support it, then extend another piece on the left, and so on. You're building a web of mutually supporting pieces rather than a disorganized scatter of individuals.
The pairing principle sounds simple but applying it consistently in an actual game takes practice. The temptation is always to make the most immediately "active" looking move. Resist that temptation in the opening. Build your foundation first.
Reading Your Opponent's Opening
Understanding your own openings is only half the equation. You also need to be able to read what your opponent is doing and adjust accordingly. Here are the key things to watch for:
- Are they claiming center? If yes, fight them for it — don't cede the middle without a battle
- Are they playing aggressively? Set up defensive formations and look for counter-attack opportunities
- Are they playing passively? Take control of center and start building attacking formations
- Are they advancing one side heavily? Look to exploit the weakened opposite side
In Checkers Master, the AI's opening style varies between difficulty settings. At easy difficulty, it's quite passive and reactive. At harder settings, it actively contests center from the first move. Knowing what to expect helps you choose the right opening approach for each session.
Building a Personal Opening Repertoire
Professional checkers players have specific openings they've studied and practiced until they can execute them automatically. You don't need to go that deep — but having two or three openings you know well is genuinely useful.
My recommendation: start with Single Corner (reliable and safe), then add Double Corner (broad and flexible), then experiment with something more aggressive like Cross when you're feeling confident. Practice each one deliberately for a few sessions before moving to the next.
Keep a mental note of how each opening tends to develop for you. If one consistently leads to positions you feel comfortable in, lean into it. Your "best opening" isn't the theoretically strongest one — it's the one that leads to positions you understand and can navigate confidently.
The Opening Sets Up Everything Else
I want to close with the thought I opened with: the opening sets up the midgame, which sets up the endgame. There's a direct chain of causation. A loose, passive opening leads to a chaotic midgame where you're constantly reacting. A crisp, purposeful opening leads to a midgame where you have real options and genuine attacking chances.
The good news is that the opening is also the most learnable part of checkers. Unlike the complex calculation-heavy midgame, the opening is about principles you can internalize and apply consistently. Master the opening principles I've described here, and you'll find that everything downstream in the game gets easier.
