2.How
How it works
Three steps. Then just play.
- 01
Pick your openings
Choose one opening for White and one for Black in the extension popup, or type in your own moves.
- 02
Play a bot
Start a game against any Chess.com bot. The extension sees which color you have and loads the right plan.
- 03
Follow the tiles
The piece to move and its target square are outlined. Play the move and the next one appears.
3.Design
Built to teach, not to play for you
Just enough help to make the moves stick.
- One move at a time. Only the next step shows, so the board never gets cluttered. Want to see further ahead? Show two, three or all of them.
- Subtle by design. A thin outline and a faint tint, so you still see the pieces and the position.
- Knows when you go your own way. Move a piece somewhere else and its tile quietly steps aside. The rest of the plan keeps going.
- Reads the real board. Takebacks, reloads, new games: it works from the actual position, so it never falls out of sync.
4.Plans
Built-in openings
8 for White, 7 for Black.
Each plan is a set of your moves. The outlined squares show where your pieces are headed.
When you play White
White · Classical
Italian Game
Classical development aimed straight at f7. The slow c3–d3 version gives you a safe, flexible middlegame.
1e42Nf33Bc44c35d36O-O7Re18Nd2
White · Positional
Ruy Lopez
The oldest test of 1…e5. Steady pressure on Black's center and a long-term plan with c3 and d4.
1e42Nf33Bb54O-O5Re16c37d4
White · Gambit
Scotch Gambit
Open the center with d4, then develop with Bc4 instead of taking back. Castle, push e5, and play for a fast attack.
1e42Nf33d44Bc45O-O6e57Re1
White · Principled
Queen's Gambit
Offer the c-pawn to win the center. Principled, respected at every level, and full of clear plans.
1d42c43Nc34Bg55e36Nf3
White · Solid
Colle System
A quiet setup with a sting: build with e3, Bd3 and Nbd2, then break with e4 at the right moment.
1d42Nf33e34Bd35c36Nd27O-O
White · Flexible
King's Indian Attack
A King's Indian with the extra move. Fianchetto, castle, and launch a kingside attack with e4–e5.
1Nf32g33Bg24O-O5d36Nd27e4
White · Positional
English (Botvinnik)
Control d5 from the flank with c4, Nc3, g3 and Bg2. The Botvinnik setup adds e4 for a firm grip.
1c42Nc33g34Bg25e46Ne27O-O8d3
When you play Black
Black · Dynamic
King's Indian Defense
Let White take the center, then hit back with …e5 and a kingside pawn storm. Sharp and ambitious.
1Nf62g63Bg74d65O-O6e5
Black · Solid
Caro-Kann
Rock-solid against 1.e4: …c6 and …d5, then develop the light-squared bishop before …e6.
1c62d53Bf54e65Nd76Nf67Be78O-O
Black · Sharp
Sicilian Dragon
A fianchettoed bishop breathing down the long diagonal. One of the sharpest replies to 1.e4.
1c52d63Nf64g65Bg76O-O7Nc6
Black · Counter-attacking
French Defense
…e6 and …d5 build a sturdy pawn chain. Counter-attack the center with …c5 and piece pressure.
1e62d53Nf64Be75O-O6c57Nc6
Black · Classical
Queen's Gambit Declined
The classical answer to 1.d4: hold d5 with …e6, develop smoothly, and castle into safety.
1d52e63Nf64Be75O-O6Nd77c6
Black · Solid
Slav Defense
Support d5 with …c6 and keep the c8-bishop free. A favorite of world champions for good reason.
1d52c63Nf64Bf55e66Nd7
Black · Aggressive
Stonewall Dutch
Pawns on f5, e6, d5 and c6 lock down e4. A clear setup with real kingside attacking chances.

Questions
Q1Is it allowed on Chess.com?
Chess.com's Fair Play Policy doesn't allow browser extensions during games against other people. The Chess Opens extension only switches on in games against Chess.com's computer bots and on the analysis board, which the policy doesn't cover, and stays off everywhere else.
Q2How does it know whether I'm White or Black?
It reads the board's orientation. When you play Black, Chess.com flips the board and the extension loads your Black opening. You can also force a color in the settings.
Q3What happens if I play a different move?
The tile for that move disappears and the rest of the plan carries on. Prefer a clean board once you've left the plan? Switch the setting to hide the whole opening instead.
Q4Can I add my own opening?
Yes. Choose 'Custom…' in the settings and type your moves in order as from/to squares, like d2d4 c1f4 e2e3, with O-O or O-O-O for castling. The extension checks every move as you type.
Q5Does it collect any data?
No. Your settings live in Chrome's own storage. There are no analytics, no accounts, and nothing is sent to a server.
Q6Which browsers does it work in?
Google Chrome, plus Chromium-based browsers that can install from the Chrome Web Store, such as Microsoft Edge and Brave.
