Below the board

A calm opponent, close by

Easy lets you look around after months away. Medium is a proper lunch fight. Hard digs in; Master thinks longer. None of them are titled players in a trench coat — they’re dials on a local worker. Same oak as home, with the difficulty knobs named out loud.

Strength

Easy through Master. Change it any time — the board does not make a fuss. Local 2-player hides the dials and lets a friend take the other color on this screen.

Local worker

Replies are searched in a Web Worker on this device. No “connecting to engine” spinner that dies after thirty seconds.

Record

A small local tally in this browser. Clear site data and the gossip goes with it — no cloud vault.

Play chess against computer

Some days you want a reply without waiting for anyone else to sit down. That’s what this page is for. Pick a strength, move a piece, and the other side answers on this device — not after a spinner that says “connecting to engine” for thirty seconds and then dies.

Easy is for rusty afternoons and first games after months away. Medium is the default mood: enough bite to punish a free queen, not so mean you resign on move twelve. Hard digs in. Master thinks longer. None of them are “FIDE rated.” They’re dials on a local worker, not a cloud coach with a monthly plan.

If someone is sitting next to you, flip to Local 2-player and pass the device. Same oak board. Same rules. The difficulty knobs just go quiet until you’re alone with the machine again.

When

When to use

Solo lunch. Practicing without chat. Checking whether you still hang queens for free. A short game when you don’t want to commit to a stranger’s clock. Same-screen play when a classmate wants the black pieces for ten minutes.

When not

When not to

You only want the sharp tactical moment — go to puzzles and skip the opening noise. You still mix up bishops and knights — start on how to play, then come back on Easy. You wanted fifty other browser games in a neon grid — wrong house; we only do chess here.

Defaults

Assumptions

Standard Western rules. White moves first unless you swap colors before the first move. Difficulty changes how deep the worker looks and how greedy it gets — not a magic “always win” cheat code. Record is a small local tally in this browser. Clear site data and the gossip goes with it. Sound stays off until you poke it.

Steps

How

  1. Choose Vs AI, then Easy / Medium / Hard / Master — or Local 2-player if you’re sharing the screen.
  2. Pick your color if you care. AI takes the other side. You can swap before move one.
  3. Move a piece (click/drag on desktop, tap-tap on a phone). Wait a beat while the worker thinks.
  4. Blunder, use Undo if you must, Hint if you’re stuck, New game when you’ve had enough of this mess.

Worked notes

Examples

  • You’re rusty after months away → Easy lets you finish a game without getting mated in eight — ego bruised, not demolished
  • You came from a site that froze on “connecting to engine” → here the thinking happens in a Web Worker on this device
  • A friend leans over and wants black → switch to Local 2-player and pass the laptop; no second login
  • You keep hanging the queen on Medium → drop to Easy for a game, then try puzzles that punish loose pieces

Watch-outs

Gotchas

  • Hard and Master are meaner, not grandmasters in a trench coat. Don’t quote a rating at them.
  • Closing the tab mid-game can lose the position if nothing was saved — we don’t keep a cloud vault of your half-finished fights.
  • A lot of “play chess against computer” results are adware wrappers or iframe malls. This URL is just a board and a worker.
  • Hint is a suggestion with a reason when we can give one — not “the engine says +2.7, trust me.”

Why this URL

People type “against computer” like a mission

The homepage is already a playable game. This page exists because searchers often want the difficulty sermon labeled out loud — Easy, Medium, Hard — before they touch a pawn. Same engine family as home. Fewer adjectives about the rest of the house. More knobs on the fight itself.

If you landed here from a school filter day, you’re still looking at one chessboard, not a directory. Unblocked has its own door when that’s the mood. Here the mood is: pick a strength and play.

Under the hood

Local worker, not a subscription pipe

Moves are checked and replies are searched in a Web Worker so the page doesn’t freeze while you stare at the oak. That matters on a tired laptop. It also means there’s no account tether and no “engine online” badge pretending a distant server is your coach.

You’ll still lose games. Local doesn’t mean soft. It means the thinking stays near the board you can see.

Next doors

When the full game feels like too much homework

Puzzles drop you into one sharp position — fork, pin, quiet mate — without the opening parade. How to play is for the friend who still thinks knights slide like bishops. Openings for beginners is three habits, not a Sicilian farm. Come back here when you want the long fight again.

Controls

On this board

Vs AI locks the difficulty row; Local 2-player hides it and lets you pass the device. New game clears the fight. Undo steps back while you practice. Hint suggests a move when we can explain the idea. Sound stays muted until you turn it on — libraries exist. Fullscreen is for when the rest of the desktop is noise.

FAQ

Common questions

Can I play against a real person online?
Not over the network on this page. You can pass one device for local two-player, or play the computer. Different moods, same board.
Is this Stockfish in the cloud?
No subscription pipe. A local worker on this device searches for a reply. Strengths are labeled Easy through Master — meaner, not titled.
Does Undo count as cheating?
It’s practice furniture. Use it. We’re not running a rated event.
Why isn’t the homepage enough?
Home is already playable. This door is for people who typed “against computer” and want the difficulty knobs named before move one.
Will my games sync to another phone?
No cloud account. Record and position live in this browser unless you clear site data.
Can I play as Black?
Yes — pick your color before the first move. The AI takes the other side.
