Problem
Chess.com is the biggest chess site in the world and the one you're supposed to be a little embarrassed to love.
Insight
Nobody has ever been embarrassed to love Mittens. The site's best brand moment was the one time it stopped being a company and started being a character.
Idea
Battle of the Greats. A short-form series where the legends of chess, rebuilt as engines from their own games, finally get a rematch with the cat. Sixty seconds, one game, one "meow." The legends have history. Mittens has a record.
Written by someone with 25,000 games on the platform and a rating he'd rather not put on the tale of the tape.
The Concept
Open source has a license. It doesn't have a personality. Chess.com does, and it's a cat with a rating of 1 that beat everyone in January 2023 and became the biggest traffic spike in the site's history. The streamers who say they prefer the other site are the ones who built the legend.
Battle of the Greats brings the cat back as a franchise. Each episode is a boxing card: ring walk, tale of the tape, bell, then a real game on the real interface against a legend's engine. Every episode ends on a cliffhanger, and the cliffhanger is a live position. You can play it against Mittens from that exact spot, on one site only. The next episode opens by revealing how it actually went.
That's the mechanic doing the marketing. "Finish the game" beats "sign up" every time, and it can't be copied, because the cat lives here.
Legends are chosen for what can ship: players Chess.com already has bot relationships with, and public-domain-era masters whose engines are built from their own games.

The bell 30 sec
Hard cut to the real Chess.com board. Magnus bot as white. Moves play at engine speed. Three caption beats:
Move 8. Magnus develops cleanly. He's playing it straight. He respects the cat.
Move 14. Mittens plays something ugly the eval bar doesn't punish. That's not a move. That's a threat.meow
Move 22. The position is unclear. Eval bar hovering at zero. Nobody in this ring knows what's happening.
0:47
Move 23. Mittens to move. Freeze. 6 sec
Crowd noise drops out. One line at a time:
Mittens is thinking.Mittens does not think.This is new.
0:53
Cut to black. Bell. 7 sec
Position 001 is live. Finish it.chess.com/mittens · Ep. 02 Thursday.
Why it's built this way. The rating-1 gag is Mittens's original bit, so the tale of the tape is doing brand memory, not inventing. "He respects the cat" is the tone rule for the series: Magnus is never the joke, the cat is the joke, and the cat is winning anyway. Move 22 hovering at zero is the important beat, because the cliffhanger has to be an honest position. If the community can see it's rigged, "finish it" dies. And Thursday turns a video into a schedule, which is what a franchise is.

The Series
Six episodes, one a week. Every episode ends in a live position. Every episode opens by settling the last one.
The best player alive, and the first one to take the cat seriously. Ends on move 23 with the eval at zero and Mittens, for the first time in recorded history, thinking.
The most aggressive champion who ever lived plays the way he always did: straight at the king. Mittens does not have a king so much as a place where the king is. Ends with Kasparov up a piece and Mittens up something nobody can name.
The magician from Riga sacrifices a knight on move 9 for reasons that made sense in 1961. Mittens takes it. Then takes the next one. Ends with three pieces hanging. This is either a masterpiece or a crime scene. Position 003 is live.
The cleanest technician in history refuses to be baited. Thirty moves of nothing happening, beautifully. Ends in a pawn endgame that looks equal. Capablanca has never lost a position like this. Mittens has never seen one.
The 1858 game, replayed against the cat: open lines, quick development, checkmate in the air. Morphy is winning by move 15 the way he always was. Ends when Mittens plays the engine's only move. Did the cat just find that?
The finale isn't an engine. Hikaru plays the cat on stream, one game, no takebacks, the eval bar in real time. The cliffhanger is real because nobody knows the ending, including Chess.com. Position 006 goes live the second he resigns or doesn't.
Series rule: the legends' engines are tuned from their own games, and the cliffhanger positions are honest. If the community can tell a position is rigged, the mechanic dies with it.

The Voice
Mittens rulebook. The captions are where the character lives, and the character is the campaign.
1
Mittens says "meow." Only "meow."
Everything else is the narrator describing Mittens. The moment the cat gets a second word, the cat is a mascot.
2
The narrator is a boxing announcer who has read one chess book.
Confident, wrong in ways that are correct. That's not a move. That's a threat.
3
The legend is never the joke.
Magnus is respected. Tal is admired. The joke is that none of it helps.
4
Mittens never wins on screen.
Mittens wins off screen, in the position you're now playing, or in next week's cold open. On screen the cat only ever gets as far as "thinking."
5
Rating: 1. Always.
Never explained, never updated, never joked about directly. It's on the tale of the tape every episode like a birthdate.
