Play Chess Against a 900 Elo Computer
Greta is a 900 Elo computer opponent from Germany with a tidy, low-risk style. She builds a safe Queen's-Pawn setup, keeps her pieces defended, and waits for you to overreach. She won't hand you free material the way the beginner bots do — you have to earn the win. Free, no account, straight in your browser, with a free review the moment you finish.
What a ~900-rated opponent plays like
Greta develops sensibly, castles, and rarely leaves anything hanging. She isn't hunting knockout tactics; she is happy to trade into a safe position and let you make the first mistake. Where she slips is ambition — she misses the deeper tactic, defends passively, and can drift when the position needs an active plan rather than a solid one.
Against Greta, tricks alone won't work; she answers the obvious threats. Beat her by building real pressure: improve your worst piece, open a file, and create two threats at once so a solid defender can only meet one. Patience is the tool — she will hold a simple position, so you have to make it complicated in your favor.
Who should play Greta
Greta fits players around 750–1050 who can already avoid one-move blunders and want an opponent that makes them play chess, not just spot hanging pieces. If Zara's tactics feel too sharp, Greta's calmer style is a good stepping stone. To win, out-develop her, take space, and convert small advantages patiently into a winning endgame — exactly the technique the free review will show you where to sharpen.

Frequently asked questions
Why doesn't the 900 bot hang pieces like the beginner bots?
Because Greta is built around a solid, careful style — she keeps things defended on purpose. Her mistakes are subtler: missed tactics and passive moves, not free pieces. That's what makes her a genuine step up from the 400–700 bots.
Does a 900 bot play like a 900-rated human?
In strength, close. In style she is deliberately solid, so she may feel steadier than a human at 900 who takes more risks. Treat the number as a difficulty level; the calm personality is Greta's own.
