Sparring
Nine partners from beginner to engine. Each one plays its own openings, and the strength is set on the engine itself, not faked by dropping pieces.
Pip
800
Just learned the rules and is very excited about the queen.
Grabs material, forgets the king.
Hazel
1000
Solid opening moves, then improvises.
Develops properly and castles early.
Otto
1200
The London System, every single game, no exceptions.
Structure first. Will not be provoked.
Vera
1400
Sicilian as black, Italian as white. Knows her lines eight moves deep.
Sharp, principled, punishes loose pieces.
Bruno
1600
Trades into endgames on purpose and grinds you down.
Technique over fireworks.
Kestrel
1800
Attacks the king with everything, sound or not.
King's Gambit and Dragon. Bring a helmet.
Juno
2000
Positional python. You will not notice you are losing.
Catalan and Caro-Kann. Squeezes.
Orsa
2200
Calculates further than you and knows it.
Whatever the position demands.
Sigma
2500
The engine, unleashed. Nobody has beaten it yet.
No mercy, no book, no mistakes.
