Less opening recall, more position evaluation
An unfamiliar arrangement makes automatic play difficult. From the start you must inspect weak squares, bishop routes, queen safety, and development order instead of replaying a memorised sequence.
Every position has an index
The arena uses the established set of 960 arrangements and displays the current position number. Draw a new one or return to the same index to compare several plans from an identical starting position.
Castling finishes on familiar squares
After kingside castling, king and rook finish on g1 and f1; after queenside castling they finish on c1 and d1, with matching squares for Black. Transit squares must still satisfy the safety rules.
How to read the drawn position
- Locate the kings and rooks and identify castling directions, then check which pieces block one another from developing.
- Compare each side's urgent needs: development, central control, queen safety, and whether a pawn advance can create an immediate attack.
- After the game, return to the position index and try another plan instead of treating one result as the final verdict.
Draw and play without an account
Guests can draw positions, choose a bot and colour, and play with Chess960 castling support. An account is needed only for permanent statistics and saved progress.
