Exact URL of where the bug happened

Steps to reproduce the bug

1. Open Lichess on a mobile browser (iOS Safari or Android Chrome)
2. Enable blind mode
3. Start a new game or analyze position
4. Navigate to the chess board area
5. Try to explore squares by moving finger across the board
6. Attempt to read all squares in a rank (e.g., from a8 to h8)

What did you expect to happen?

Expected Behavior

• The entire 8x8 chess board should be visible on screen at once
• Users should be able to explore all squares by moving their fingers across the board
• Screen readers should announce square names as fingers move across them
• Continuous exploration of ranks, files, and diagonals should be possible without scrolling

Proposed Solution

1. Add a "Full Screen Board" button that when pressed:

   • Expands the chess board to fill the entire screen
   • Ensures all 64 squares are visible and accessible
   • Maintains essential information like clocks and last move
   • Similar to how physical chess boards allow continuous tactile exploration

2. Add a "Collapse Board" button to:

   • Return to normal game view
   • Show move history and other game information

What happened instead?

• Only a portion of the chess board is visible at once
• Have to scroll horizontally to see squares on the right side of the board
• When exploring a rank (e.g., 8th rank), only squares a8-d8 are visible initially
• Must scroll right to access remaining squares (e8-h8)
• Constant scrolling makes it impractical to maintain board awareness
• Cannot efficiently explore the board as one would with a physical chess set

Operating system

iOS latest

Browser and version (or alternate access method)

safari

Additional information

• This feature would primarily benefit blind and visually impaired players using mobile devices
• Current blind mode works well on desktop browsers with arrow key navigation
• Mobile implementation should maintain similar accessibility standards as desktop version

Environment

• Platforms: iOS (Safari), Android (Chrome)
• Input Method: Touch with Screen Reader

Impact

This enhancement would make Lichess more accessible to blind players on mobile devices, allowing them to play chess on-the-go just like sighted players.
