Version 2.7.1 (Bug Fixes: Checkers, Chess, Theme Restore, Labels)

Khon’s Chess - Version 2.7.1 (Bug Fixes: Checkers, Chess, Theme Restore, Labels)

This release is all about tightening the bolts. A handful of sneaky logic issues were causing incorrect moves, weird win states, and unreliable theme behavior. 2.7.1 fixes the core problems and cleans up the board UI.

Fixed
• Checkers capture bug
• Corrected jump move calculation so captures and multi-jumps behave properly
• Checkers win handling
• Normalized winner values so endgame results and prompts trigger correctly
• Chess attack detection
• Added a dedicated attack map (no pawn pushes, no castling) to make check and castling logic reliable
• Prevents false attacked squares from pawn forward moves and avoids castling related recursion edge cases
• Theme restore on refresh
• Saved theme now reloads correctly and syncs to the Theme dropdown
• Board labels UI
• Rank and file labels are now anchored to the square corners for consistent placement

Notes
• No gameplay changes beyond correctness fixes - this is a stability and accuracy release

Quick test checklist
• Checkers: confirm captures and multi-jumps work
• Chess: confirm check, checkmate, and castling rules feel correct
• Refresh the page: theme should persist
• Labels: a-h and 1-8 should stay pinned in the right corners

Version 2.6.2 (LinkParams Theme + Game)

Version 2.6.2 – LinkParams Theme + Game

This release adds deep-linking support so Khon’s Chess can be launched in a specific theme and game mode using a single shareable URL. Ideal for festivals, events, kiosks, and QR codes.

New Features

• Theme via URL

  • Launch with a preset theme using ?theme=SFIFF
  • Example: http://petesimple.github.io/khonschess/?theme=SFIFF

• Game Mode via URL

  • Launch directly into a specific game:
    • ?game=chess
    • ?game=checkers
    • ?game=backgammon

• Combined Deep Links

  • Theme + game together:
    • http://petesimple.github.io/khonschess/?theme=SFIFF&game=chess

• Shorthand Theme Support

  • Theme-only shorthand URLs still work:
    • ?SFIFF&game=chess
  • App automatically normalizes to the explicit format

URL Syncing

• Changing Theme or Game inside the app updates the URL in real time
• Makes links copy/paste-ready for sharing without extra setup

Improved Save Handling

• Game state is now saved per game mode
• Chess, Checkers, and Backgammon maintain independent saves
• Switching games no longer overwrites progress in another mode

Event & Festival Ready

• Enables one-click launches for branded experiences (e.g. SFIFF)
• Ideal for festival lounges, lobby kiosks, QR posters, and social links

Internal Cleanup

• Safer initialization order when loading from URL parameters
• More robust reset logic when switching games
• Version bump and labeling cleanup
