- A 7-year-old created a new chess-like game with unique piece movements: front lines move like a king, large circles move like a bishop diagonally, and a spiral piece (the king to be checkmated) moves like a queen.
- The user described the game to the AI model o1-pro, which generated a webgame version of it.
- The game tends to be drawish because all pieces are powerful, making it easy to trade pieces and reach a stalemate, but it is easy to make a mistake against a high-depth AI.
I made a Chrome extension to help avoid playing cheaters in chess

- Author created a Chrome extension to detect potential cheaters on chess.com by analyzing opponent stats.
- Cheating is widespread, especially at higher ratings (2200 rapid, 1900 blitz), with 3/5 rapid opponents suspected.
- Extension computes a risk score (0-100) based on winrate, account age, and high-accuracy game percentage.
- Chess.com's anti-cheating measures are ineffective; few reports lead to bans, and abort limits hinder fair play.
- The model uses a weighted mathematical formula, with configurable thresholds; code is open source on GitHub.
- Future updates may include scoring history, report tracking, and abort limit warnings.

- AttoChess optimizes by rethinking board display, move decoding, and search loop, saving 10 bytes.
- Board display draws directly to console using int 29h, eliminating render buffer and DOS function 09h.
- Startup removes BIOS mode-set, using deterministic assumptions and cld for smaller code.
- Input decoder folds constants into base address, using 16-bit pointer math and imul for efficiency.
- Search loop frees CX by comparing pointers, avoiding depth reload from stack.
- Pawn direction is folded into color bit with xor, handling both colors in one path.

- The FIDE Ethics & Disciplinary Commission (EDC) found former World Champion Vladimir Kramnik responsible for multiple violations of the FIDE Ethics and Disciplinary Codes.
- The violations included breaches related to dignity, respectful treatment, bullying, cyberbullying, psychological abuse, and failure to cooperate with a Fair Play Commission investigation.
- Several other charges, such as those concerning integrity, honesty, and reputational harm to FIDE, were dismissed due to insufficient evidence.
- The EDC emphasized that combating cheating is a top priority but must be handled through confidential procedures with proper evidence, not public accusations.
- Kramnik received a two-year ban from FIDE competitions, with the final 12 months suspended for a three-year probation, resulting in an active one-year suspension if no further breaches occur, plus 12 months of unpaid community service.
