About 1LK
1LK_v2.4.895
Turn every Chess.com game into a more immersive, expressive and memorable chess experience.
1LK enhances Chess.com with custom audio announcements, realistic chess clocks, cinematic game effects, performance controls, enhanced Game Review tools and a beautifully redesigned handwritten tournament scoresheet.
During live games, 1LK can react to key moments such as game starts, checks, time scrambles, draw offers, rating differences, openings, streaks, flags, wins, losses, draws and special achievements. Its intelligent audio queue helps announcements play in the correct order without unnecessary overlap.
Choose between a realistic DGT digital chess clock and a traditional analogue chess clock, both designed to fit neatly above the board and remain readable at compact sizes. Adaptive Performance Mode helps reduce unnecessary background activity, with additional controls for Bullet games and lower-powered systems.
After the game, the standard move list can transform into a realistic paper tournament scoresheet featuring:
handwritten-style moves and move numbers
paper texture, ruled lines and tournament details
occasional human-like corrections and strike-through marks
your real handwritten signature
an opponent signature rendered from their Chess.com username
1LK also expands the Game Review experience with Brilliant-move effects, accuracy announcements, missed-checkmate detection, cinematic replay features and Review This Moment diary entries. Saved moments can be revisited through the 1LK Diary Library, complete with notes, images and voice recordings.
