About this extension

Turbocharge lichess.org with a ton of features

Read the publisher’s full description

This extension adds a lot of extra functionality to the https://lichess.org web site. Main features: - Extended Interactive Lessons allow you to play ALL variations - Explorer Practice allows you to play against the moves in Opening Explorer, essentially helping you train against any rating bracket on the Internet or a specific opponent - local computer analysis chart when no server one exists, even when not logged in - Enhanced PGN Import in Analysis board allows you to merge multiple PGNs into a single one (lichess limitations strip down the comments, but I am working on a solution). This helps you quickly collect a player's repertoire and maybe save it as a study Interactive Lesson, simulating their play. Then you can export the current analysis moves into separate lines as well, or just copy a single branch as a PGN. - See evaluation of possible moves of the selected piece in analysis - Automatic detection of interesting/brilliant/good/best moves - a PGN editor supporting a lot of operations and accepting tens of megabytes of text - Mobile device features (for browsers that support extensions on mobile, like Kiwi), including drawing arrows and circles on mobile, scroll/zoom lock while playing, etc. - Change the friends box into a menu or a button, live update Friends page, - Sound and voice notifications where players you follow start playing (with mutable option per player) - TV enhancements: Current games section for players you follow and streamers, menu to go to previously opened games, previous two games in player TV just like in category TV - Ctrl-right/left to play a random move from the available ones in the list. This also works for moves coming from transposing positions - Extra context menus for Analysis/Study move list. One allows you to copy the current branch as a PGN. Another will use add comments with the computer evaluation to the terminating moves in all branches - Show player country flags and game opening names - Custom piece sets, sound themes and board images There are many more. Here is a comprehensive list, in the order of implementation: - randomly play one of the next moves with Ctrl-RightArrow - configurable probability to play a move by putting prc:<number> in the move comment, where number is a percentage between 1 and 100 - highlights for the last move of variations in the analysis/study board - also showing which of the last moves that have not ended in mate have no comment - highlights the transpositions to the current move in the analysis/study board - also an option to show all transpositions in the PGN - play multiple variations in Interactive lesson mode in the same chapter!
