Lichess Puzzle Rush

I created an app over 10 years ago and sent that off to chess.com in late spring 2018 for a new chess app/game competition they were running with Jennifer Shahade and Danny Rensch as judges. I didn't win but my app was used as inspiration for Puzzle Rush.

Why on God's earth haven't we got the Puzzle Rush format on Lichess already.

The puzzles go from lichess.org/training/1 to lichess.org/training/125272 it is not difficult to write a simple script to keep score and time the solving sessions for 3 minutes to 5 minutes.

Alternatively we just put blitz tactics on Lichess. blitztactics.com/

I've got no axe to grind I just love Lichess and I hold the copyright for this format of puzzles so if copyright infringement was the issue, it shouldn't be because nobody can claim copyright except me and I won't because I made the app free for everyone to use.

My issue with chess.com has always been that when I sent Danny Rensch the code he made in unrestricted for subscribers only instead of free for all.

Let us get Puzzle Rush/ Chess Master Cube/ Blitz Tactics on Lichess for Godsakes!

I feel like many people would think that lichess copies from chesscom

chesscup.org/
Free puzzle rush which seems to be based on Lichess puzzles.

@Bishop1964 I am one the developers at the admin team of chesscup.org/ :)

@classictactics true but chess.com copied from me, they literally took my app code I sent them and made a clone and renamed it.

Sounds like them. Crappy site.

Sorry I don't know much about these things, but couldn't you sue them for using your code for doing something without your consent? @michuk

Did the competition state that chess.com could deliberately use your code? if so, I don't see why you are complaining.

ultimately, it's up to the lichess staff. There have been petitions, other forums, all asking for puzzle rush, but it doesn't seem like it's happening. (At least not yet)

Why make a puzzle rush here if you have chesscup.org/? Free, derived from lichess... there's no need for it here.
