Chesstempo seems to have two pages for database display.
This one works at random: https://chesstempo.com/game-database.html
Sometimes it shows the moves in sequence of most usage and then the probability of WDL. Other times it shows nothing.
This one seems to work all the time: https://old.chesstempo.com/game-database.html
What is the difference between the two databases?
Does that 'old.' refer to the database or to old code to display the database?
It seems to me that the 'old' UI works right and the new one is full of bugs. Or is there some other features I am missing. Still need an answer to the related question here.
