This might be better posted in Pagination vs. "More v" control -- V2 was much better in this aspect than V3. thread.
In any case, there is a workaround: the URL of the second page is
https://www.chess.com/tournament/live?page=2
Just replace "2" with a good guess.
For example, this:
https://www.chess.com/tournament/live?page=200
takes you a week back, while this:
https://www.chess.com/tournament/live?page=2000
goes back to mid-March and this:
https://www.chess.com/tournament/live?page=20000
goes to mid-March, 2013.
For lists with this many items, navigation by date would be much preferable, though
i'm trying to find a live tournament that was played a few weeks ago... when i look through the list of completed tournaments, i have to scroll to the bottom only to find that i can advance by just a single page at a time... Seriously?
