Can we get a little love for the broke but dedicated?


Congratulations on your Legend status!
What you heard about chess.com leagues is true. There are currently no plans of hosting tournaments in the Legends club for prizes. I personally went several years with the default membership before getting premium, so I can relate to the progress and accomplishments.
I do lots of free puzzles on lichess and chessking app...then i do the 3 daily puzzles on this site as a 'final exam' since you know you don't want to lose points if you slip up

If you're serious about improving, you don't really need anything more than what's freely available ... The analysis board (https://www.chess.com/analysis) is an especially helpful free tool. I spend more time hanging out there than I do playing ...
The bots are great sparring partners, too. (https://www.chess.com/play/computer)
And the Opening Practice section (Learn -> Practice -> Openings https://www.chess.com/practice/openings) is a very helpful way to drill your openings against custom engine levels ...
You don't need a paid membership for any of these.
