I can’t believe chesstempo has no Wikipedia page. It’s like the greatest puzzle site ever.
Part1 – Unbelievably unique puzzle rating system.
Like chessc*m, lichess & whatever, you get your usual ( untimed ) puzzles. But chesstempo also has timed puzzles. And it’s not like ‘puzzle rush’ or whatever. The puzzle pool for untimed ( called ‘standard’ ) / timed ( called ‘blitz’ ) is the same, i.e. the puzzles, just like the users, have a rating for both untimed & timed. Expectedly, a puzzle or a user has a higher untimed than timed rating assuming the user really treats the untimed the way you’d treat a correspondence game if you’re really making notes and stuff rather than just playing ‘asynchronous live’ ).
Implication :
Your chess / 9LX rating is correlated more to your chesstempo timed rating than your chesstempo ( or lichess or chessc*m ) untimed rating. So, you can have expectations of your chess / 9LX rating based on your chesstempo timed rating.
The closest I’ve seen to chesstempo’s timed puzzles is ‘rated‘ in BlitzTactics.com. But yeah there isn’t like a corresponding ‘unrated’ rating. But hmmm…maybe there is some correlation between this rating and your chess / 9LX rating, so you can have similar expectations.
Part2 – Comparison to deathmatch & training in csgo / cs2 or valorant.
The analogy I see is :
- Aim / spray training = Untimed puzzles
- Deathmatch = Timed puzzles
- Your rank is correlated more to how well you’re doing in deathmatch than to how well you’re doing in aim / spray training ( however you might quantify these ). But obviously, the correlation between timed puzzles & chess / 9LX rating is much greater than the correlation between ‘how well you’re doing in deathmatch’ & rank.
Part3 – 2 things not in chesstempo that lichess has :
- ( regular chess only ) – puzzles by openings
- Puzzles by game phase ( opening / middlegame / endgame ) & endgame type ( queen endgame, queen & rook endgame, rook endgame, knight endgame, bishop endgame, pawn endgame, etc )
