I enthusiastically recommend Chess Tempo (https://chesstempo.com/), which will give you interactive chess puzzles from real games that are tailored to your level. Someone else mentioned the similar system on lichess, which is also fine. - Source: Hacker News / 7 months ago

Does anybody know? There was a post from two years ago about this, and someone commented chesstempo.com, but I can't find the same board there. Source: 9 months ago

I use chess.com to play and I also have an chesstempo.com account which seems to be really good for practicing the openings. Source: 10 months ago

To get better at #2 pattern recognition, work on fast tactics. Go to chesstempo.com and train with blitz/easy tactics. Do this every day. After a time, I think you won’t need to do the Fritz training (maybe a month or two and you should be good), but do the tactics everyday. It’s your daily vitamin. Source: 10 months ago

Then, in about 1993, I remember Chess Genius playing a strong player at a tournament in Hammersmith and, despite general confusion on the board, it slowly advancing a rook's pawn down the board; it eventually became a Queen and the opponent resigned. That was a watershed. Source: almost 2 years ago
