Ask HN: Why are chess problems attack oriented?
13 by A_No_Name_Mouse | 14 comments on Hacker News.
I'm trying to get better at chess by solving chess problems on Chess.com and Lichess. All problems seem to be attack oriented, not defence. As a result in a chess match I constantly look for ways to attack my opponent, not to prevent an attack from my opponent. Why are chess puzzles not 50% about spotting and preventing attacks? Any advice to train that specifically?
