While great fun, I don&#x27;t think playing blitz is beneficial in the long run.<p>It encourages plenty of bad habits: guessing (instead of calculating), &quot;gambling&quot; (making bold but refutable moves in hope that opponent misses the correct answer), over-relying on simple tricks like common opening traps which wouldn&#x27;t work and would get you into an inferior position in a serious game, etc. etc.<p>Good blitz players are good chess players who happen to put their skills to a use by playing blitz, but they haven&#x27;t developed these skills just by playing blitz
