Playing blitz

Pros:
Allows you to try out your opening variations to evaluate their power
Improves your split-second decision-making
Improves your time trouble skills

Cons:
By playing fast, you are not considering key and deep moves
Playing incorrectly isn’t always punished
Speed chess is insanely addictive
In the long-term does not improve your chess level
