Here is a 20|0 game played here on
chess.com and what I took away from it.
What I learned: When playing aggressively when you have an advantage or are up material it is important to keep up the iniative. In other words, keep making threats, keep the heat on. By trading down the attacking pieces you naturally begin to lose the ability to make threats. As seen with the Knight sacrifice on move 18 and the queen trade on move 20.
HOWEVER, if you're up material and the end isn't clear for you, by all means, trade down and make things easier for yourself.
Question of the Day: Do you think it's okay to keep playing pressuing and aggressive moves even when the end isn't clear or concise?
