The 2018 Chicago Open was won by Monday Begins on Saturday and Sunday Comes Afterwards, consisting of Matt Bollinger, Shan Kothari, Adam Silverman, and Matt Weiner, who beat A Dead Meme isn’t Art (Ike Jose, John Lawrence, Jakob Myers, and Andrew Wang) in the first game of an advantaged final. It was the first CO since 2012 in which a team did not clear the field.
Due to a Chicago room reservations problem, the tournament was held at Northwestern University in Evanston, leading to endless "Evanston Open" and "Chicagoland Open" jokes. Reed has advocated for returning to the title "Virginia Open" as a compromise.
The tournament had a mixed reception, partly due to still-excessive difficulty (somewhat harder than 2016 while being substantially easier than 2017). In particular, the decision to ask directly about a number of authors and works from minority groups, and the decision to make the arts distribution 1/3 non-European were seen as major contributors to the heightened difficulty, often negatively impacting playability.
