September 10, 2018 was a record day for chess geometry. At the World Junior Championships, there were two games with totally closed full files on the board after 24 moves. I had never seen them exist later than the opening. In the strange sort of coincidence that long-time readers have come to expect on this page, on the same day at the same tournament, there was also a game with a rare, full rank. All three games are below.

CONNECTICUT CHESS MAGAZINE
Connecticut Chess Magazine and Coventry Chess Club are each philanthropic enterprises by Rob Roy.
They are not governmental initiatives nor are they business endeavors.
They are private initiatives by Rob Roy, for the public good, focusing on quality of life, and on chess in Connecticut.
They should never be misconstrued to represent the State of Connecticut, the Town of Coventry Connecticut, nor with any other chess associations.
The monthly tournaments in Coventry are conducted by Rob Roy acting as an independent organizer, and not by any chess club, state chapter, nor federation.
I have never written for, nor spoken for, anyone besides myself, Rob Roy, acting as an independent chess journalist.
Rob Roy derives no material gain from these two entities, in contrast; Rob Roy suffers significant monetary loss from their operations.
