Christopher Yoo in Fantasyland

In the eighth round of the US Chess Championship young Christopher Yoo uncorked the seldom played Fantasy variation by moving his f-pawn one square on his third move. Word on the Chess street is seeing the move onscreen caused GM Ben Finegold to have a conniption fit.

Seeing the move made this Chess fan smile. Unfortunately, the offbeat openings played ‘back in the day’ do not see much action these daze, so when one is essayed it is a special treat.

I began putting the moves into the analysis program at Lichess to only look at the opening moves. Next thing I know I was in the middle game and “just had” to know how the game would play out, so I opened Hearts of Space (https://v4.hos.com/this-week/program) and listened while watching the game as time stood still for quite a while.
