Sicilian Four Knights at Aeroflot 2019

In a recent daily game my Four Knights repertoire was tested to breaking point, following a theoretically-critical game all the way to move 27 before an unfortunate and embarrassing double-blunder meant that the game lost theoretical significance.

The theoretically-critical game in question was Wei Yi - Fier, Aeroflot 2019, which contained a stunning positional queen sacrifice from the Chinese GM and led to his victory in fine style. After my daily game had finished I went to check whether Black had any improvements to repair the line, and it seems that the game should be drawn with best play, although this does not detract from Wei Yi's beautiful idea.
