What was white's plan around the point of his 12th move?
Far be it from me to second guess what was on a GM's mind but it looks like White was trying to extend the influence of his dark squared bishop towards g7 from around move 10-19, including the occupation of e5. The knight went via f2 and d3 and the queen via e1 to g3 supporting e5 and also looking down the g file with maybe Kh1 and Rg1 also in mind at some point. A hypermodern strategy of controlling the centre with pieces rather than occupying it with pawns and an attack down the g file in the back pocket. Maybe his position lost its integration once he had to play fxe5 and his knight not really contributing on a4, although he still had sufficient faith in it to launch his attack based on the pin of the black knight on d4 and potential weakness of g7 via the 7th rank.
A really interesting game!
