White got quite a normal performace with 3.Nf3, but it played it slightly under half the time and did poorly with 3.Bc4 and 3.Nc3.

White only won 2 of the 90 games.
1-- It began quietly but black sacrificed the exchange with 10...O-O, which did not work out in the long run.
2-- The strange 3.Nc3. White stayed a pawn down from the opening.
Although it did not have Syzygy and black did (an experiment of mine this event) white won in the ending. [Event "G/6'+2'' 4GBh Sy50mrOff"]
