Chessical: Johner soon after played the Black side of what was then cutting edge theory:Tartakower vs P F Johner, 1906
The game is hard fought. Johner plays very aggressively from the start, and it is clear he is going for a K-side kill.
Soon it seems Johner has burnt his bridges by over-doing his K-side ambitions <12.g4?!>, but Gattie is rather too cautious to capitalise on this. There was no need to retreat his R on the 17th move either R(a)f8 or Rc8 was much better.
Similarly <21...Qxb2> was powerful, Gattie seems transfixed with Johner's build up of heavy pieces on the K-side and ignores his own opportunities to attack.
<24.f5!?> is a speculative pawn sacrifice which pays off. He does not want a Black N powerfully ensconced on <f5>.
Gattie allows Johner to regroup on the K- side.
<26...Be8?!> is a waste of a move, the Bishop belongs on <b5> to support a Q-side attack.
<36 or 37...Rxf6> is equal, as played Johner is able to crash through to victory.
