wwall: Edward Winter sources the game from Wiener Schachzietung, July-Aug 1912, and says it was played May 7, 1912 in Vienna. White was F. Munz.
Instead of 19.Bd7, perhaps better is 19.Bc4, and if 19...Rxb2 20.Rab1 Rxb1 21.Rxb1 Ne7 22.c6
Instead of 26...Bxg2, perhaps 26...Ndf4 first, then 27...Bxg2.
After 26...Bxg2, White could try 27.Ne3 (instead of 27.Qg3 as in the game and seems to be the losing move), and if 27...dxe3, then 28.Qc4+ Kh8 29.Nf7+ and White wins. Also, 27.Kxg2 may be playable. If 27...Nh4+, then 28.Kh1 Nxf2+ 29.Rxf2 Rxf2 30.Kg1 Rg2+ 31.Kf1 Rxh2 32.Nb7 wins for White.
Or 27.Kxg2 Ngf4+ 28.Kg3 f5 29.h4 Nh5+ 30.Kg2 Qxh4 31.d8=Q+ Qxd8 32.Qe8+ Qxe8 33.Nxe8 and White may be able to hold for a draw.
