wwall: This can't be Heinz Wirthensohn. He would have been 4 years old in 1955. Barden and Heidenfeld says the player is Wirtz. Another source says it is Wirth.
7.Kg1 is more common in this Traxler variation.
8.Nxh8 is probably better than 8.Kxe4.
If 11.Qe1, then 11...Bf5+ 12.Kf3 Nd4+ 13.Kg2 Bh3+ 14.Kg1 Qxa1 mate.
Or 11...bxc6 12.Qe1 Bf5+ 13.Kxf5 Qf4+ 14.Ke6 Qf6 mate.
If 12...Bxc6 not 13.Nxh8? Qf4+ 14.Ke2 Qf3+ 15.Ke1 Qxh1+ wins. Better may be 13.Rf1 O-O 14.Nc3 Qxh2 15.Qg4 Rxf7 16.Rxf7 Kxf7 17.Ne4.
If 13...Bxc6, then 14.Rg1 O-O 15.d3 Rxf7 16.Qe1 Bf3+ 17.Kd2 Qf4+ 18.Qe3 Qxh2+ 19.Kc3 looks OK for White.
If 14.Ng5, then 14...Bg4+ 15.Nf3 Bxf3+ 16.Kxf3 Rf8+ 17.Kg2 Qf2+ 18.Kh3 Rf3+ wins for Black.
If 16...Qg1+, then 17.Ke2 Qxh2+ 18.Ke1 Qh1+ 19.Ke2 Qe4+ 20.Kf2 Rf8 21.d3 Rxf7+ 22.Kg3 Qg6+ 23.Qg4 Qxg4+ 24.Kxg4 and White may hold.
If 17.Ke2, then 17...Qxh2+ 18.Ke1 Qh1+ 19.Ke2 Qe4+ 20.Kf2 O-O 21.d3 Rxf7+ 22.Kg3 Qd4 23.Nd2 Qf2+ 24.Kh3 Qe3+ wins for Black.
If 17...Kxf7, then 18.Qe2 Rhf8 19.d3 Kg8+ 20.Kg2 may be OK for White.
After 20...Rf2, Black threatens 21...Qxh2 mate. Another mate is 20.d3 Rf1+ 21.Qxf1 Qg4+ 22.Qg2 Qd1+ 23.Qf1 Qxf1 mate.
