!? The Traxler Gambit, a very sharp opening, Black is willingly sacrificing material for a speedy attack on the enemy King.

White could have chosen the more stable Bxf7+ winning just a pawn but also keeping some initiative whilst destabilising the Black King.

6.Kxf2 Nxe4+ is uncomfortable for White e.g. 7.Kg1 Qh4 8.g3 Nxg3 9.hxg3 Qxg3+ 10.Kf1 d5 and Black at least forces a draw.

Grabs the material advantage and removing any Rf8 possibility.

8.Bxd5 falls for Bg4 winning the Queen

Renews the Bg4 threat

Gives the White Queen the a4 square, also hitting the Knight

Black has two pieces hanging in the position, however if 11.cxd4 there follows 11...Qf6 12.dxe5 Qf4 and the attack on the King is too strong.

This, therefore, was the only move and had in fact been played 40 times on RHP before this game.

Qf6+ is also an option but Qh4+ instead pulls the g-pawn forward, so White loses grip on the f3 square
