Max Lange Gambit, after 5.d4!?
I have posted my notes on Movsesian - Adams, Corus 2009, which features two Super-GMs slugging it out deep into the theory of the distinctly 19th Century Max Lange Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.O-O Nf6 5.d4!?) I was not surprised to see this line revived, even at the highest levels, given recent analysis by GM Lev Gutman in Kaissiber #22 through #25 (discussed here) and GM John Emms in Dangerous Weapons: 1.e4 e5 (which I reviewed here), both of which nicely acknowledge my own contributions in "The Modern Horowitz Variation of the Max Lange Attack." As I indicate in my notes to the game, all signs point toward continued interest in this variation and the related Max Lange Attack.
