Italian-Koltanowski gambit ((2 part series)

GM Boris Alterman responds to the many requests from ICC members to delve into very aggressive lines such as the Italian-Koltanowski gambit with 1. e4 e5 2. Nf3 Nc6 3.Bc4 Bc5 4. 0-0 Nf6 5. d4!? It looks like a complete throwback to a bygone romantic age of the 19th-century, but, surprisingly, two Super-GMs were slugging it out with it in the very modern setting of the Corus Wijk aan Zee tournament earlier this year, as Sergey Movsesian dusted off this forgotten variation to beat Michael Adams. Could it be a case of Back to the Future with this vicious line being brought back into praxis?
