In the meantime, a 28-player Italian Game tournament has started, also at Chess.com. I am in one of four 7-player groups, and in my first 6 games I have black in 5 of them. Alas, the one game with the white pieces I have been unable to finagle a Jerome Gambit. (I am again exploring the opening line suggested by chessfriend Yury Bukayev.)
For the time being - until at least one game is completed - I will be Jerome-less in this tournament.
