I do not think that this will affect the current Carlsen - Caruana match for the world chess championship, but I think it could mean more fun for the average chess player.
Just ran across the Twitter feed for Urdu Chess (@UrduChess), "Chess News from Pakistan", that, in turn, links to the "Jerome Gambit Trap" at ChessOnly.com, previously mentioned on this blog.
It only stands to reason that if players are going to learn about the Jerome, they should start with the refutation. I'm just saying...
(p.s. I tried to explain the Jerome Gambit and this blog to a non-chess-playing psychologist the other day - quite unsuccessfully, as it turns out.)
