Andy Soltis just wrote a column is Chess Life about the rise of American English useage in chess over recent years; supplanting British English, and German during Steinitz and Lasker's time.
But I think it positively wierd how many IMs and GMs, when interviewed, manage to get in the words "Well OK,..." You name the originating country, and you'll hear it. I even heard British GM Michael Adams say it a few weeks ago. Was he trying to imitate the Russians?! They're the main proponents (like Kramnick), but you'll hear it in spades from Carlsen, Topolov, Aronian. The only guys resisting are Anand and Svidler, who are both so fluent in the American idiom that they are beyond it. In fact, Svidler sounds as American as a Ph.D candidate from the U.S.. Impressive. Anand speaks very fast English, while also speaking fluent Spanish.
