One match commentator noted that Trump had won earlier in the week and now the Norwegian champion was using a similar-sounding method.

"It will be known from now on as the Trump-owsky Attack," one waggish spectator quipped.

Apparently Carlsen's own family recognized the similarity:

Despite his hat tip to the victorious Trump, Carlsen only managed an agreed-upon draw after 42 moves with Karjakin.

Trump raised the hackles of a number of American chess players last month when he incorrectly claimed that the United States does not have any grandmasters, the highest level of players in the royal game.

Trump even managed to get the term wrong when he said, while criticizing the difficulty of the nation withdrawing from multi-lateral trade agreements, "you can't terminate — there's too many people, you go crazy. It's like you have to be a grand chess master. And we don't have any of them."

In fact, the U.S., with 90 grandmasters, has the third largest number of players with that title in the world out of all nations.

Friday's was the first game of a match that will run through the rest of the month in lower Manhattan at the FIDE World Chess Championship. Carlsen, the 25-year-old defending champion is the favorite against his 26-year-old Russian challenger.
