It was a bit of turnabout is fair play in game 2 of the world championship match between Magnus Carlsen and his challenger, Fabiano Caruana. In game 1 Caruana was surprised in the opening and soon on the defense, despite having the white pieces, and had to hold the draw a pawn down in a rook ending. That same scenario characterized game 2, changing only "Caruana" to "Carlsen" and "1" to "2".
There were several disanalogies, however, that come out in a fuller account. First, Carlsen had the first opening surprise in game 2 - a mild one - in that he started with 1.d4 rather than 1.e4. Second and more significantly, Carlsen was never in serious trouble, while Caruana was completely lost for a time in the first game. And third, while Carlsen played the drawn pawn-up rook ending for a very, very long time, Caruana's "effort" was perfunctory at best, and the entire game went fewer moves than the portion of game 1 that consisted of Carlsen's flogging a dead (or at least mostly dead) horse.
It was a successful day for Caruana, who has probably vanquished any psychological scars from the first part of game 1, and can spend tomorrow's rest day worrying about his openings. He got nothing with White in the first game, and it remains to be seen if today's 10...Rd8 is a serious move that can stand the test of time or just a clever one-off.
Here's game 2, with light notes; the more detailed subscriber version (and video) will be sent out later.
