I have this opening listed as "Russian Game: Karklins-Martinovsky Variation."

Even though the -25 centipawn computer score is not very compelling, in actual game outcomes, it seems to have fared very well for black.
The humans and the computer also agree on Nxe4, with 100% compliance all around.

I am watching the current World Chess Championship 2018 and this Variation was played. I think I will just call in the Nightmare Variation. :D

Can you post the PGN when the game is over?

I love wild games.

Especially since this opening has a propensity for opposite castles, which I adore.

Full of threats and danger, and a piece up at the end (to a pawn) for Caruna. Carlsen was the one living dangerously in this game. King shelter shattered early and down a piece in the endgame, but escaped with a draw.

I haven't done a deep look but I think Carlsen was ok out of the opening. He got in big trouble later.
