The match is half over, and it's tied, 3-3.
But today's game was full of drama! (As 538 put it, Chess World rattled as someone nearly wins game).
Caruana, with the black pieces, managed superbly to create a passed central pawn, and Carlsen was forced to sacrifice (?) his knight for 3 black pawns to eliminate it.
Caruana then won back two of the pawns and was, more or less, a knight ahead.
Carlsen then sacrificed a third pawn in order to get his king locked into a corner of the board in such a way that Caruana was a in danger of making a stalemate, and then, while maneuvering to try to break through, after 6 hours of play, he allowed Carlsen to force the draw.
So, there we are. What will the second half of the match bring?
