Magnus Carlsen and Hikaru Nakamura agreed to an early draw today in the third game of their World Championship match. A Queen's Gambit from Carlsen was declined by Nakamura via the Modern variation. With Carlsen up 1.5-0.5 in the match, he seemed to feel no need to press for a win, and Nakamura was also content to bide his time and await his turn with the white pieces. The game was drawn on the 18th move.

It looks like you are trying to describe the moves of a chess game between Magnus Carlsen and Hikaru Nakamura. However, the notation you provided is incomplete and it is not clear what moves are being made.
In chess notation, each move is recorded using the algebraic notation system. This system represents each square on the chessboard with a unique combination of a letter (a-h) and a number (1-8). The letter represents the column and the number represents the row. For example, the d4 square is the fourth column and the fourth row, while the d5 square is the fourth column and the fifth row.
To record a move, the notation includes the piece being moved, the starting square of the piece, and the ending square. For example, the move 1. d4 indicates that a pawn is being moved from the d2 square to the d4 square.
I hope this helps clarify the chess notation you provided. Let me know if you have any other questions.
