The previous winner of the Candidates tournament, Sergey Karjakin, may have been at the bottom of the standings by the end of Round 6 when he scored just 2 points out of 6 games, or a -2 win/loss record, but he came out strong after that, winning 4 of the next six games, including his Round 12 win against the then leader Fabiano Caruana.
Wesley So was holding a drawing position towards the endgame against Sergey Karjakin, until he ran into time trouble and blundered on move 35 with 35.. Ke8. Karjakin was with a winning position when So lost on time.
Vladimir Kramnik may have started the Candidates Tournament 2018 exceptionally strong, as he scored 2.5 points in the first three games. Yet, he scored just 0.5 points in the 3, as he lost his Round 6 game against Shakhriyar Mamedyarov. Mamedyarov then joins Caruana in the top of the standings.
Meanwhile, after losing his first 2 games followed by 3 draws, Wesley So finally won a game in this tournament, at the expense of Levon Aronian.
FIDE’s Candidates Tournament 2018 is an 8-player, 14-game, double round-robin tournament featuring the select top players of the world to compete against each other, the winner of which will claim the right to challenge the throne of the World Champion Magnus Carlsen.
Vladimir Kramnik may have taken sole lead by the end of Round 3, but Fabiano Caruana defeated him in Round 4 to grab the lead from the former.
Levon Aronian may have experienced a setback in Round 3 as he lost to Kramnik, but gained grounds as he defeated the former challenger, Sergey Karjakin, in Round 4.
Chess.com has recently developed a tool that evaluates the strength of play for any chess player, or the quality of moves of any chess game. They call it the Computer Aggregated Precision Score (or CAPS).
Essentially, what CAPS does is evaluate a player’s game (or set of games) and assess its moves for its accuracy against what the computers think are the best moves in each given position.
Now, since world champions of different eras have no way to prove their worth against each other, CAPS is a good way to evaluate and compare the quality of their games, and thus will give us a “rough estimate” of how well world champions will fare against each other should they face over the chessboard.
