The take of another (former) random blogger: Unpredictable as the whole thing is, it actually follows familiar scripts from former modern candidates. One of the leaders at halftime always cruised to tournament victory, never scoring more than +1 in the second half. A co-leader always collapsed in the second half, while someone with 50% or less at halftime was surging in the second half to get within striking distance at some stage. And the latest twist now for Ding Liren might be his second attempt to copy a player with partly Asian roots.

The data:

2013 Carlsen 5/7 + 3.5/7, Aronian 5/7+ 3/7 (but out of the race after round 12), Kramnik 3.5/7 + 5/7 [dramatic final round with Carlsen and Kramnik both losing and tiebreaks then favoring Carlsen]

2014 Anand 4.5/7 + 4/7, Aronian 4.5/7 + 2/7, Karjakin 2.5/7 + 5/7 (first place might have been within reach if he had beaten Anand in round 13, and he did have winning chances)

2016 Karjakin 4.5/7 + 4/7, Aronian 4.5/7 + 2.5/7, Caruana 3.5/7 + 4/7 (but tied with Karjakin before the last round, then losing against Karjakin - because it was a must-win game as tiebreaks favored Karjakin)

2018 Caruana 5/7 + 4/7, Mamedyarov 4.5/7 + 3.5/7 (not collapsing but still falling further behind), Karjakin 3/7 + 5/7 (tied with Caruana after beating him in round 12)

2020 becoming 2020/2021 Nepo 4.5/7 + 4/7 (though the loss in the last round was irrelevant as he had already secured first place), Vachier-Lagrave 4.5/7 + 3.5/7 (but definitely out of the race after round 11). Half-surging: Giri - from 50% at halftime to +3 after 12 rounds (clear second half a point behind Nepo) but losing his last two games. Surging: Ding Liren with 2.5/7 + 4.5/7 (only a footnote at the time, but affecting his Elo which eventually became relevant for the ongoing candidates event).

The collapsing player was almost always Levon Aronian - did he pass this propensity to his new countryman? Surging players were Kramnik (retired) and Karjakin (this time disqualified).

In 2018, Ding Liren (one win in round 12 and 13 draws) couldn't quite copy Giri's memorable result from 2016 - now he can still follow up on Giri's result from 2020/2021. The surging player could now be Radjabov: Will he beat Caruana after beating Nakamura and Ding Liren? And if so, will he still fall short of second place?

Names involved now were unpredictable. For starters, Caruana cruising and Nepo collapsing would have been more consistent with the reputation and track record of both players - Nepo seems fully aware of this, thus "safety first" for him in the second half. At halftime, people may have had Ding Liren on their list. Firouzja may have been on some/many lists - but the candidates is something else than beating sub-2700 players to qualify for the candidates and temporarily cross 2800. Who would have thought of Radjabov???
