It's concerning at this point
We all saw how Gukesh won the Candidates and then defeated Ding in the final classical game to become the youngest World Champion. This year in November, Gukesh is going to defend his title against Javokhir Sindarov. On one hand, Sindarov is in red-hot form and playing great chess, but on the other hand, Gukesh is trying his best, but the results are not coming in his favour. We wish to see Guki back in his form!

Pranesh M vs. D Gukesh (1-0)
Playing with the black pieces, Gukesh decided to go for the Caro-Kann defence, and it turned out to be a great decision as he completely outplayed Pranesh in the opening and got a huge advantage. Pranesh found incredible resources to keep his king safe, launched a fearless counterattack, piled on the pressure as the clock ticked down, and won the game.

Arjun Erigaisi vs. Nihal Sarin (0-1)
This game was a great example of endgame technique, and you can check out the endgame analysis by none other than GM Dr. Karsten Müller. Nihal stuns Arjun Erigaisi with a brilliant victory. A result that could prove decisive in the race for the quantbox Chennai Grand Masters title, Arjun now sits half a point behind Alireza and must defeat him in the final round to keep his title hopes alive.
