In both games we saw White trying hard and taking too many chances, way beyond the point where he had serious winning chances. This is one of the things that distinguishes this tournament from other top tournaments (besides the absence of rapid games), all the players want to win. There is only one real prize and the rating gain or position in the overall season and all of these things fall away. This is what FIDE tried to achieve with the Grand Prix in 2019, but the knock-out format only pushed the risk taking into the rapid stages of the tournament. Obviously there are a lot of Giri jokes floating around. I am maybe more guilty than most. But I want to be serious and say that Giri is one of the most interesting players of our age. He has great openings with really deep ideas. His positional feel is worse than none. His technique is excellent. He has problems winning won positions, but on the other side he is hard to take down, fighting like a tigress defending her cubs. This game can be divided into four phases. In the first phase, Giri delivered a novelty and Nepomniachtchi had to find his path. In the second we had a sharp middlegame where both players could make mistakes, as many options appeared and none of them were too clear. Eventually Giri got into trouble and decided to give up the queen. Then there was a third phase, where the fortress should have held, but where Giri made a number of poor decisions before the time control. After the time control the endgame was lost for White, but it was still difficult for Black to convert the advantage.} 1. Nf3 Nf6 2. c4 c5 3. Nc3 Nc6 4. d4 cxd4 5. Nxd4 e6 6. g3 Qb6 7. Ndb5 Ne5 8.

Rb8 31. Bxe6 Rxb3 {[#] We have reached the third phase of the game. Giri has given up the queen and should now find the right strategy. Had he chosen to play for a fortress immediately, I think he would have been successful.

Add to this that Nepomniachtchi spent only two minutes making this decision.} (43... Qc8 $1 {to advantage the pawn without tactics was a different path to the win. Only a high degree of certain that the fortress could be broken justified "winning" the bishop. However, there is another possible explanation. Nepomniachtchi is potentially the most confident of the players in the world elite. And we are talking about a lot of confident guys! Sometimes too much confidence translates into banking on luck. And luck paid the dividends today! If you look at the post game interview you will know that Nepomniachtchi had more certainty in his decisions than the objective evaluation of the position.}) 44. Rxf5 Qe1+ 45. Kg2 Qxd1 {[#]} 46. Rg5 $2 { This is the final mistake of the game.

[#] It is well-known that White would make a draw with the rook on e3 and pawn on f2. Black is even allowed not only one, but two h-pawns, and the fortress still cannot be challenged. However, once the pawn is forced to leave the second rank, a series of zugzwangs should decide the matter. The change from this conventional endgame knowledge is the presence of the pawn on h4. Without it Black wins trivially, even if it will take a long time. With it, matters are quite complicated indeed and I would personally have enjoyed watching the Russian trying to put White into a decisive zugzwang. It can be done, but it is incredibly difficult. I have here given the line that is best play from a human standpoint, not a standard tablebase line. Black's win is long and non-obvious.} 48. f3 Qxa2+ 49. Kg1 Qd2 50. Kf1 Qh2 51. Rg4 Qe5 52.

It is my favourite sporting event of all time and sadly only happens every two years. I hope you have enjoyed the annotations to this game and will enjoy what we have coming for you in the days to come. I will try to offer a different perspective than you will find in the various online commentaries, which hopefully will satisfy you to forgive me my Emperial spelling, which I have informed the editor is a non-negotiable condition on my part.} 0-1
