A 1-point lead
Things were looking great for Ian Nepomniachtchi after five rounds at the Croatia Grand Chess Tour event. The Russian had finished day 1 with a comfortable 2-point lead, and had kept his commanding lead in the first two rounds of day 2.
Nepomniachtchi started the day with a win over Alexander Grischuk. The World Championship challenger used a small trick to gain a pawn.
22.Be4 With a threat that Black ignores.
22…Be7 [22…dxe3 23.fxe3 Rdc8 White is slightly better with the bishop pair.]
23.Bxc6 Rxc6 24.Bxd4 This was the intention. White has won a pawn. Now follows the technical conversion.

In the fifth round, the leader drew Jan-Krzysztof Duda. His immediate pursuers were Maxime Vachier-Lagrave and Viswanathan Anand. Vachier-Lagrave had beaten Duda and then drawn Ivan Saric. Anand drew against Shakhriyar Mamedyarov and then defeated Anton Korobov in a difficult game.

In the last round of the day, however, Saric put a stop to Nepomniachtchi’s undefeated streak. In a long theoretical variation in the Sveshnikov — up to move 23 there was still a predecessor — a rook-and-bishop endgame ensued, in which Saric had a small advantage with the black pieces, thanks to his control of a half-open line and the more active bishop.
23.Ke2 Rab8 24.a3 g6 25.h5 Kg7 26.Rh3 Rfc8 27.Kd3 Kf6 28.hxg6 hxg6 29.Rh7 The rook is not well placed here.
29…Rc7 30.Be4 Kg5 31.Ke2 [31.Kc2]
31…b4 [31…Kxg4?? 32.Rg1+ Bg3 33.Rxg3+ Kf4 34.Rh4#]
32.cxb4 axb4 33.a4 b3 34.Kf3 Rb4
35.a5 Rxe4 Temporarily gaining a piece. In the end, it is actually an exchange sacrifice.
36.a6 [36.Kxe4 f5+]
36…Rd4 37.a7 e4+ 38.Kg2 Rxa7 Black has to give back a rook, but he als0o gets a passed pawn on the b-file and a few extra pawns.
39.Rxa7 Rd2 40.Kf1 Rxb2
41.Rb7 Kxg4 42.Rh8 Be5 43.Rhb8 Rb1+ 44.Kg2 b2 45.Rxf7 White is still resisting, but it will not be enough.
45…Rd1 46.Rfb7 Rxd5 47.Rb4 Kf5 48.Rf8+ Ke6 49.Re8+ Kd7 50.Reb8 Rd1 51.R4b7+ Ke6 52.Rxb2 Bxb2 53.Rxb2 d5 54.Rb8 d4 55.Rg8 Kf5 56.Rf8+ Kg5 57.Re8 Kf4 58.Rf8+ Ke5 59.Re8+ Kd5 60.Rg8 d3 61.Rxg6 d2 62.Rg8 Kc4 63.Rd8 Kc3 0–1
