And here Nikolic failed to find the only defense against the threat 26…Rd4!: 26.Rxd8 Rxd8 27.Qh4.

Ivan Cheparinov-Daniil Dubov Turkey 2014 White to move
23.e5! dxe5 24.f5! e4 25.fxg6 fxg6 26.cxb5
26.0-0-0 looks like the normal follow-up. After 26…Nxg5 27.hxg5 Black is practically forced to play 27…Nh7, leaving White with a clear plus. Now the game becomes tense again, until Black overlooks an immediately decisive blow.
26…axb5 27.Bxb5 Nxg5 28.hxg5 Ng4 29.0-0-0 Nf2 30.Bxe8 Qxe8 31.Bc3 Nxh1 32.Rxh1 Ba6? 33.Ng4! Be7 34.Rxh5
Yes, the pawn can be taken en passant. Which is practically forced, as Black is threatening to capture on h3. A bishop sac on g2 is also looming. 22…Kd8 23.Qe3 is less clear (23.Qxf7? Rxh3).
At the cost of another pawn, the king has found a safe place. All Black’s other pieces are pointing at the white king. White is utterly helpless.
Here the 1997 Junior World Champion slips up. He could have reached the desired better endgame with the cunning 30…Bxc6 31.Nxc6 Bf4 32.Bxf4 Nxf4 33.Nxd8 (33.Kf1 Rd7) 33…Ne2+ 34.Kf1 Nxc1 35.Nb7 Rc2.
