All of a sudden, Black is better.
28…Bc3 29.Rf1 Qe5?! If Black wants to have any chance to win, he cannot trade Queen. Unfortunately, he seems gun shy and opting for a safer continuation and throwing away his advantage.
30.Qf3 Lahno is playing aggressively, opting not to trade Queens.
30…Qf6?! Again, Negi is playing too passively. He either lacks the self confidence or match experience. He no doubt has plenty of talent but this is an area where he has to work on to improve.
31.d6 Qxf3 32.Bxf3 Rd8 33.Bxb7 Bxa5 This is not a good outcome after trading the Queens. Negi completely misplayed this strategical position. Now White clearly has a little advantage. Even though it is an opposite color Bishop endgame, the d pawn gives White small chances.
34.d7 Rc7 35.Bc8 Bb4 Black may just end up giving up a Rook for the Bishop and d pawn if given a chance. That would lead to a draw.
