After 46...Be5, it is White to play and NOT to draw! Stockfish one of the strongest free engines and at a adepth of 34 suggested the natural looking 47.Bd5 with a slight advantage for White (+0.6). Indeed I would come up with such a move in this position but only with draw in my intention. However, Naka played the brilliant and totally unexpected 47.g5!! Stockfish, which could not find this move on its own, gave White a score of (+1.69) after playing 47.g5. There is always room for human creativity! Here is the PGN of the game. Enjoy!
