The longest chess game in history

Here is the longest chess game in history, between Ivan Nikolic and Goran Arsovic. https://www.chess.com/a/AcdmqHMG2Ck3Y

The game truly was masterful, with such an amazing and flawless endgame. Of course, there was some mistakes I found after analyzing this game myself. Move 22, when black played g3 was definetely not best, but, Qh5 is crushing. Also, on move 50, black played Bg4, and instantly relieved white of the pressure. After that, the game continued with outstanding endgame skills displayed and ended in a draw. There is certainly a lot to learn from this game so take your time with analyzing this, I hope you all have a nice day!
