Perfect games can happen, rarely. Usually on short and highly tactical games like this one. I've played exactly one in my life (plus another where an engine running on the Fritz 10 GUI won't flag my one error since it merely thinks of it as "departing book").
So treasure it; it won't happen often, and it's awesome when they do.
@calculator According to the computer, he did, in fact, play perfectly.* What's impressive is not that he won, but that he played the best move each time. Surely most people would have played a second best but "good enough" move somewhere?
*I do wonder whether 2300 is enough to determine whether the game was actually perfect or not. That's barely stronger than even a regular master. I tend to think 3300 is far closer to perfection...
Thanks for your comment! I agree that chess.com computers are not perfect, but I was wrong about the rating. After a quick check, I see that the rating of chess.com computer analyser is actually ~2500 Elo - like a strong IM or maybe even a GM.
In recent years I have played more than 2000 chess games on chess.com and many other websites. I used to be a 1600's player in the past. In fact, this is the first time in my life that I play a game without making mistakes. Like you say, it's very rare so I hope you enjoy the moves :)
Hi guys
I just played my most accurate game ever.
I checked every move in this game with Chess.com computer analysis (Rated 2500). The computer said that I made 0 mistakes and 0 blunders. This is surprising because my rating is only 1050! I didn't know I could play like this...
