There was a game I played once that was theoretically perfect. I set up an early mating attack after 1. e4! for which there was no defense. Here it is:
Which game do you consider as your best game? [SERIOUS REPLIES ONLY]
Or this one, where I beat my opponent by discovering an early queen sacrifice. Now they call this the "legal trap" because my Dad is a lawyer. It may not be as perfect, since there opportunities for black to avoid it, but queen sacs are very fun!

10 or 12 years ago I was really into 1 b4, and found a really hectic line. I spent hours on my pc looking for lines. A few times in league games opponents fell into my prep, and I had this, plus a few similar. I'm still pleased with it, but a few weeks ago on here I forgot the move order and lost badly against Savage :)

What's your best game, MSC?
Lots of opening preparation here, I think, until move 22. I sacrificed many pieces to come to a won endgame (well, not so obvious). I quite struggled to win it, but I still think it's one of my best games so far.

@MSC157: In the first simul that I played with you we had an interesting Najdorf and when I entered the second simul I had the idea to play it again. However, I had just played a game in the Pin Variation and was a little bit worried if that was a problem for the open Sicilian. Therefor did I try to play that against you.
In the pin variation I had lost a pawn after the opening was over. In the end game I decided to play actively and sac another pawn. The result was that his two pawns advantage became two isolated pawns at the a file. After that he had to fight for a draw in a rook ending and he was two pawns up. He managed.

This game was from almost 2 years ago, but I still think it's one of my best games. :)
Also, because I have a video on chesskid.com of it that you probably cant watch because you probably dont have a membership :/

Not a particularly well-played game, but a very tense and exciting one; in which White's last-ditch counter-attack barely fails to break through and mate me.

This was my best game on chess.com online chess, I liked it because I was able to get a good position against a good player, even when I was a bit scared of being smashed after I saw Ng3:

Wow, it's difficult to pick just one! I guess the game where I beat my first master in correspondence is a strong contender, so I'll post that.

It was 1|0 bullet, but I feel like it was my best game in my life. I agree there was lots of intuition, but still...

This is the first time that I won a 5 minute game. I got a checkmate.

hard to pick! ah i have one, although MSC157 will not fondly remember it.
i don't quite remember the ratings but i worked really hard to win this game. It is only fair to note that i lost 2 games before this and two after though i did win a 60 min standard game. (it was late for him i believe)
so we have 4-2=0 for him.
I mean the game you've played. It can be either OTB or Online chess game. Name reasons why is it you best one - because of tactical shots or perhaps due to its aesthetics...
EDIT: "Serious tab" - do not post opening traps, widely know, unless you played it against GM.
