perhaps whoever is playing let someone else play that was more experianced? its weird.
I think someone is using an engine.
I looked at your game and there is not enough moves to know if somebody is using an engine. Also, none of the moves have been that hard to find. I think your just blowing your lead instead - maybe you should report that :)
In fact your pin move was quite tasty because it was a pin threatening checkmate which is harder to find in my opinion. I think your a bot and I'm going to report you!
After looking through a broad sample of your games, I can't find a single one that suggests you're not a fool for posting this. Nobody has made any moves that are startling in deepness of thought, and you're still overwhelmingly ahead. Now stop crying and get back to work.

The thing is that if he was positionally good enough to cripple my pieces the way he has, he should definitely have been good enough to see the pin (which, by the way, wasn't THAT hard to find, because the king is in the middle, and the queen is misplaced). Also while I agree that the individual moves weren't that hard to find, the way he combined them for a plan to immobilize me is inhumanly precise. That is what got me suspicious.
I just played through the 12 moves of your game...Are you kidding? How are you "immobilized"?
You're looking at the game where his opponent is 300 lower rated and simply dropped a Q with no pin. Look for one with rating difference almost 200, and more moves.
If I got that game identified correctly, the accusation of engine aid is utterly wrong, but since the game is in progress, I don't think it would be appropriate to explain why.

Thank you, LegoPirateSenior, and I agree with you on it not being appropriate
sometimes people get an adrenaline rush when they're losing, but if your opponent is down a Queen, you shouldn't be complaining, even if you lost.
Sean_The_Pawn, my recommendation to you would be to not worry at all about this topic. In your rating range, this topic is negligible, and you will get much more fun and learning out of your games when you do not waste any thoughts or worries on this topic. 
I swear someone I am playing against is using an engine, or something. I am currently rated 200 more than my opponent. In the game I won his queen using a fairly simple pin tactic. Soon after, he started playing positionally brilliantly, the kind of play I would only expect from a master. Either he somehow shot up 800 points in rating overnight, or he is using an engine. How do I report this?
I will only add that rating and illegal computer assistance are inversely proportional. You can draw your own conclusions from that.

Remember, it is correspondence chess. I've had games that have lasted half a year, so the moves vary in quality a lot. Also, as others have said, the moves your opponent played were not amazing at all, even for that rating level.
^I believe it would be impossible to use an engine in 1 0 chess, you'd just flag.
Sean the pawn if you would like, I will evaluate that game with an engine of mine to show you that your opponent has not been playing perfectly(I am almost 100 percent sure I wouldn't need an engine to show you where your opponent went wrong).
i'd be interested in the results. What engine are you packing, fella?
