idk, based on your stockfish reports, seems like it, but you need a mod on this forum to really give you an answer.
IS THIS GUY USES ENGINE? LETS SEE !
He's got a really strange way of playing, I clicked on one of his losses. It was very weird:

Generally anyone below 2000 is NOT using a chess engine.

I agree with mrsnckl. I am new to the site and played barely 20 games. I play 1500 rated opponents and I do expect them to make at least a couple of mistakes and at least a single blunder 40% of the time. That what I do. But a couple of games I played the opponent was consistently making very solid moves. They were not making mistakes at all. If they really play like that they would be winning regional OTB tournaments. What are they doing hanging around on a website with 1500-1600 rating?
It really takes a few seconds per move to get an engine assitance so I expect that many a player here are not above such cheap shots for a little ego boost :)
Btw, in lucaantoniob89 (1720) vs. hamisimsek (1666) game the culprit missed trying to fork black king and queen by exchanging bishops around move 15. This is something a live player would certainly go for, while an engine might see further and prioritize creating more economical mating threats. Does this prove anything? Of course not. And what is the point of banning him? He will open a new account in the next 10 seconds.

These kinds of threads about cheating aren't allowed in the forums. You can take this kind of thing to the Cheating Forum group. Or since you've already done the engine checking yourself, and it seems fairly conclusive, just sent in a report. https://support.chess.com/customer/portal/emails/new

That's plain wrong. Just have a look at the discussions in the Cheating Forum, and you'll see plenty of U2000 players banned for cheating.

You would think not.
BUt so many of the games I lose online look a lot like lucaantoniob89's games, fairly obviously played by a computer or with computer assistance. I might be wrong about 1 or 2 but that is all.
As to the analysis using stockfish, unless mrsnckl is talking crap, which I severely doubt, its absolutely decisive.
Bad news is it is incredibly common. Perhaps because it's so hard to enforce.
Spare a thought for the victims of Borislav Eljanov. He cheats in otb tournaments and his opponents are professionals trying to make a living. He is rated around 2300 and must be one of the best known players in the world of that rating. His mummy must be proud.
Guys, this thread is 3 months old. The staff already banned the account.
Looks like he was playing games yesterday though...

To be honest, the game you provided seems very logical from his standpoint.
In most cases, before I saw what the continuation was, I asked myself what I would do, and it was the same as what was played.
Rest is not a proof, or even indicative, that that was engine.
Now, here lies my thesis - when moves are logical, statistics you provided can be misleading. 0 mistakes, 0 blunders, 0 strategical errors is not that perfect if you are in forced sequence of moves or in situation where moves are fairly logical.
Haven't checked his other games, and let's be clear, I AM NOT saying that he EITHER CHEATED OR NOT CHEATED.
Just sayin' that for these cases, you need more than what you have provided as proof.
BTW, if you are interested in cheating with engine, check out kingscrusher video on Borislav Ivanov (Chess cheating scandal in Zadar open). Very instructive (there's also a video on it by Valeri Lilov and few people who take the opposite standpoint)

@joyntjezebel: I think you mean Borislav Ivanov, not Eljanov. We wouldn't want people to start distrusting Pavel's legitimate super-GM progress. He's currently a half-point behind Caruana in the Tata Steel tournament in Wijk an Zee.

Yeah.
Also, B.Ivanov doesn't cheat... should be past tense.

No one plays consistently with such accuracy, its humanly impossible, hes a pumpkin eater for sure. I thought li*****.org, (we gotta pretend that it doesn't exist here right) had a system for naming those who used computer assistance, if you hover over the persons name it becomes visible whether or not they have used computer assistance.

Yeah.

Only because he doesn't currently play. FIDE excluded him from their ratings list back in January 2014 and initiated ethics commission proceedings against him, which seem to remain unresolved.

"Only because he doesn't currently play" is a pretty good reason to make it past tense lol.
He was also banned by his federation... although I'm not sure what that entails.
It all started with my desire to play one(1) 15|10 standart game. It was a nice day, i get up and set my otb and put the computer against me. While i was putting the pieces i was looking for someone to play at same of my rating. And there was a guy who came and changed EVERYTHING!
Listen up, i dont really a kind of person who blames everyone that he loses. I lose a lot, i mean A LOT and i kind of like it too. But when someone tries to make me fool, now im not that cool.
There is the game i recently played against the player that i suspect about (if he uses engine or not)
Okey, i had really little time to calculate variations at the last 10 moves, so i dont think i made a good job. I never thought he was using machine while i was playing with him. Even after h6,g5 i thought he was making a rookie mistake. But when i finished my game and went to analyse it i was kind of FROZEN.
I made the analyses from another chess site whose using stockfish as:lichess
Not making any kind of advirtisement i just wanted to share the analyses with you guys
http://en.lichess.org/ccAVL1Xz#22 ==> ANALYSE the game
6
Average centipawn loss
He/She has 0 inaccuracy,0 mistake ; okey 0 blunder is quite normal but acl is 6: It seems like an engine at the first place, but i didnt want to make any calls prejudice.
So i went to check his other games, lets see if its something special for me or it was a machine issue ?
Okey i went to see his last game before me, and checked this. I suppose his opponent wasnt really in his mode and went down pretty quickly. And when you analyse this game too you can see that:
lucaantoniob89 (1727)0Inaccuracies 0Mistakes 0Blunders 6Average centipawn loss
albertomanuel (1691)3Inaccuracies 2Mistakes 0Blunders 30Average centipawn loss

ALRIGHT, little bit suspicious ha !? You have to admit, it might be an engine ! So keep looking on his last games.
I mean personally, when i saw this game i decided that he was cheating. I was sure about it. Cuz checkmate in 12 moves, didnt even miss 1 move !

He is so good ha!? alright.. He had much much much more games like that. you can check his passed standart games.
Why i made a big deal about it ? Just 1 game ha ?
When i saw this issue, i went to live chat room and asked for assistance about these stuff. And i wasnt really being welcomed. Because some guys said "Noone gonna care about who is cheating in some 1400 rated players game"
And his nickname was "Xion447" im sorry but im gonna show him because he was really insulting me while i was trying to tell the issue.
After of my couple insistences some guys checked the game, and all they were saying was "No cheat ya suck! (Lets go and grab some beer dude mode)"
Xion447: Forever, i scanned the guys game, she made several blunders and the opponent didnt see them at first..not engine at all
Xion447:.Noone gonna care about some 1400 rated guys cheat claims.
The Funny thing is, my standart rating is higher than this guy. LOL
Some other rude guys were talking about some stuff too but i dont want to share all the chat.
So, what do you think; is this guy using an engine or not ?
