here for example is a known B class player ( OTB ) that is a pawn up against a well known GM ... the GM is 2600 FIDE but here the B class player is also 200 points higher rated than the GM !?? Who thinks this B class player ust suddenly improved a lot ?!
Naa, "edward hunting" is probably just his alias. Besides if the guy was doing what you're suggesting then chess.com would ban him promptly.
I don't have enough information to express a judgmental opinion, but a club player playing at GM level at turn-based chess is suspicious, to say the least. But to balance this view, even before chess computers were at all strong there were correspondence chess specialists who were unknown over the board. In the (interesting) linked game, I feel Qb3 was a very natural move forcing the win of a pawn, so the loss of the pawn can be said to be a pawn sacrifice by the GM on the previous move. While to more average players, the risk of his knight being trapped could be missed, I doubt a GM playing turn-based chess would miss the danger. I don't claim to be strong enough to assess whether this gambit is sound or not.
Well, after the move a3 in the opening, I can tell the extraclass 2700' is not using a computer. He need it now though. 
Besides, Julio sacrificed the pawn, he didn't need to. It could be justifiable because the open line b and the long diagonal, like a benko gambit. Besides, I know he likes this kind of challenges (we were mates at the same sport school and we shared the same coach). I will follow up this game.
Anyway, what is this thread all about? I have not read the whole thing. Who will be the pious soul to show me a shortcut?
Just because a bunch of people were banned in the past doesn't mean anything about this group.
Looking at your list I notice a guy like Gonnosuke... are you trying to tell me that after over 1000 games of alleged cheating that chess.com hasn't banned him? Preposterous.
Ah yes, Gonnosuke, AKA Roy Gates. Rated about 2000 OTB, yet ahead of all titled players in turn-based here.
Yes I have analysed Gonno, once with Deep Rybka 3 & once with Houdini 1.03a multi-processor engines. Others have also analysed his games.
I have no idea why he's still here, tbh.
I believe I could tell you why he's still here.
In my previous account, I got the chance to play Roy several times (15-20 at least). In most of these games, he was able to give me instructions and explanations that significantly exceeded the level of a 2000 player's understanding of chess.
I was also informed that his '2000' rating was from tournaments that he played 20 years ago. That's 2 DECADES ago. Slightly out of date, don't you think?
I also recall that his chess.com rating used to be in low 2000's when he was starting out here (which seems fairly accurate). I recall a steady increase in his rating over a couple of years - and his quality of play and understanding seemed to increase as well. The amount of time he spends on games (over 1000 of them, plus puzzles that he plays out and sometimes posts here) leaves me understanding how he could be a very strong player.
I wouldn't be surprised if, at this point in time, he entered several tournaments and came out with an IM designation. But hey, a hobby is a hobby.
It always amazes me that some people can be so gullible.
Mortzy was banned for cheating. Apparently he was using a very strong engine . Gonnosuke played Mortzy 31 games , winning 22, drawing 9 and losing NONE. There is NO way to explain such a result other than one centaur beating another centaur.
