cheating discussions are not allowed
Then they probably didn't cheat. I feel the cheating trauma has caused many to overthink things especially when they lose. If the account was made more than a year ago, then I think you can trust it 99% of the time. If it is within a month, then it is a bit suspicious. Making 5-7 good moves isn't a big deal especially if the moves actually makes sense in the position. Anyways, ask such questions in the cheating club or whatever the mod is about to say soon.
