I rarely delete save files from games – I usually just move them to a folder – and while analyzing various types of cheating, I found a game without any labels (so it wasn't clear who was playing against whom). After reviewing all the save files up to 132, I came to the firm conclusion that the red player was cheating! I started trying to remember what game it was, and I was horrified – the red player was me :D. Recalling the events of that game, I realized that I was playing late at night, trying to lose as quickly as possible, and making completely absurd moves that turned out to be the only correct ones on that map. From this, I concluded that not everything that looks like cheating actually is ;) Before accusing someone of unfair play, take a look at your own save files – don't you find anything strange?
As for the issue of fighting cheating... well, what can I say? You have to catch them in the act! That's the only way – and loudly shouting and putting up shame posts, in my opinion, is nonsense.
