This is sad and i feel for ye on this. OTB is where it's at. i'd limit chess with him to OTB and no other way.
Cheating

Well that sucks. The games are pretty suspicious, especially the one where you used a moderately strong engine. I've never seen a beginner control themselves from taking a free piece...

how old is your cousin if you guys are like below 20 or 18 then it's like ok both of you will grow up , i'm not saying it's ok to cheat but cheating is childish and you can grow out of it

you guys are kinda grown up but lol but still childish from what i see just confront him laughing about the whole subject if my best friends lies to me i try to understand why and just forgive him and if it needs a confrontation i do it laughing about the whole subject like you cheated you little **** why don't you learn how to play and then come playing me ! , trash talk him back laughing about it like you didn't even care , you guys can still be friends if he is a decent person everyone makes mistakes , the part that really sucks that he bragged winning that's just a bad trait to have in general even if he didn't cheat lol so it's your choice what do you want to do with it , so my advice is that you don't even care and if you want to confront him do it in a laughing matter and rub it in his face gently too lol
To be honest, if you knew he was cheating, you shouldn't even tried to use an engine just to win, althought I understand the situation, it makes you almost just as bad as your cousin.

He just wanted to be sure if his cousin was cheating. If his cousin blunders, then he knows he is not cheating and he can stop using his engine


yea, that happens if the cheater gets caught
