Some games are like deliberate suicide chess!??
Good one charity work lol 😆 yes I have had this on chess.com and another site I play on!? had great game tight a curate opening, tough muddle game, games one wants to play!! Then the next 2 games I was exchanges, pawns and odd Bishop up all within first 12 moves!!? Perhaps he was playing in the sauna and steam played a part ;)

That sounds like either the person is sandbagging or they suddenly have to quit and are just suiciding the game. I don't know...
you should see it at a 2000 level i do the same thing but tactics but at 1300 level its charity though attack is the best defense.
it could be sandbagging or cheating i know people who cheated just to brag that they are 1300(they aren't even that good) maybe 500 ish maybe they just decided not to cheat. either that or they like humor and charity.
