Winning on time doesn't mean anything.
how did a 500 rated beat a WGM on chess.com ?

It's easy to only have a 900 rating; started as a 1200, lost the first game to what appears to be a disconnection and has only played 5 games in total.

What? Then what are those clocks for? Time is very important factor in chess, especially in blitz chess, its all about time management.
I meant it doesn't mean anything in terms of player skill or who was superior. Not online when you can't even know why she ran out of time. 7 minutes went by without her making a move. The position was dead even. I also think her opponent's rating was bogus.

@TRextastic his best win is only 1200s because when he got past the WGM she herself had a rating of 800!( not in real life though that is 2500) i am talkin about chess.com ratings.
LOL. it sounds more crazy that it is. i was going through the archives of a WGM that she lost to a 500 (it was a rated game) but later realized that the 500 was so slow that the WGM went for a sleep maybe. and he managed to win on time! LOLO

But grandmasters are grandmasters afterall she took her revenge by beating him in the next 2 games maybe she challenged him for a rematch.
