Only when they're sandbaggers or they're not *that* low rated, or they're using an engine (some 1300 I played in unrated rapid lol).
In your case, it's none of the above. I know he/she was only an 1100, and played pretty horrible moves, but playing 3 seconds/move in a 15+10 game is giving your opponent a huge advantage, and even an 1100 can spot a mate in 1, given 20 seconds or so.
Time management! I always use my time in rapid games that I don't want to lose
Craaaaaaaaaaaaaaaaap
I recently hit 2000 in my blitz,
and in my standard, i lose a game to an 1100!!!
granted it was a hanging checkmate I failed to spot, but still, it's terrible...
do you ever lose to people reeeeeeeally low rated?? plz share
