happened to me too but only because people let me win and then they stopped letting me win ;) just kidding happens all the time. rankings isnt 100 percent accurate and dont forget, someway on their way up rising people must necessary play against higher rated people who they crush.
you never know maybe they were like 1600 players in the making. it can have several reasons, just enjoy chess..
May be is me that is playing so bad but since a few weeks ago, low ranking players seem to be playing pretty good. I don't know but i was in the 1400 range and now i'm in the 1200!. I don't think i'm playing worst than before (i hope), but i remember to be able to beat a 1200 with no problem, now i'm struggling.
Is anybody else experiencing the same? Or it is just me? should i give up on chess?
