i was playing bullet 1-0, winning easily with enough time for me in end game, and my opponent had only 2-3 sec left, and suddenly his time becomes 15sec left, i am 100% sure because i was watching his time.
i was suspicious also other times from other players, but this particular time i am sure because his time changed in front of my eyes!
anyway, i dont care at all about my points and my rating, but i think this player is at least ridiculous and destroying the joy of chess, specially speed chess and also bad influence for others.
i just wanted to let you know and ask if it happens to others, or if is something else.. I hope chess staff can succeed to resolve this kind of situations, for example when u look back the game, enable a time function, so that later it can proved and bann the player who cheats (for ever!!)
thanks, and keep enjoy bullet games!
a speed chaotic player.. :) noclass
