why most of chess players are fond of cheating against their opponent

Sprinting and marathon, they are virtually the same race. That's why all the top sprinters are great marathon runners and vice versa.

Pinheads and Blockers are joined at the hip as well.

Haha please, you're just bad. You're also a disgusting honorless bitch, I've just played you and you let time run out after blundering your queen.

thats not true, moron! you can check it out in my allprevious. I havent do such coward and useless things like you did! you are more than honorless bitch you said! you are maleducated pathetic creation.xD:

I doubt anyone's cheating in blitz games. There's simply not enough time to run all those moves through an engine. The reason you don't improve is probably because you play nothing but blitz.  Nothing but blitz is bad for your chess development. Try playing longer, or even correspondence/daily games with some regularity.

Why do people always say this?  Engines are standalone from UIs in chess.  How difficult do you really think it is to write a browser plug-in that plays live chess on chess.com for you?  The answer is:  3 man hours.

There are boatloads of blitz "bot" cheaters playing every day.  The newer bots are probably a lot harder to catch and are not so braindead as to automatically select a top-3 engine move, just clearly winning moves.  People that think they are avoiding cheaters by only playing blitz and bullet are sorely mistaken.

Yep this clown can't handle the fact that he/she/it has been beaten.  Was perfectly fine with rematch after a win.  As soon as I beat this whiner I was accused of cheating.  Typical of someone that can't progress and figure out their opponent.
