435152: 1) if a 1900 can't know if he's playing a computer ... what chance does a 1400 have? none.

2) Kasarov is most famous for publicly admitting to anonymously playing chess on the internet. big names like Karpov and Polgar have also done it.

You said: "computer won all the matches against human, not just by winning one single game" This is only a half truth. It is true that humans have been beaten in matches in the last several years. However, matches between computers and world champions have had by far more drawn games and are usually decided by one or two games.

It's becoming obvious to me that you are someone who knows quite a bit about Chinese Chess but almost nothing about Chess.

ColonelCrockett: the chance to know if you are playing against a computer, nothing to do with your rating. this is my answer to your incorrect statement (1)
just tell me how much better chance for a 2000, 2100, 2200, 2300, 2400, ........than a 1900 like you.

435152: "you said i know nothing about chess, i know more than you know."

I fail to see how you've come to that conclusion. We've never played that I can remember. I have several open game slots if you'd like to put all your cards on the table. This discussion is over from my end (because when facts and logic are ignored discussion is pointless).
