You're not wrong. The specific comment I was replying to was just me pointing out how silly the term "chess bot" was in my opinion. Sure, there is software that when combined with strong hardware (among other things mentioned later) is close to impossible to beat by humans. But an important aspect thing about them is that they have access to many opening books and tablebases. Stockfish for example (the highest ranking chess AI) even has a voluntary "botnet" of people donating processing power for it to learn.
Hmm, yes, the term "chess bot" might seem to be a bit misleading; although to be fair, it's still accurate: chess programs aren't endowing the computer with any greater understanding of how chess is played - it's still mostly an automation task, where the computer is using brute force to check all the possible outcomes in any given situation (access to typical opening and closing moves doesn't change this; they're just another tool).
But more importantly, as I previously alluded to, and as Revelation Machine (now that's an original nickname
) pointed out as well, you don't really need strong hardware, or any other elaborate schemes, in order to have an already (close to) unbeatable computer opponent; a simple smart phone will do nowadays - in other words, anyone has access to them.
i am sure it will be not easy for some one to run a bot on this site. i wll keep capture each match and will analyisis players moves, and will make sign up system we hard so it will be not easy for a bot to log in in this site
I'm not sure if increasing the difficulty of signing up, and other such measures, is a good idea - they might end up making the site less useable, while not really stopping players from using their favorite chess program to cheat. But, perhaps analyzing player moves as you mentioned, maybe along the lines of what XinXan previously suggested, might help somewhat.
