This idea that the databases somehow do the work for you and magically win games without one having to think is rather comical. If one normally plays bad losing moves in the opening, using databases merely allows you to postpone your bad, losing moves to the middle game. (Of course if your opponent insists on playing certain bad moves in the opening your database may just do the work for you...)
Grumpty seems to think that using chess engines is part of CC. This is ignorant. They aren't. Someone else mentioned that tablebases aren't allowed in CC, actually, in ICCF sanctioned CC tablebase are allowed. (BUT NOT HERE~! This is why people who've bothered to read and understand the rules of the game they purport to play refer to chess.com's turn based chess as modified CC)
Grumpty also mentioned keres and alekhine didn't have technological help -- well, they availed themselves of all the resources available, meaning all the published theory they could find. They played CC... and this all misses the point I'd been making, which is that it's absurd to think CC, as played today, harms a person's game turning them into a "paper tiger" --... there are today CC GMs who are also OTB GMs. Ulf Andersson, (highest rating 2625... he's beaten Karpov that's counts for something, eh?) is an active CC GM. There are many, sorry don't know them all. Consulting databases during a game does not harm anyone's skills any more than consulting databases does while training (which all OTB GMs do, rather a lot). Claiming CC use of databases harms your chess mostly reveals a lack of experience with databases -- IOWs talking about things you don't actually know about.
Chess means thinking... anyone who wants to avoid thinking is advised to avoid chess. Whenever I get lazy at the chessboard and make fast moves or don't calculate I remind myself that chess is for thinking and if I don't want to think I should find something else to do. Databases are a tool for thinking about chess. Sure, some dopes might try to use databases to avoid thinking, but they aren't going to get anywhere and no one needs to bother about them -- No one who plays chess seriously tries to avoid thinking if they can help it... not with databases, or chess engines or any other way... real chess players DO use those tools to think deeper. These tools, databases in particular let you get deeper into the game.
I honestly believe that the majority of people who puff themselves up saying "I don't use databases blah blah, it's not what chess is about blah blah" really, deep down, are saying, "I'm not up to this new challenge, I'm not up to having to learn how to use databases and deepen my thinking with them... chess is hard enough as it is" They aren't trying to improve or challenge themselves... they are being mentally lazy at worst, or, more generously, fearful of the new.
Exactly, and if you don't understand the moves you're making, you're just blinding doing what the databases say, they will drag you out of book right into their lair.
