Doesn't Vishwanathan Anand only see three moves ahead? I read somewhere that he does. Well, I can see more than like ten moves ahead sometimes more. That's what I mean when I say Elo rating isn't everything. You can't just measure ability and talent with a rating.
So anyway if I played Anand all I would need to do was go through every since variation on the board and if I had enough time on the chess clock and since I could see more moves ahead than him I would hypothetically win that game
Anand can certainly see farther than ten moves ahead, if he needs to.
I mean, you have to remember that Anand is a former World Champion, and has been one of the strongest grandmasters in the world for several decades.
Realistically speaking, there's probably nothing about chess that you can think of that he hasn't already thought of himself, or tried.
When Grandmasters talk about looking only 3 or 4 moves ahead, they're talking about being practical, and saving their heavy calculations for when the position calls for it.
And a lot of the times, looking past 3 or 4 moves isn't really needed. Especially if the objectively best moves are obvious at a glance.
Probably because they were played against weak players. In world championship matches most of the openings are e4 or d4. Bad openings like c4 or g3 are rarely used in world championship matches
