I play Philidor defense, Lolli attack, Fried Liver attack... Other people choose to play well known openings/defenses, so i decided to ask the following questions.
Everyone learns the Najdorf defense because it scores well. (or because Kasparov and Fischer played it). The Philidor isn't as popular as other defenses on the other hand. I have a few questions about that:
- if you wanted to know how well an opening/defense scores, is there an online database that keeps track of all the games ever played and gives you the overall rating of an opening by calculating the average score, or do you take for granted what other players told you?
How to know if the Najdorf for example is a good opening, maybe Fischer and kasparov won, because they are good players, not because the opening is good. Same question about bad opening and defenses, I mean in the middle game if the player is bad, no opening will let him win, I mean how much can you memorize? How many variations? At some point you have have to rely on your intelligence.
Don't good openings become bad opening when they become well known? I mean lets use the Najdorf again as an example, because everyone wants to learn it, it is so well known, doesn't that make it a bad opening? The opponent will be well prepared for it.
- And lastly, is it better to play openings/defenses that score well (French defense. Indian etc..) or is it better to play an opening that is not well known and that your opponent didn't learn?
