I don't think it's only opening theory which continues to evolve with each generation.I think that the understanding of how to play every kind of position improves with time,at all grading levels.
This in no way detracts from the achievements of the earlier pioneers of the game.Lots of people know how to build aroplanes today,and students can absorb all there is to know about relativity,but that doesn't mean that there wasn't something special about the Wright Brothers or Einstein!
However,if you had to ELO rate the quality of the Wright Brother's aeroplanes then they might only be 2200 compared to todays 2700 rated jumbo jets.
Furthermore you can't say with total confidence that,were you to bring the brothers back today,to this very different environment,and update their education,they would again be designing the best aircraft. Neither would Roger Bannister speed up and again be the best miler,or Rod Laver compete
with Nadal if you gave him a 2009 Racket - well, not Fred Perry anyway.
Nobody can dispute that the great names from the past were highly talented,but chess inevitably evolves,develops,progresses continually,as of course it has to,as we climb on the shoulders of each previous generation and add to the sum total of knowledge and understanding.
Perhaps somone can help me with this one? How many chess players were there on the planet in eg the days of Capablanca? And how many serious as opposed to casual players were there? I suspect that there was a considerably smaller number in both categories than there are today,and so perhaps being the most talented player in the World in 1926 may numerically be about the equivalence of being the most talented player in Australasia today. The game that Alekhine was talented at in 1930 was so underdeveloped that it bears little resemblance to the sophistigated game that Topalov and Anand play today,so much so that even if you gave Alekhine 10 years to grasp all the modern concepts,it may in any case be beyond him to calculate as well as Topalov and Anand,who have forged their way to the top in a climate in which more than a million players strive hard to play as well as they can.
Surely nobody can deny that,back then,outside the top few players,the standards fell away very quickly. The standard in depth today is phenomenal by comparrison. Ok I will cede the point that Capablanca and Alekhine were a fair bit stronger that 2200 even by today's standard of measurement,but I suspect that,by the same measurements,the world number 100 today and in 1930 would rate at something like ELO 2635 : ELO 2050.
And this leads me to my final point: I am constantly reading about ''ratings inflation''. I guess it can be proved mathematically that there is a bit of inflation in the system - eg 0.5 is always rounded up,stronger players benefit from the 350 point rule,unrated players come and go thus feeding points into the system,etc etc... There is however no inbuilt mechanism in the rating system to recognise the overall rising standard of play throughout the world.
Let me explain what I mean by this: Imagine that the entire chess world consisted of 10 talented ambitious young players who each had a rating of 1800.Month in month out they would play tournaments against themselves,and work out their new ratings after each tournament.A player's rating would always be rounded up or down to the nearest 10 points,but If a player's rating came to exactly eg 1845 then it would be rounded up to 1850.Ten years went by until they had played about 100 tournaments together.The average rating of the players had crept up to 1850.People began whingeing about ratings inflation,and how 1900 didn't mean what it used to mean. Mathematically this is quite correct of course, but after fiercely competing together for 10 years they had EACH GAINED an average of 400 POINTS in playing strength! This invisible truth didn't show in their ratings of course.
This is how I see ''ratings inflation'' in the context of the average overall rising standard of play throughout the chess world,aided by computers,internet chess,easy access to new and old information,growing numbers of active players(eg from the old Soviet Union and China) and so on.
