No. f3 is the signature move in the Yugoslav. It supports the g4 advance.

Ouch!
2 other 2000+ players have played Bf5 (Mega 2012) 28 games in total with this move

I am not familiar with that one, but I still think I remember f4 being played
in the Dragon at a much later stage, of course.

Do you have any objections to me analysing 20 of your games from 2011 which have more than 20 or more non-database moves vs 2000+ rated players & publishing the engine match rate results in this forum?

I've done that already, but i'd be interested to see how your results would compare with mine.

The one flaw I see in all of this analysis stuff with Rybka, Fritz or whatever, and saying Kasparov or other top masters matched up with a less percentile then certain players here do is that these masters were not playing Correspondence Chess.

With Correspondence Chess you essentially have a adjournment after every single move with all the time in the world to study the next move.

In Correspondence Chess you have no pressure. You have access to all kinds of material. Books, internet, etc, on the latest lines and such, before you make the next move. Unlike the Great masters in tournament play.

The best pre-computer era CC World Championship finalists have also been analysed in the same way.
Humans can only play engine-like chess to a certain extent, regardless of whether it's Carlsen OTB last month (with his team's rigorous engine prep) or Tonu Oim spending days analysing a single move on his way to the CC Championship win in 1983.
All the best unassisted players have engine match rates for non-database moves which hover around the same % rates. They're remarkably consistent actually.
Then I analyse a player here with no real-world credentials who literally blows all the benchmarks out of the water with engine-like play, often also with many games in progress & very few draws or losses in comparison to wins.

What would be by far the most likely reason for that?

I did not realize that. I stand corrected then.

To add my 5c worth...In Purdy's book on winning the first correspondence world championship he mentions how he got into correspondence chess playing some games against a player far below him in over the board chess, and how he was quite surprised at losing...so it is possible for people to be much stronger in correspondence than OTB. Sadly for my performance on RHP, I seem to relatively stronger at blitz than at longer games...even on RHP I still make the same blunders, just at a slower rate!

No. If you will do an accurate analysis with no prejudice, I would be
interested myself, for I have no way to do it.

P.S. These matchup rates by Proper Knob covers 3 possibe moves which is
likely for anyone to match one of the 3 possible moves. I want the matchup
rate for the number one move in each case. And don't exclude the games
I lost against top players and their matchup rate in those games compared
to mine either. You don't have to mention their names.

Really? What evidence have you got to support this claim?
