Quote: In second place, if dxc4 is good for Shirov, who have used it regularly, it could be good for anyone
Every chess coach is telling one should play opening lines that fit to the own personal style. So what is good for Shirov might be very bad for somebody else.
Shirov is an intuitiv (or at least more intuitive than most of the top GMs) attacking player, my style is more or less the opposite of that.
The line 7...dxc4 8.Bxc4 e5 is a razor sharp variation, black has -no doubt- more solid possibilities against the shabalov. Shirov likes such variations, me not.
How to estimate this line objektivly is of course another question. From my experience in corr and freestyle chess I am quite sure that white's advantage is more than just academical. Ok, in OTB chess this might be not so relevant since the positions are very complex and the stronger player (in these kind of positions) will win.
Quote:And in third place, it is abolsutely NORMAL for White to tretain a small advantage in most openings,
I must completely disagree with that statement. Most opening variations lead to complete equality (one of the exceptions might be some variations in the Najdorf where the position just stays dynamic and does not simplyfy, so unclear instaed of equal) if blacks chooses the best (or one of the best) variations. Of course I do not say that its always easy to find out (even not at home with the help of databases and engines) which is the best line for black for equality.
So my question is: Which is the best line (for equality ! ) against the shabalov ? Of course we can start debating now
7...Nxg4 8.Rg1 f5 is very solid, but it could be slightly better for white. 7...h6 is maybe the best move. I am not 100% sure, but so far I did not find any advantage for white.
