GM Ruslan Ponomariov (a loyal ChessPublishing.com subscriber, I might add!) was asking me if I knew of any sites where he could:
Quote:"improve my calculation of chess variations, defend difficult positions, better endgames etc."
and also where
Quote:"your results are saved on the server so that you can see your progress"
A good question! Of course, as he mentioned there are plenty of books that cover this (and there are also plenty of sites where you can do simple tactics), but does anyone know of any appropriate web sites?
I guess they would have to be very, very difficult to interest a 2700+ GM, though!
Quote:well, I also signed up on improveyourchess now, I think all the principal things seem to be covered, I didn't find anything similar on the net, the price is fair,
Good
