And how many (including yourself) would find those moves behind the bord?
Even without improvement possible (and according to rule 4 I am not to tell it of course if there is :-))
it remains a very tricky game.
So far I have not lost with this line against 2000-2100 players and I loved the games.
And isn't that the essence of why we play? To enjoy the game?
I hate closed positions where I need to wait and wait until my opponent does make that tiny mistake, put a bit more pressure on the weak spots and , like a python, strangle my opponent in a slow death.
Besides, players with style will not like the Ziegler, will not find the line unless they are in a correspondence game and even then.
i play 2. Nc3 all the time
