Hello ,
when i saw your post , i try Fritz 5.32 , to check the possible Blunder ...
Fritz doesn't think during analysis , that Ne4 is a blunder ...
During 15 secondes he analyses
20.h4 Qe3 21.Qd4 Qxd4 22.Rxd4 Rad8 23.Rxd8 (-0.03) as the best move ...
Then he split to
20.Ne4 Qf4 21.Nd6 Rhd8 as the best move (and line ) for white....
After 40-45 secondes this line is discarded with the following moves ...
20.Ne4 Qf4 21.Nd6 Rhc8 22.Nxc8 Rxc8 (0.00)
and he prefers then to play 20.h4 ....but for fritz there is no blunder at all !
i will continue the analysis with Fritz 8 , Junior 8 and the King 3.23....
i will analyse this evening ...
regards
Nicolas
It probably needs a little more time. After forcing Ne4 the Baron gets fail highs on Qf4. But it takes quite a while on my P3-500 (8.5 minutes)
On the position _before_ Ne4 the Baron says white is a little better (+0.37)after 43 minutes of thinking (on 20.h4).
Richard.
so this means that theposition is not so easy to analyse for an engine... fritz nedds several minutes to advocate 20.h4....
The position is certainly not easy. But the Baron never considered Ne4 and went for either Rd1 or h4 from the start.
I'm currently checking the position after 20.Qf4 as Uri said that Re1 might save the position. Currently, after 32 minutes the Baron says that the position after Re1 is probably a little better for black, but not by much.
