One thing I might have noticed, is that F9 seems to 'understand' dutch middlegames a bit better than F8, consistently evaluating the positions in the game I looked at half a pawn less, i.e. e.g. 0,28 instead of 0,78 despite being able to gain the bishop pair with Ne6 Bxe6 dxe6. 

Though so far I've only gone thru one game, so it might be an exception...

Bonsai,

test 1:



test1 gave the following result:

Fritz 9: 1) 1.Kd1 d4 2.Rf7 c4 3.Rd7 d3 4.Rg7 d2 5.Re7 -1.20/18 
Fritz 9: 2) 1.Rf7 d4 2.Kd1 c4 3.Rd7 d3 4.Rg7 d2 5.Re7 -1.20/18 ; 
Fritz 9: 3) 1.Rc7 c4 2.Kd1 d4 3.Rd7 d3 4.Rg7 d2 5.Re7 -1.20/18 ; 
Fritz 9: 4) 1.Ke1 d4 2.Kd1 c4 3.Rd7 d3 4.Rg7 d2 5.Re7 -1.20/18 ; 
Fritz 9: 5) 1.Rg7 d4 2.Kd1 c4 3.Rd7 d3 4.Rg7 d2 5.Re7 -1.20/18   



test2

Fritz 9: 1.exd4 Qd6 2.d5 exd5 3.Qe5 Nc4 4.Qxd6 Nxd6 5.Nxd5 Ng6 6.Ne7+ Nxe7 7.Rxd6 a5 8.Rb6 0.20/15  Line

Fritz 9: 1.Rxd4 Nec6 2.Rd3 Nb4 3.Rd1 Nc4 4.h4 Rc8 5.h5 h6 6.Bf3 Kh8 7.a3 0.02/15  Line



And finally test3, a classic. I suppose most humans would find the first few moves of the drawing idea in no time and then figure out how to deal with the ...Qa6 infiltration after a little thought.

Both fritzes are clueless so far, and I don't have the time to wait until ply 30 is reached - if that would help...:

I'd be interested to know whether F9 sees the draw for white (to move) in this position. This seems to be beyond Fritz8 and Shredder7 (they occasionally have the right move as their best move, but then swap it for something else again and never evaluate it correctly - all programs seem to believe that white is lost here):

This is a position where Fritz8 finds the best move exd4!, but I wonder whether a too positional program might not find it:
