In this position Deep Fritz can not see the winning tactics.
[D]1R6/3q1p1Q/1p2k3/4P3/3p4/Pp4PP/2r5/4K3 b - - 0 1
Deep fritz wants to play Rc6 and it evaluate the position as 0.31 pawns for
black at depth 13 and 0.28 for black a depth 14.
Only at depth 14 it can see Qc7 and it means that it cannot see it at tournament
time control.
We need to know the evaluation of Junior6 in order to know if Junior played Qc7
because it outsearched Fritz or because of better positional understanding.
I do not know if Rb8 is the losing blunder or a previous move but my Deep Fritz
prefered 46.Qe4 with 0.00 evaluation at depthes 11-13.
The move Rb8 may be result of some learning(I did not try to play the game
manually) and I have no idea why did Deep Fritz play it.
The 0.00 seems to be a mistake in the evaluation function of Deep Fritz because
it i clear that the black pawns are more dangerous then the white pawns.
