The following position shows an interesting evaluation error.
[D] 4r2k/ppn1r2p/2pqn1p1/3bRp2/3P4/P1N2P1P/1PQ2BP1/2R2BK1 b - -
The setting is a fairly complex, crowded middlegame with perhaps roughly level
(that is not to say drawish) chances. The King has slightly the worse pawn
structure being hampered somewhat by an isolated d-pawn. In compensation, he has
the two bishops which if the position opens up could become very powerful.
Black's pawn formation is more compact (only two pawn islands) yet his kingside
is rather airy and he is somewhat weak on the dark squares. Most of his pawns
have moved to light squares and he is lacking his KB. A factor which could
become deadly should the position open up. I don't see an active plan for him.
If he advances his king-side pawns to attack the White castled position, the
resulting open lines and weak dark squares would probably rebound on him. In
view of this, Black should simply hold pat and play a waiting game.
Instead, Shredder uncorks 31... Bxf3?! This leads to an unbalanced material
situation with blurred positional values. The move is a pretty idea with a
forced variation that leads to this position:
[D] 4n2k/pp5p/2pq2p1/5p2/8/P1N2P1P/1PR2B2/5BK1 b - -
Black has a Q+N+6Ps vs R+2Bs+N+4Ps. The difference is Q+Ps vs R+2Bs, statically
that's 13=13. But, White's two bishops acting in concert in an open position is
certainly worth more than "6". Black's pawns are better. White's pawns are
broken up on the king-side, but are they really weak? Black has hardly anything
left to attack them with. I would think it's only a matter of time, before White
unravels his temporarily awkwardly placed pieces and gets them co-ordinated to
penetrate the Black position. This is exactly what happened in the game.
At 14 ply and over 20 minutes later, Shredder still wants to go into the line.
