Subject: Forth example. A bit more complicated. But still Shredder losing!

Author: Rolf Tueschen

Date: 10:57:39 09/15/02


I'm now researching Rebel Macheide's wins with White. The forth example is also
about a terrible weakness of Shredder, only a few moves after leavin books this
time.

Here is the game with a few annotations from my side. Better chessplayers might
give in depth commentaries.

the secret of that position? All these questions are not discussed.
