The winners met in the fifth round with GM Bischoff playing White in a game that started with SP888 RBQKBRNN. After a few fairly routine moves, White played 5.d3, reaching the position shown in the top diagram; the start position is still discernible. Black replied 5...Nf7, when White pushed the d-Pawn once more, 6.d4.
Why not play the Pawn to d4 on the fifth move? I'm really not sure. Perhaps White was concerned about 5...Bf7, when the square c4 is available to the Bishop. After ...Nf7, the Bishop move is no longer an option. Whatever the reason, after 6.d4, the game took a tactical turn with 6...d6 7.c4 e5 8.Bc3 e4 9.d5 Ng4 10.Nd4 Bd7 11.h3 Ngh6, reaching the position shown in the bottom diagram.
The next few moves saw both players castle to the same side: 12.O-O c5 13.Nde2 O-O. Now White owned the long a1-h8 diagonal, where he built a Queen / Bishop battery. Black had no effective counterplay and was lost after 30 moves. To play through the complete game, here is the PGN as provided by schachclub-waldbronn.de.

That must set some kind of a record for most tags in a single PGN game score.
