Shredder12 schafft es auch auf alter hardware ganz fix.
Nach weniger als einer Minute hat er 1.c3 Kb3 2.Ta1 usw.
anfangs mit 0.00 später mit > 6 BE.

Hallo Anton!
Schöner ist aber dieses Abspiel mit dem stillen Schluss:
1. c3+ Kb3 2. Ra1 Ra4 3. Rxa4 Kxa4 4. Kb1 c5 5. Ka2 c4 6. Ne3 Qxg6 7. Nxc4 dxc4 8. Bxc4 Qc2 9. g3 gewinnt. Oder?
