Mario Richter: Thank you,Gerd! My attempt to solve this problem:
Start with 2bqkbr1/Rppppppp/5B2/p7/2P2N2/1P1KP2N/BRPPQPPP/n7

Then 49.Ne1-f3+ Re1 (best defense) 50.Rxe1+ ~ 51.Rxg1 and mate in the next move. (2010-02-27)
Olaf Jenkner: Die 50-Züge-Regel wirkt doch gar nicht, da Weiß in der Lösung ohnehin im 50-sten Zug schlagen muß. Ich hätte eine vermeintliche Nebenlösung erwartet, bei der nicht rechtzeitig geschlagen wird. (2010-02-27)
Olaf Jenkner: Im Zusammenhang mit der gespiegelten Position P0001199 ergibt die Lösung einen Sinn. (2010-05-09)
