I really didnt know where should I post this riddle, but i thought to put it in "Endgame Study"
The topic says everything.. mate in 60 (white to play)
This puzzle was devised by Dr. Karl Fabel and published in 1949 in "T.R.D. 's Diamond Jubilee" issue of Fairy Chess Review but the problem is that i really cant find a solution for this riddle.. Can someone help me??
