I thought the solution for a problem, wasn't actually the problem? It doesn't appear so in this case. Besides, I am not sure whether to be puzzled by this puzzle...

I'm missed 2. Ne7!! (I don't have a computer program to check my problems, sorry!) Of course, I suppose this means that black does not have much of a chance in my original position, but maybe someone with a computer could check my original position....... so lets change the position to after 1....Nc3 2. Re5 or 2.h7

The puzzle is not easy . 1.Bf1 is not the right first move too.

Important in finding the solution is the first move,but the second one as well.

Yes Smiley, you are right - i gave this puzzle to a chess program and it showed at least 3 solutions - 1.Ne6 wins too.

I am sorry , this puzzle is from 1928 year -long before computers, and as Smiley showed has not one solution and is not correct.

I tried to change a little as the authors idea can work:

White to play and win

Does black have a chance? How. (by the way, to prevent confusion, the 8th rank is at the top [the black light-squared bishop is on e8])

#228 is not solved yet . I tried it but am missing something :
