Can white save this position? Can you guess the weakness in black's position that white exploits to draw this?

That part looks good, DaveCubby, but now consider the main alternative to 1......Kd6 which is 1.....Nf4.
I have got the solution for this line. If DaveCubby doesn't post the solution I will post it.
You should just post it, Alena, since there is an underlying point that I want to get to in the problem.
1.Bf2 Nf4+2.Kf3 Nd33.Be3 Rb44.Nf6 Kd65.Bd2 Rh46.Ke2 Nb27.Bc3 Rh2+8.Kf3 Rh3+9.Kg4 Rh610.Kg5 Rh211.Bxe5+ Kxe512.Ng4+It's a draw.
Alena, that is a line I never looked at, but I wonder about black's 6th move in V-2. What if black just plays 6.....Ke6? Can white avoid the exchange of the knights? Just to give you a line for exemplification, consider: 6......Ke6 7.Nh5 Nf4+ 8.Nf4 ef4 which is an easy win for black. Indeed, I can't find a way to avoid that knight exchange, and all those endings should be won black as R+P vs B endings.
In the solution I found given by the composer, he has 2.....Ng6 as black's best defense, but then I have problems with the variation he gives to the alternative of 2.....Rb3- I can't resolve whether or not 2.....Rb3 is a draw for white and maybe even leads to a cooked problem in one line, though that is judgment call, in my opinion. This is one time I would like someone with access to the Lomonosov Tablebase to offer some input into this problem- it is difficult to resolve these lines since white does always best to avoid piece exchanges, and black does best to avoid such exchanges that lose the pawn, too. In other words, I can't reduce this to positions I can be sure of, even with great effort.
Yes, Yancey you are right, my v-2 is wrong. Black will win the ending.I made a mistake on the third move.
1.Bf2 Nf4+2.Kf3 Nd33.Nxe5 Nxe5+4.Ke4 Kd65.Bg3 Rb4+6.Kf5 Rb57.Kf6 Ra5It's a draw.
I am going to have to write up a entry discussing the issues I have with this problem.
For me, this is Rambo Attack Tactic [ 1) R5e8+!! Kh7 2) Qxd2! R8xd2 3) Rexa8 ~ Black resigned 1-0 ]
