Can white save this position? Can you guess the weakness in black's position that white exploits to draw this?
1r6/2k5/8/3np3/6N1/4B3/6K1/8 w - - 0 1
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.
