Can't see your diagram. It just says "loading". This is the case on 3 different browsers, and happens fairly often. Anyone else get that? Maybe give the diagram in forsyth as well?
Only promotion to B wins, part 2
Sort:
8/1P6/8/8/p1p5/k1P5/p7/K7 w - - 0 1
Wow that's amazing. I didn't think such a simple position could exist. Maybe it's possible to retrace some previous moves and make it the climax of some study?

I can't see the diagram either. Did you set up the position while on V2 of the site or something? Anyway, here's the position.
8/pP6/k7/8/K7/8/6p1/6N1 w - - 0 1
Messing around, I found this, which only has 6 units. It seems to be exceptional - most locations of the wN/bP pair allow for White to win with b8=N as well. However, the diagram here breaks the general "Troitsky line" rule, discussed recently in another topic.

Yes, I used v2. v3 is almost impossible to do on an Android phone.
Speaking as a programmer, v3 is poorly written code in general.
It isn't a brilliant study or anything, but how about this?

The exchange for White is obvious; if the heavy pieces come off, the b-pawn is in the clear.
Black can try 1...fxe5 but that looks lost also.
The solution is longer, but not much (or any) more difficult.
I came up with a better composition than in the last thread of similar name.
White to move and win
