Challenging Ending Study

I don't think the start is all that difficult to find, but it is the continuations that are hard to piece together.

From c4, the bishop guards b5 and d5, is ready to come to f7 when required, and ready to play to a6-b7 in the most relevant lines. The thing a player as white might most mistake in this sort of ending is bringing the king past the 6th rank here- it allows the black king to get too close.

I did, though I confirmed the path for black at a couple of points with the Nalimov just make sure I wasn't picking the least resistant lines. In the particular line you follow, V1, I confirmed that black lasts longer with 10.....Na8. I also confirmed later in that line a particular choice of move with the white bishop which turned out to be an only move rather than prove out all the other lines as draws myself. The basic idea isn't that difficult to get your head around- for example, in V1 after 10....Ne8, white will want to bring the bishop to a position where it can attack the knight from either f7/d7 when it is on e8, or from b7 if the knight ventures to a8. The white king will want to be placed driving the knight off of c7 from b6/d6 when appropriate. So, in V1 11.Bd5 Nc7 12.Bc4 is the right start.

Yancey, did you manage to find a win after the 10th move by yourself?

In V-1- 5.Bh1 is truly spectacular. It took me a long time the other day to find it.

It's a winning position but it requiers a lot of maneuvers to win. It's beyond my abilities so far.
