DRAW

[Vinvin]

I agree this position is draw.

This would appear to be the critical line.


1... a2 2. Bd4 Rb4 3. f5+ Kf7 4. Rxd8 Rxd4 5. Ra8 Rd2

Can black draw ? The connected passers always look scary, but .....

It Looks like black can draw. Has anyone found a win for white ?

Indeed, I even tried some crazy stuff but all lines seem to draw. The a2 passer and the black kings ideal placement secures the draw.

Given the original conditions that after 1.Kg5 Rc2 (as a for instance since the rook next goes to e2), 2.Ra7 Re2 what is black's response to 3.Kf4?

But why does White take the pawn? Maybe I am trying to find a glimmer of something here that does not exist...
