Stockfish gives Rf2 score of +2.1 and does not need Na8!! Who needs Na8 when you can play Rf2, huh?

Out of curiosity I tried to run Stockfish with multiPV=20 (deeply analyze all moves). Na8 had -2.2 score most of the time. At depth 19 Ra8 got score of -0.5 but at depth 20 it fell to -2.2.

I thought that a lone king can not hold 3 pawns at once, I was wrong. :)

Everyone needs Na8, if Na8 is much better than Rf2...

Great position, if it is correct.
My little analysis:
1.Na8 Nxc2
2.Kxc2 f5
3.dxc4 a4
The move 3. ...a4 is not in your analysis.
Now stockfish gives a score of zero at depth 32.

Do you have an idea how to win after 3. ...a4 ?
Kind regards
your patzer Bernhard

Of course:
1.Na8 Nxc2
2.Kxc2 f5
3.dxc4 a4
4.a3 Game over 1:0
White wins against 3 Pawns
