After looking the Fen diagram at
http://www.shredderchess.com/online-...-database.html

I understood what the position is.

It is black move
So Black moves

R-a2

In reply white has two options 1. R-b8+ Then black moves K-g7.

2. R-f1 Then again White plays K-g7.

It keeps pressure on a3 and advances other three pawns. And can win by
advancing extra pawn to Queen.

I am not great player as I easlily get beaten by Beginner Level at:

But This is what I conclude from quick analysis. Being a pawn up is a
good Advantage.
