{Well let's check the game from this point onwards. Is it winning for White or
a draw? Well, personally for me this is not for debate. Black king is cut off.
White king is going to slowly move up the board with his pawns. It is a
completely lost position for Black.} 42... Kf5 (42... Rb8+ $1 43. Ka3) 43. Re2

a loss as to why Sidhant didn't play this simple move. The idea is to just jog
the king down the board and pick up the a6 pawn. How can Black prevent that?}

about. A move which improves the position as a whole, but is so difficult to

the threat of h5 fixing the black pawns. But was it necessary to play it now?
I think so. And this is the reason why Niranjan is doing so well these days.
He senses these moments when he can improve his position with moves like h4.}
