The theory
The setup that saves this ending is known: knight on h3, pawn on g4.
One piece, two jobs. The knight on h3 blocks the black king's approach and stands one move from g5, where it hits the h7 pawn. A defending knight is not looking for a safe square, it is looking for a square where it does two things at once. The edge of the board is where that happens here.
The counter-break is the point. If Black pushes ...h6 to keep the knight out of g5, White replies g4-g5. That break is what makes the whole defence work, and it is why the pawn stays on g4.
Forward is losing. Nd5+, Ne6 and Ng6 all look active and all lose. So do Kh3 and Kh4. Nh3, Ne2, Ng2, Nd3 and Kf3 hold.
In this drill the rook and king press for the h-pawn breakthrough. Retreat the knight, keep the pawn on g4, and take the half point.
