Of course it's nice. It looks like it was published by the book's author too.
The review page does include a couple of selected pages copied from the text. I think it is pretty easy to see that the book is not aimed at beginners.
This page, for example:
It would be very nice if there were a diagram illustrating the position the author wants us to look at. Fortunately, the game is easy to find:
After playing through the game, the concept of making the opponent's piece undervalued here refers to forcing the queen and rook to defend the b7 pawn against the white rook and knight. That is pretty straightforward.
However, the win was not straightforward after that was accomplished. The position after move 28 is pretty close to the one at move 35, except that the black knight has moved from d7 to e7.
Perhaps Petrov calculated the sacrifice after move 28 and realized that it wouldn't win because the knight can stop the pawn from promoting.
So he maneuvered with his free queen trying to break through against the black kingside, seemingly without much success when the position got totally blocked up, except for the fact that the black knight ended up on e7 , where it can't stop the move 35 sacrifice on b7 from succeeding.
The technique demonstrated in the win is admirable. I think that such a technique could clearly only be appreciated by an advanced intermediate or higher rated player.

According to Chessgames, R. Grau analyzed the game in his four volume work on chess.
R. GRAU: «Tratado General de Ajedrez»
IV «Estrategia Superior»
23.Ra7 Kf7
<"Las negras se han hecho el siguiente razonamiento: mi adversario puede atacar el peón b7 sólo con dos piezas y pueden defenderlo también con dos. Por lo tanto na hay aparentemente ningún peligro. Pero se han olvidado de algo muy importante, y es que el citado peón que las blancas pueden atacar con la torre en a7 y el caballo en a5, sólo puede ser sostenido con la torre y la dama. Queda entonces al blanco libre su dama para actuar y a las negras sólo el caballo. Y como éste no podrá parar todas las entradas de la dama sin grandes debilidades, en determinado momento se hará factible el sacrificio en b7, lo que desmoronará la resistencia negra. «Debo ganar -dijo Petrovs en esta posición a un ajedrecista argentino que miraba la partida y creía que ésta debía ser tablas- porque tengo una dama muy activa contra un caballo de Grau, que tropieza con la angustia de la falta de espacio para moverse». Y este concepto magistral de la posición tuvo pronto clara evidencia.">

And Alekhine analyzed the game too:
