This instructional game has a steady stream of basic fundamentals that advanced students should understand. Start w/the transposition from C-K to NID (universal Panov attack), why the Black knight does not capture the IQP initially (but does so later in the game), Horwitz Bishops, why the White queen adjusts her positions (defense, battery, pin, etc.), the exchange sacrifice, outnumbering, and hole on 6th mate threat.

Note that 25...Qd2, 26...Rac8 threatening back rank mate delays White's finish. Chess often pressures a particular square and it's defender. Additional resources must be found.

Caro-Kann "Exchange variation and Panov-Botvinnik Attack

The Exchange Variation is 1.e4 c6 2.d4 d5 3.exd5 cxd5 (4.Bd3). The Panov-Botvinnik Attack begins with the move 4.c4.

This (Panov) system often leads to typical isolated queen's pawn (IQP) positions, with White gaining rapid development, a grip on e5, and kingside attacking chances to make up for the long-term structural weakness of the isolated d4 pawn. The major variation in this line 4...Nf6 5.Nc3 e6 6.Nf3, when Black's main alternatives are 6...Bb4 (a position which often transposes into lines of the Nimzo-Indian defence) and 6...Be7, once the most common line. 6...Nc6?! is inferior as it is favourably met by 7.c5!, after which White plans on seizing the e5-square through the advance of his b-pawn to b5 or by exchanging the Black's Knight on c6 after Bb5.

The "true" Exchange Variation begins with 4.Bd3 Nc6 5.c3 Nf6 6.Bf4 Bg4 7.Qb3 This line is thought to have equal chances for both sides, and was tried by Bobby Fischer. Some of the strategic ideas are analogous to the Queen's Gambit declined, Exchange variation, (1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.cxd5 exd5) with colours reversed."

Fredthebear says the Panov Attack often produces kingside attacks in 30 moves or less like the game above. The queenside pawn structure might not factor in that much. That being said, the next link is a more detailed explanation of the pawn structure, with a comment on transpositions toward the bottom of the article: https://simplifychess.com/pawn-stru...

Note that the Panov Attack is far more common from a Caro-Kann Defense (B13-B14) than from a queen pawn/Indian defense. There is no Panov Attack if the e/c pawn exchanges don't fall a certain way to generate an isolated queen pawn (IQP/Isolani). White can dictate such (3.exd5) against the Caro-Kann Defense. However, White often plays e3 in the queen pawn games, and must await for ...cxd4, exd4 to generate an isolated queen pawn.
