In the game, he gives 25.Rf3 a question mark, then analyzes two other variations. The first one, he writes 25.b3?! Rxe4 26.Rxe4 Bxf1 27.Ne6+ Kg8 28.Qb2 Ne5 29.Rxe5, then gives it the symbol, which means White has a decisive advantage. But it doesn't look like any advantage after 29...dxe5 30.Qxe5 Kf7. He then analyzes 25.Bxf1 26.Ne6+ Rxe6 27.dxe6 and says White has the upper hand. But Black looks OK after 27...d5 28.Qb2+ d4 29.exf7 Bb5.

In the game, instead of 26...Qb4, he writes that 26...Bf5 27.Nxf5+ gxf5 28.Rb3 Qc7 29.Nc3 is equal. It looks like 29...Rxe1+ 30.Qxe1 b6 should draw.

In the game, he gives 30...Bf5 a question mark. He then analyzes two moves. He writes that after 30...Re7 (which one?) 31.Nf6! is decisive. It must be 30...Rce7, since 31.Nxd6 Rxe3 32.Nxe8+ Rxe8 33.Rxe8 wins for White. But if it were 30...Ree7, then 31.Nxd6? Rxe3 32.Rxe3 Nxd6 wins for Black. Botvinnik gives 30...h5 an exclamation mark and writes 31.Nf2 Rxe3 32.Rxe3 Rc1+ 33.Kg2 Kf8 with only slight advantage for White. But it looks like White has a strong advantage after 34.Nxg4 hxg4 35.a3 and 36.Ne6.

Instead of 34...Kg6, is 34...Rd7, threatening 35...Rxd5 any better?

Instead of 38.Rd6, is 38.Rh6, threatening Rxh7+ stronger?

Botvinnik give 41.Kh3 an exclamation point, but isn't 41.Rxb7 just as good?

After 41.Kh3 Ra5, he writes that 41...Rd2 42.a4 Kc6 43.Rf7 is strong for White.

Instead of 42...b5, perhaps 42...Rxa2 43.Rxb7 Ke6 would give Black more resistance.

Instead of 46.Ra7, perhaps stronger is 46.g5, aiming for g6 and g7 to win.
