In The Immortal Games of Capablanca, Reinfeld gives exclamation ks to
both 25.a4 and 26.b3.
I can understand 25.a4, although it is not clear to me that this is the best
idea in the position. However, 26.b3 looks like too much of a good thing,
when 26...b4 might have caused White some problems. I think Black's
advanced pawns will prove a weakness in the long run, but maybe not fatally
so, and in the short run it looks like Black could have got some badly
needed counterplay. For examape, 27.Ne2 (I can't see that 27.a5 leads to a
clear advantage) 27...cxb3 and now White almost has to play 28.Nxb3. Then
Black is probably compelled to play ...e5 at some point, and he may even
have to give up a pawn, but it looks like he can generate some play against
White's queenside.
I'm wondering if this sort of pawn advance by white either to undermine or
to lure black's pawns forward is the standard recommended procedure in this
type of position, or if this is a case of White simply making some
provocative moves and eventually winning because he was simply a better
player rather than winning an objectively winning position on technique.

Well, the basic idea in this position is to dominate the Bc8 with the
Nc5. White doesn't necessarily want to open files on the queenside but
seeks to fortify the Nc5 and also likes to fix the black pawns on white
squares. a5 (by White) followed by b4, doubling the rooks on the d-file,
Rd6, capture the a-pawn and queen the a-pawn sounds like a plan. A plan
like 27. axb5 axb5 28. bxc4 Rc6! 29. Nd7 bxc4 30. Ne5 wouldn't be good
because the knight is pushed away from its dominating position. Then the
Bc8 could develop to b7 where it exerts pressure on the long diagonal.
Immediately 26. b4 would be countered by bxa4 and the b-pawn is attacked.
Black decides to get rid of his weak queenside pawns as much as
possible, but he could also try to put them on black squares and kick
the knights around. If Black had played 26...b4 Capablanca for sure
wouldn't have retreated the knight to e2 as this would be followed up by
Rc6 and the Nc5 also has to go. Instead he would have played 27. a5 Rc6
28. N3a4 maintaining the position of the Nc5. This position is much
worse for Black as it might look. Whether Black opens the c-file or not
(White has the little threat of 29. c3 bxc3 30. b4 and moving up on
those pawns with the king), White will double the rooks on the d-file
and intrude along this file into the black position (target d6 or d8).
Then the black pawn at a6 will become very weak.

I think more precise and up to the point was 29. b4 as now Black has the
opportunity to move the a-pawn away from a6. This frees the rook from
defense of the pawn and makes a6 available to the bishop.
> Nf6
Better immediately a5 as White could again obstruct it with b4.
> 30.Rd2 a5 31.Rhd1
Obviously Capablanca follows another plan: to exploit the d-file. But
with the pawn at a5 Black has better chances to equalize.
> 31...Nd5
Black closes the file as White would have followed up with Rd6.
> 32.g3 Rf7
I think Yates loses the plot here. He wasn't very far from equality if
he tried to control e5. This restricts the white knights. Black could
then try to activate his bishop via a6. For example 32...Kf7 33. Nd3 Kf6
34. Nac5 Rd8 35. e4 Ne7 36. f4 Rd4 37. e5+ Kf7 followed by Nd5 and Ba6
(28. Kc3? Rxd3+!).
> 33.Nd3 Rb7 34.Ne5 Rcc7 35.Rd4 Kg7
> 36.e4 fxe4
After this it's difficult to defend. Probably better was 36...Nf6 37.
Nc3 (if 37. exf5 exf5 the black pieces have e6 and e4 available. White
has nothing here.) 37...Nd7 38. Nxd7 Bxd7. Black plans to double the
rooks on the c-file (c5 and c7) and has counter play.
37.Rxe4 Rb5
Making the task easier. After 37...Kf6 38. f4 Kf5 39. Rc4 is not
possible because of Ne3. If 39. Rdd4 (plan Rc4) 39...Rb4 40. Rxb4 axb4
41. Rd4 (threat g4+) 41...h5 42. Rc4 (else Ba6) 42...Ba6 43. Rxc7 Nxc7
and the game isn't over yet. White has to be careful that Black doesn't
intrude on g4, so he can't attack b4 so easily.
> 38.Rc4 Rxc4 39.Nxc4 Bd7
Black can prevent the knight manouvre only by Nf6, but this opens the
d-file for the white rook. Either the a or the e pawn will fall.
> 40.Nc3 Rc5 41.Ne4 Rb5 42.Ned6
> Rc5 43.Nb7 Rc7 44.Nbxa5
Finally the pawn is gone. The rest is essentially pushing the pawn to
queen. In despair Yates tries a counter on the king side, but Capablanca
keeps everything under control.

Thank you for your thoughtful response -- you bring up several ideas I had
not considered.
Best regards,
