Looks almost like a engine vs. engine game to me. Virtually all moves
except the white opening choice rank among the top two choices of my
Shredder Classic.

White has difficulties around move 12 to develop his pieces. Black plans
to castle queenside which puts his rooks on the central files very fast.
Perhaps White better should look for a way to prevent this. 12. b4 Ne4
13. Kc1 looks a bit counterintuitive, but if Black now develops his
bishop on the c8-h3 diagonal White can play Ba6 preventing the queenside
castle. Also the knight is prevented from going to d3 and could be even
vulnerable on the e-file. 13...Be6 14. Ba6 (threat Bb7) 14...Rb8 15. Re1
looks quite ok for White, as does 13...Bf5 (13...Bg4 14. Bd3 followed by
Re1) 14. Ba6 0-0 15. Re1 with the threat g4 (but not 15. Bb7? Rab8 16.
Bxc6 Nf2 17. Rf1 Nd3+ 18. Kd2 Rfd8 with a very dangerous attack). If
Black concedes the tempo with 13...0-0 14. Be2 with the plan Rd1 looks
playable. Any which way White here can oppose the black rooks which is
essential.

The only mistake by Black I can see is 24...g5. Much better is 24...Rg4
protecting the g-pawn with the intention to run the f-pawn. White has
big problems to stop this pawn. For example 25. h4 f5 26. h5 f4 27. h6
g5 28. Rf7 (28. Rg7 f3 29. h7 f2! -+) 28...Rh4 29. h7 f3 30. Rxf3 Rxh7
and the black rook is behind the pawn where it belongs. Or 25. Rh3 f5
26. Rf3 f4! 27. h3 Rh4 and now attacking the g-pawn doesn't work because
of 28. Rf2 Kb6 29. Rg2 f3! 30. Rxg7 Rf4 31. Rg1 Kc5 and the passed pawn
costs the rook while White doesn't have the opportunity to munch the
queenside pawns.

Hello,

This rook ending seems advantageous for black but I find some trouble
finding a winning plan.

After 31.Rg3 Rg7 32.Kb4, ...
- if black moves his king to help black pawn, white king can eat some
pawns to obtain a passed pawn in the kingside.
- if black advances his g pawn with no help of his king, it seems white
can eat it "relatively safely".

Maybe I'm wrong and last point is not true?

I thought that Black may be able to attack the white queenside pawns=20
while the white king is away on the kingside. But the more I look into=20
it, the less this seems to be the case.

After 31. Rg3 Rg7 32. Kb4 Kb6 (Black shouldn't White allow to play Kc5=20
when the Black king is shut off) 33. Kc4 g4 34. Kd4 c5+ 35. Ke4 c4 36.=20
Kf5 cxb3 37. axb3 a5 38. Rxg4 Rxg4 39. Kxg4 Kb5 is drawn. Now I tried=20
36...Rf7+ 37. Ke4! (37. Kxg4 Rf2 38. b4 Kb5 and Black has at least=20
winning chances; 37. Ke6 Rf4 38. Ke5 Rf3 39. Rxg4 Rxc3 40. Rxc4? (40.=20
bxc4 Ra3 -/+; 40. Kd4 Rc2 41. Rg8 =3D/+) 40...Rxc4 41. bxc4 Kc5 -+)=20
37...Rf2 38. Rxg4 Rxa2 39. Kd5 (I'm not sure if White can draw 39. bxc4=20
Rd2) 39...cxb3 40. Rb4+ Ka5 41. Rxb3 and I don't think Black can win this=
=2E

Black can also choose not to advance the g-pawn to g4 and prepare the=20
attack on the queenside immediately but this gives White the control=20
over the 4th rank. 33...a5 34. Rg4 Rg8 35. Kd4 c5+ 26. Kd3! (26. Kd5 c6+ =

27. Ke5 c4 gives Black chances) and I don't see how Black can break the=20
blockade of the 4th rank.

You have gone very deep into the position, it's very difficult to find a
wining plan (if it exists)

In Batsford Chess Endings (Speelman), page 295 we can read:
"if the rook is behind the passed pawn the position is usually won"

in next page we can read:
"it's vital to keep the passed pawn as far as possible, with it only on
the 4th rank white may be able to activate his rook for one final burst
of activity" (meaning rook can eat a pawn and go to first line)

There is no menction to bad pawn structure (for the side with a pawn
plus) but I think in this case is the main theme.

There are two endings in that book about that theme, one is the well
known Alekhine-Capablanca and the second one is:

I have no more rook ending books but this one is very instructive, ...
maybe in some enciclopaedia there are a sample more close?

Don't know how close this sample position (Minus the 3-3 Pawns count on
Kingside but covering the essential) may be to you but after 44. Ra3 Ra7 I
see the scope of Defending Rook (Passively blocking the Passed Pawn) limited
only within his 4th Rank (Not in favour of generalised rules for this sort
of Rook Ending) therefore can't assist Kingside Pawns advancement and be
more involved in Kingside Counter-plays, etc.
