  Honza Cervenka: 6.d4 is hardly an optimal choice here and 7.Bb3 looks like a mistake (7.dxe5 is definitely a lesser evil, though I think that white can just forget on any advantage from the opening). It was black, who surfaced with advantage from the opening thanks to better development and Bishop pair and, despite of white's resourceful attempts to create tactical complications, he converted his advantage into a victory with certainty.
Jul-24-13  drunknite: I am not sure what Honza's criticism of the opening is. Rubinstein faced these first 8 moves as black 4 times in the early 20s; winning this one but draws in the other 3. It seems to be pretty popular at that time.

9 f4 seems wrong.

9 a4 would be much better, only 3 games in the chesslab database.

9 Qf3 would be very interesting and has never been played.

  perfidious: <Honza>'s view of things is most certainly predicated on what he considers the objective merits of this line for White, rather than Rubinstein's results.
Jul-24-13  drunknite: I guess Honza can explain his reasoning when he's back, in the meantime I am trying to figure out where it went wrong for white.

Is 48 Bb4 any better for white? Idea being to not allow the black K to penetrate. I played this with the crap pc at chesslab and cant seem to make progress. I get positions like this:

Again I am not good at endgames so please look this over. Usually with the black pawns so far apart it would not be hard to win the opp B ending but here the doubled pawn seems to present some problems. Not sure why the pc pushed f5. Can black not trade the g pawn and then have doubled and iso pawns on the g file?

position above is after the following:

48 Bb4 Kf7
49. Ba5 Ke7
50. Bb4+ Ke6
51. Ke3 Bd1
52. Bf8 Kf7
53. Bb4 Bc2
54. Kf4 f5
55. Ba5 Bd3

Jul-25-13  drunknite: just another thought here, the problem might be that it's the N pawn that is doubled which limits white's room to maneuver the K. if the pawn was on another file there would be room for the black K to support that pawn, then outflank the defending K, then advance the pawn. I guess....
