11...d4! <Hoffer calls it a valuable innovation>

18....b6! 19.h3?!

The game is already lost for white and 26.Rd4 is not the decisive error. Other tries like 26.Rd3 are no better (e.g. black goes for f6 to threaten Bg6 and Ra4-a3 to attack the a-pawn etc.)

11...d4! The disaster is moving ahead! ;0)

12.exd4?! [Black supports the disaster, so to speak! Better was 12.♘xd4 ♖d8 13.♕b3 ♘xd4 14.exd4 ♕xb3 15.axb3 ♗e6!? 16.♗f3 ♖xd4 17.♗xb7 ♖b8 18.♗f3=]

12...♖d8 13.d5? [A terrible move! More interesting would be 13...♗c4!? to keep an eye on d5 and f7 or 13...0-0]

13...♘b4! 14.♗f3 ♘bxd5 [14...♘exd5!? 15.♘xd5 ♘xd5 16.♗xd5 with the idea of 16...♗e6! 17.0-0 ♗xd5 18.♕e2 h6!? 19.♖fd1 and 19...♗xb3!]

15.♗xd5?! [Inaccurate! It would be better to exchange (or at least to try to start one, but who wants to reach the endgame against Rubinstein ;0) ) the queens with 15.♕d4!? and a possible continuation would be 15...♕e6!? 16.♕e4 ♘xc3!? 17.bxc3 ♖b8 18.0-0! ♕xe4 19.♗xe4 ♗e6=} but in this position I would prefer to play with the black pieces.]

15...♗e6 [15...♘xd5!? 16.♘xd5 ♕e6+! 17.♕e2 ♖xd5 18.♕xe6 ♗xe6 is also possible]

19...♕xd4 20.♘xd4 ♗d7 21.♘c3! ♘xc3 22.bxc3 ♖dc8 23.♖ac1 ♖c4 24.♖fd1 ♖ac8 25.♘f3? doesn't work because of [25.♖d3 looks ugly. Better was maybe 25.♔h2 or 25.f3]

25...♗e8! 26.♖d4? [Finally black must bite the bullet and accept it's weaknesses with 26.♖d3]

26...♖xc3 27.♖xc3 ♖xc3 28.♖d8 ♔f8! 29.♘d4? We've made it, but unfortunately a bit toooooo late! ;0) [Better was 29.♖d2!]

29...♔e7 [Better was 29...♖c1+! 30.♔h2 ♖a1]

30.♖a8 ♖a3! [30...♖c7 would be too passive]

31.♘f5+! is a wise decision! ;0)

31...♔f6! 32.g4? and the rest was pure routine! [32.♖xe8! ♔xf5 33.♖e7 ♔f6 34.♖e2!]

32...♗d7! 33.♘g3 ♖xa2 34.♖h8 [34.♔f1 or 34.♖b8]

34...b5! 35.♘h5+ ♔e7 36.♖xh7?(?) b4! 37.♖h8 He's late as usual! ;0)

37...b3 38.♖b8 b2 39.♔h2 ♗a4 [It would go faster with 39...♔d6! 40.♔g3 ♔c5! 41.♖xb2]

40.♘f4! White makes his best move(s) in a completely lost position! ;0)
