Nov-26-07  Karpova: This game is from the International tournament in Prague (round 8) and won the second brilliancy prize.
Nov-28-08  Ulhumbrus: After 16...f5 it is not obvious that it is easier for White to start an attack on the King side by playing g4 than it is easy for Black to start a King side attack by playing ....g5. The reason for this is that the e4 pawn blocks the long diagonal for Black's QB whereas White's QB can be uncovered on the long diagonal by d5. This makes the move ...g5 more dangerous for Black than the move g4 is dangerous for White. Janowski does manage to arrange the pawn advance 25 g4 whereas Rubinstein does not manage to arrange the advance ...g5, and Janowski goes on from there to win.
May-22-19  zydeco: A key point is that 34....Bxd4 loses to 35.Bxd4 Qxd4 36.Be6+! Kh8 37.Rf8+

  tamar: Rubinstein has the idea of e5, but plays it on move 32 when White's initiative on the K side is too great.

27...e5 is sharp, but seems to work.

28 dxe5 is no good after 28...Rxd1+ 29 Bxd1 Qd8 when White is helpless against Qd1 so that leaves

28 fxe5 f4 29 Bc1 h6 30 Kh2 Bg5 31 d5 f3 32 Bxf3 Bxc1 33 Rxc1 Qf4+ 34 Qg3 Qxc1 35 Bxe4

Black has an extra rook, but the pawns look dangerous.

SF finds the best win here with 35...b5! 36 axb5 a4 37 bxa4 Qxc4 an echo of the original breakthrough .

Jun-12-21  sudoplatov: The final combination is a bit reminiscent of Janowski's game against Alekhine at Mannheim 1914.

One amusing thing in this game is that by move 16, both Janowski and Rubinstein got their Two Bishops.

Aug-26-21  Brenin: 42 d5 Rf7 (obvious, although 42 ... Rg2 43 Bxf6 Qxf6 44 Rxf6 Rxg4+ gives Black a slim chance of survival) 43 Rxf6 Rxf6 45 Qe6! Qxe6 (forced) 44 dxe6 Kg7 45 e7 Kf7 46 Bxf6 wins.
Aug-26-21  Cheapo by the Dozen: I didn't see 44 Qe6 in advance. I thought a quieter 44 Qh4 would lead to a winning endgame, for various reasons of pawn structure, but the engine disagrees. My error was to rely on the line

44 Qh4 Kg7
45 Kg3

to easily get rid of the e-pawn -- but actually Kg3 is impossible due to the Black queen.

  drollere: i had 42. c5 bxc5, 43. dxc5 Qe6, 44. Bxf6+
Qxf6, 45. Rxf6 . the pawn shove forces black to either give up the Q or give up a tempo. if 42. .. Qe6, 43. Qxe6 Rxe6, 44. d5
Aug-26-21  Tiggler: I got the first two moves, but missed the brilliant 44 Qe6! Instead, I chose Qf5. That results in exchanges of all the pieces and a clearly won K+pawns endgame for white.
Aug-26-21  mel gibson: It took me a minute to find the solution
then it looked easy.

  OhioChessFan: Beautiful combination. Figuring out exactly when d5 was needed was the key.
Aug-26-21  Knightmare07: it took me a while but after finding d5 the rest was simple
Aug-26-21  Granny O Doul: I also didn't think past 42. c5. I guess after ...Qd5 43. Rxf6 Rg8 it's still a little wriggly.

  agb2002:

White is one pawn down.

Black threatens Rg7.

White can achieve a won ending with 42.d5:

A) 42... Rg7 43.Bxf6 Qxf6 44.Rxf6 Rxg4+ 45.Kf2

A.1) 45... Rg6 46.Rxg6 hxg6 47.d6 wins.

A.2) 45... e3+ 45.Kxe3 Rg3+ 46.Ke4 Rxb3 47.d6 Rb1 (47... Kg7 48.d7) 48.d7 Rd1 (48... Re1+ 49.Kd5 Rd1+ 50.Kc6 Kg7 51.Rd6 wins) 49.Rf8+ Kg7 50.d8=Q wins.

A.3) 45... Kg7 46.Rxb6 and the remaining black pawns are vulnerable with the white king in front of those passed but the black king is far from White's passed pawns.

B) 42... Rf7 43.Rxf6 Rxf6 44.Qe6 Qxe6 45.dxe6 Kg7 46.e7 Kf7 47.Bxf6 wins.

C) 42... Bxc3 43.Rf8#.

  Teyss: Couldn't find a clear "puzzle win" after 42...Rg7 43.Bxf6 Qxf6 44.Rxf6 Rxg4+ although the position is indeed winning so gave up. Bah, wouldn't have figured out the other line 42...Rf7 until the end anyhow.

Lesson for me: first check the shortest line (42...Rf7) and if it's winning, make an effort on the longest one (42...Rg7), you lazy idiot.

Beautiful combination.

Aug-26-21  awfulhangover: Lovely technique. I wish I could play like this.
Aug-26-21  TheaN: Bit of a sour aftermath if you see what White had to calculate beforehand: <42.d5 Rg7 43.Bxf6 Qxf6 44.Rxf6 Rxg4+ +-> left me a bit in the dark as to whether this was the way to go. It's obvious that the perpetual pin after 42....Rf7 doesn't work for Black, but he might have seen the above line and decided it was lost.

In the main line I played 45.Kh3?! ± hastily to win a tempo on the rook, it's probably still winning but not as definite after 45....Kg7 46.Rxb6 Rg6 ± as e3 becomes annoying. OTB I'd taken another minute to analyze the end game, then 45.Kf2 +- is obvious.

Aug-26-21  Autoreparaturwerkbau: Opening the diagonal with 42.d5

is the key to white's advantage in ending, but it is far from straight-forward as after more-or-less <FORCED line> 42...♖g7 43.♗xf6 ♕xf6 44.♖xf6 ♖xg4+ 45.♔f2 h5 we get to


click for larger view

that needs very precise play to overcome black's advanced e+h pawns threat whilst keeping upper hand with c+d pawn promotion combo.

All-in-all, 42...♖g7 certainly puts white much more on tip of toes as 'resignatory' 42...♖f7, that was actually played.

Aug-26-21  Cellist: I wanted to play Qe6 directly after 42. ... Rf7. It also works: +10.45 (26 ply) 43...Rg7+ 44.Kh1 Qxe6 45.dxe6 Bxc3 46.Rf8+ Rg8 47.e7 Bb4 48.Rxg8+ Kxg8 49.e8=Q+

Aug-26-21  TheaN: <sudoplatov: One amusing thing in this game is that by move 16, both Janowski and Rubinstein got their Two Bishops.>

Surprisingly, this is rather common in a Rubinstein/Zukertort setup; White's idea is to try center breaks with the knights, and for Black to keep some game will more often than be trading them off. This often shows in the Ne5/Ne4 transactions.

Bishops only really face off with each other or Knights in Bg5 or Bb4 situations, which are uncommon because of Bb2 and c5. The only exception is Bd6 eyeing on Ne5, but Bxe5 is almost always a death sentence as White then has a free game on the king side.

The system is surprisingly interesting from White's point of view, I have it in my repertoire as a 'surprise/uncommon' option, I bought Rudel's book a couple of years ago; it's definitely defendable and can be enjoyable for Black if you counter sufficiently, but can be very suffocating if you don't.

Aug-26-21  Stanco: I did solve d5 variation which leads into rook vs rook endgame where white captures b6 pawn and wins. I also believed the position is hiding a better move but failed to find it.
