 | | MissScarlett: Offhand, I can't recall if Rubinstein ever had a world championship challenge accepted by Lasker or Capa. The problem being that it was then incumbent on the challenger to raise most, if not all of the prize fund, by soliciting monies from wealthy patrons. In that regard, Rubinstein was about as useful as a pair of sunglasses on a man with one ear. Passing around the yarmulke at the local synagogue probably wouldn't have helped much. |

| Sep-01-19 | | patzer2: It seems there are multiple solutions to today's Sunday (11. ?) puzzle. My pick was the game move 11. Nce5 with the alternative winning follow-up 12. Bxb5+ +- (+2.57 @ 35 ply, Stockfish 10). However, as <RV>'s deep Stockfish analysis indicates, even the quiet move 11. Ncd2 +- or the surprising 11. h3! +- yield a winning advantage. P.S.: So where did Black go wrong? Carl Schlecter's 1908 analysis here is correct in suggesting 10...b5? is the clear losing move, allowing 11. Nce5! +-. Instead, Black can get some practical drawing chances with 10...g6 ± to +- (+1.47 @ 33 ply, Stockfish 10), but against strong play White very likely still wins after 10...g6. So, as Schlecter's notes suggest, Black needs to look for earlier improvements. Schlecter's analysis indicates "4...Qa5+" is Black's first "bad" move. I disagree. While 4...e6
⩱ to = is arguably better, 4...Qa5+ ⩲ to = is not inherently "bad." Our Opening Explorer indictes 4...e6 is more popular than 4...Qa5+. However, the computer evaluations and results with 4...Qa5+ are about as good as with 4...e6. IMO Black's first significant problem in the opening is not 4...Qa5+ =, but instead the tempo wasting 6...Qc7? for which Schlecter has no comment. After 6...Qc7?! 7. c4 ± (+1.07 @ 31 ply, Stockfish 10), White, with superior development and more space, stands clearly better. Instead of moving the Queen a third time in the opening with 6...Qc7?, the second player can improve with 6...g6 as in Black's win in M Lushenkov vs E Najer, 2011 or 6...a5 as in the draw in S Ernst vs P Ladron de Guevara Pinto, 2019. |

| Sep-01-19 | | patzer2: <Random Visitor> Thanks for the deep Stockfish analysis of 4...e6 and a few of its alternatives. I know 4...Qa5+ ⩲ doesn't assess quite as well as 4...e6 = on computer analysis. However, I think 4...Qa5+ ⩲ is one of those moves the computers (particularly Stockfish) underestimate. Perhaps that's because it's difficult for humans to exploit any small advantage gained against 4...Qa5+. As I previously mentioned, 4...Qa5+ seems to perform about as well as 4..e6 in human play. P.S.: Wishing you well for a full recovery from foot surgery. |

| Sep-02-19 | | patzer2: <RV> Thanks again! After looking at your deep Stockfish analysis, I'm, thinking 4...e6 = is slightly better than 4...Qa5+ ⩲. In other words, it's probably better for Black to play ...e6 sooner (i.e. 4...e6 =) rather than later (i.e. 4...Qa5+ 5. Nbd2! e6 ⩲) However, I also believe your deep Stockfish analysis confirms Carl Schlecter's 1908 assessment of 4...Qa5+ as a "bad" move is at best an exaggeration and at worse simply wrong. P.S.: Of course, in 1908, Schlecter didn't have the benefit of years of practice and theory with 4...Qa5+ or a strong computer program like Stockfish to analyze it. Given those limitations and the fact that 4...e6 = assesses slightly better than 4...Qa5+ ⩲, I think he did a pretty good job of analyzing this fascinating and instructive game. |

| Aug-16-21 | | Brenin: What a player! I've just played through <Rotlewi vs Rubinstein, 1907>; the phrase "dancing across a minefield" sums it up perfectly. |
|
| Aug-16-21 | | goodevans: <Brenin> Did you mean Rotlewi vs Rubinstein, 1907 or Rotlewi vs Rubinstein, 1907? If you copy the URL into the kibitz then it will direct readers straight to the game. In fact it's possible to direct readers to a specific point in the game, e.g. Rotlewi vs Rubinstein, 1907. |
|
| Aug-16-21 | | Brenin: <goodevans>: Thanks, it's the first one. |

 | | Teyss: <goodevans: <Pawn and Pepper>?????> A pun to take with a pinch of salt. Maybe because the game is spicy and after move 15 White is a pawn ahead??
Also note the subtle alliteration in "P" which even more subtly refers to the players' names.Anyhow even if the game is a classic it's good to see it again. For info how did you make a link to a specific point in the game? |
|
| Aug-16-21 | | jith1207: <Teyss>:
As given in the example by <goodevans>, you need to add <<<<<<%20&m=22.5>>>>>>> to the URL, and 22.5 refers to the board position after move 22 from White, and position after Black's next move would be 23, and so on.It would help to do this in sharing someone the exact board position we're looking at. The other way to do the same is to include the board position diagram itself in the kibitzes. |
