| Dec-12-09 | | ceebo: <johnlspouge: 23.e6 <fxe6> 24.Rxd3 Qc7 25.Rxg6+ Red8 26.Rxg7> I did a bit more digging in this line and found 23.e6 fxe6 24.Rxd3 Qc7 25.Rxg6+ Red8 26.<Qxg7> Ke8 27.Rxe6 with mate in 10 according to Rybka 2.2. That should mean that white can force mate by move 37 after playing 23.e6. |
|
| Dec-12-09 | | tivrfoa: Again I failed the continuation. 25. Rdh1 fails to Qxc3 ... But white would be slightly better. xD |
|
| Dec-12-09 | | DarthStapler: I considered the first move but I picked Rdh1 instead |
|
| Dec-12-09 | | docricardo: The move 23.e6!!! castrates the black king. Followed by 24. Rdh1 & a toxic queen sacrifice Qxg7+...and the rest is history! |
|
| Dec-12-09 | | patzer2: For today's Saturday puzzle solution, Tartakower's demolition sham sacrifice 23. e6!! decisively exploits Vidmar's weakened King position. |

Personally, minority or not, I do not regard the game variation as gospel, <ever>, so it did not bother me to find a different variation after the computer confirmed it as best play. |
|
| Dec-12-09 | | WhiteRook48: I had 23 Qh8+ immediately instead... how stupid but it actually seemed to work |
|
| Dec-12-09 | | gofer: <Once>: I like your scoring system. 0, 1/2 and 1 just doesn't seem very gratifying as I seem to get a lot of 1/2s... In passing, where is the commitment from the Brits to post first?!?! Its only 5am our time, surely someone in the UK works awful hours or better still is out partying until 5 am and then wants to solve MOTD! :-) |
|
| Dec-12-09 | | muralman: Yay, first win of the week! |
|
| Dec-12-09 | | Quentinc: <AxelBoldt: White can play 23.Rh1 e6 24.Bxg6 which looks pretty good>
Thanks, that does look good. |
|
| Dec-12-09 | | shishio71: Okay, now I see why 23. Qh8+ doesn't work:
23. Qh8+? Bxh8 24. Rxh8+ Kg7 25. Rdh1 Rxh8 
e6 is a nice little move, though |
|
| Dec-12-09 | | TheBish: Tartakower vs Vidmar, 1905 White to play (23.?) "Very Difficult"
About my only candidate move was 23. e6, except I did consider 23. Rdh1 with the threat of mate in 3 starting with 24. Qh6+, but Black simply plays 23...e6! and White just loses a piece now after 24. cxd3 b4. 23. e6!
This boxes in the king and threatens 24. Bd4 and a quick mate. Much better than 23. Rxd3 Qd7! where White is better, but not crushing as after the text. Black is pretty helpless here, can only delay mate a few moves. A) 23...fxe6 24. Rxd3 Qc7 (or 24...Bxh6 25. gxh6 followed by Qg7#) 25. Rxg6 Red8 26. Rxg7 Ke8 27. Bb6! Qb7 28. Ne4! where Black can only delay mate by giving up heavy wood starting with 27...Rxc2+. B) 23...Rxc3 24. bxc3 Bf5 (24...fxe6 is similar to A) 25. Bd4 f6 26. Rxg6! Nb3+ (spite) 27. cxb3 Bxg6 28. Qxg6 Kg8 29. Rh1 and mate next. C) 23...Bf5 24. Bd4 f6 25. Rxg6! is the same as B without the preliminary exchange sac. That just about covers it... on to the game! |
|
| Dec-12-09 | | Formula7: Hmm, 23.Rdh1 threatens 24.Qh8+ Bxh8 25.Rxh8+ Kg7 26.R1h7#, but 23...e6 foils that plan. However, White can prevent e6 by playing e6 himself, leading to the following variations: A) 23...fxe6 24.Rxd3 and White takes on g6 on the next move with a mating attack. B) 23...Bg7 any 24.Qxf7#
C) 23...Rxc3 24.bxc3
D) 23...anything else 24.Rdh1 and the threat of 25.Qh8+ Bxh8 26.Rxh8+ Kg7 27.R1h7# cannot be stopped |
|
| Dec-12-09 | | lost in space: Well, no time today to solve the puzzle.
But after 23.e6 Rxc3 it seems that
24. Rdh1! Rxc2+ Kd1
click for larger viewis much better than the text (24. bxc3). Mate to follow |
|
| Dec-12-09 | | butilikefur: what? why not 25. Rh1 ... |
|
| Dec-12-09 | | butilikefur: 25. Rh1 Qxc3 26. Qh8+ Bxh8 27. Rxh8+ Qxh8 28. Rxh8+ Kg7 29. Bd4+ f6 30. gxf6+ exf6 31. Rxd8 Bf5 32. Re7+ Kf8 33. Rf7+ Ke8 34. Bxf6 and White is won (34...Nc6 35. Rc7) but 25. Bd4 is far stronger |
|
| Dec-12-09 | | BOSTER: I don't think that one hundred years ago the Sicilian theory was the same, what we have now.
But I guess it was much better to play 17...e5 to open the window for his king , and even in the such position black could continue the fighting. |
|
| Dec-12-09 | | butilikefur: hey what about 19. Nf5 gxf5 20. Qh7+ Kf8 21. exf5 with the idea of getting in g6 and Bh6 |
|
| Dec-12-09 | | ccolby: Help me here. I have black back at move 14. I've neglected the advance of white pawns, and now I have a critical choice. I think hxg6 leaves me indefensibly open along the h file. What's more, this choice comes up a lot. Why not play fxg6? |
|
Dec-12-09
 | | OhioChessFan: <ccolby> 14...fxg6 is probably a little better. I think part of it is simply the way chess was played in 1905. Anyway, if 14..fxg6, 15. 0-0-0 and White still looks good. |

| Dec-13-09 | | David2009: Saturday's puzzle Tartakower vs Vidmar, 1905 White 23? 23 e6 Ng3+ 24 Kb1 Rxc3 25 bxc3 Qa5 26 Rh1 Bxc2+ 27 Kxc2 Qxa2+ 28 and IF White can
escape the perpetual check, White mates first. 23 Rh1 first doesn't work: e6! and the black K escapes
via e7. This is far as I have time for (we are away from home, guests). If Black does not play Ng3+,
White mates on the h file with 24 Rh1 etc. I don't have to decide the best reply to Ng3+ immediately:
perhaps 24 axb3 allowing Qa5 is safe or even 24 cxb3 Rxc3+ 25 bxa3 Qa5 26 Rxd3! and White wins on material.
On reflection I like this last line better than Kb1- it is a humorous twist (White, denied his Q sacrifice, decides to win on material instead). Time to
check:
=====
Black plays 23...Rxc3 immediately and then counter-attacks with his
Q on c8. I wasn't too worried about 23...Rxc3 and to save posting time didn't analyse it. Tine to digest the other comments. |

You are white, drag and drop the move you want to make. |

| Apr-03-11 | | adbat: White does not get the equalizer. On move 39, but Kd3 Kb2 not play with this line, 39.Kd3-Qa1 / 40.Re7  Ke8 / 41.Rb7-Qa2 + / 42.Kd3-Qe6 / 43. Ke7 fe7 and White wins, or 40 ... Kg8 / 41. Kg7 Kh8 / 42. Kb7-Qa2 + / 43. Kd3-Qd5 / 44.f7 + and White wins. |
|
| Jan-01-17 | | dfcx: White is down a piece. But with
23.e6!
black king's escape route is blocked and all black pieces are too far to defend the H file.If black plays 23...fxe6 24.Rxd3 Bxh6 25.gxh6 and mates next. And 23...Bxh6?? 24.Qxf7#
All other moves can't defend against the threat of Rh1. Is this a New Year's gift from CG? |

| Jul-28-19 | | Scuvy: Tartakower, in his best games collection, says Maroczy was watching this game as it was being played and remarked at its conclusion "The East threatens us." |
