|Jan-20-12|| ||Once: I think some of CG's ground rules have slipped a little over the years. It's not unknown to have multiple good solutions. We had one of those just the other day.|
And CG will sometimes give us positions where the best move isn't the one that was played - for instance when the player missed the best continuation.
So I think that (b) and (c) from the list that <phony> quotes are "usually" rather than "always".
Perhaps it would be a good time for CG.com to update this and put it in their FAQ?
|Jan-20-12|| ||JG27Pyth: Felt good when I finally saw the Queen sac to put the ribbon and the bow on the finish. Lovely combination -- new to me but it seems like it ought to be a classic.|
|Jan-20-12|| ||Phony Benoni: <FSR> Interesting that this game would appear in Foldeak's book on the Olympiads, since it wasn't played in one. It's certainly beenpublished enough other places, though. My introduction was Coles' <Epic Battles of the Chessboard>.|
|Jan-20-12|| ||FSR: <Phony Benoni> D'oh! You're right, I saw it someplace before, but not there.|
|Jan-20-12|| ||doubledrooks: I went with 34. Re8+ Bf8 35. Rxf8+ Kxf8 36. Nf5+ Kg8 37. Qf8+ Kxf8 38. Rd8#|
|Jan-20-12|| ||poachedeggs: It is not "difficult" because continued check is the only option...
Then it boils down to seeing that a Q+ on 38 is the only viable move rather than a R+ on 38...|
The only other thought is where the N needed to go on 36...but the discovered + to f5 seems natural & looks very dangerous...and eliminating the flight square g7...so that probably lit the light bulb of the Q sac.
|Jan-20-12|| ||zakkzheng: I was really amazed when
I saw the move Qf8+,I am prety sure I saw this example before,oh pooy me.
|Jan-20-12|| ||sfm: Ah, this one, always loved it. What fireworks!|
|Jan-20-12|| ||sfm: If Euwe played 31.Nxd6!! but didn't consider what follows, until 33.-,Qf4, he is one sloppy fellow. Then on the other hand, if he saw all the way through to 37.Qf8+, he is one amazing genius. I believe in the latter.|
|Jan-20-12|| ||Once: Ah, um, Euwe was playing black. He lost. So I ... er ... guess he didn't see all the way through to 37. Qf8|
|Jan-20-12|| ||The Rocket: got it! very nice! but not difficult level to me|
|Jan-20-12|| ||Gilmoy: I am tickled to rediscover this game again; I remember the combo, but long since forgot the players.|
The one charming tidbit of analysis I recall (IIRC, by one of the US authors: IC, FR or so) was <how early> Vidmar had already decided on "repeated sacs on f8": some mind-numbingly remote position like <24..Rac8>. It's not even possible yet; but he's already spotted it as a fantasy line. The rest of the midgame amounts to a rilly deep "swindle" (although White wasn't necessarily already-lost when he invited it).
|Jan-20-12|| ||Shams: Why is the Torre Attack rarely played anymore?|
|Jan-20-12|| ||morfishine: <WiseWizard> Thanks for the reply! You commented <On your first diagram you wrote 40...Qe4 saves black, but white has the deflection 41. Rf6+> I almost fell into that myself but <40...Qe4+> is check to the white king forcing the trade of Queens. Good looking though! :)|
|Jan-20-12|| ||paulalbert: I didn't think this was as hard as usual for Friday. Preventing mate on h2 requires a series of continuous checks. The key is putting the N on the right square f5 for the discovered check and then forcing the black K to f8 so the Rd8ch is mate. Of course as always in these puzzles, as opposed to playing a game yourself, it helps to know you have something decisive to discover.|
|Jan-20-12|| ||Honza Cervenka: Euwe went astray with 27...Qd4+?! (27...Rd4 wins at least a Pawn with advantage) and 28...Qxd5? (For example, 28...Rc1! 29.Rxc1 Rxc1 30.Rxc1 Qxd2 31.Rg1 Bxd5 and black is not worse). He apparently missed the winning counter-attack and lovely final combination of white then. Despite of brilliant finish it was quite lucky win for Vidmar.|
|Jan-20-12|| ||tivrfoa: Queen moves at 16, then stays there until 37!! very cool. =)|
|Jan-20-12|| ||WiseWizard: <morfishine> Touche. I like how your logic led you to the right move, the game is simpler when you have correct logic.|
|Jan-20-12|| ||ku0826: Four pieces attacks Black King in order, Rook,Queen and another Rook.
Its the just mating line.|
|Jan-20-12|| ||bachbeet: Got it.|
|Jan-21-12|| ||Pawn and Two: In the tournament book, "IV Internationales Schachmeister-Turnier Karlsbad 1929", Brinckmann indicated 26...a5 was incorrect, and stated that Euwe had recommended 26...g4, or 26...R4c5 as stronger moves.|
Fritz clearly indicates that 26...a5! was Black's best choice: (-1.53) (27 ply) 27.Qe3 R4c5 28.b3 Rxd5 29.Bd3 Rdc5 29.Bd3 Rdc5 30.Qf2 Qd8, or (-1.55) (27 ply) 27.b3 R4c5 28.Qa4 Bxd5 29.Qg4 Bb7 30.Bd3 d5, with each variation giving Black a strong position and material advantage.
The move 26...g4, would provide only an equal position: (.00) (26 ply) 27.hxg4 Qxb2, (or 27...a5 28.Be4 Rb4=), 28.Qxa7 R4c7 29.Qa4 Bc3 30.Re8+ Kg7 31.Rxc8 Rxc8.
Brinckmann and Euwe's other recommendation, 26...R4c5, does give Black some advantage: (-.42) (26 ply) 27.b4 R5c7 28.b5 Ra8 29.Be4 a6 30.Qe3 Rc5 31.Nh2 Qd8, or (-.49) (26 ply) 27.Qxa7 Bxd5 28.Qxb6 Qxb2 29.Qxb2 Bxb2 30.Be4 Bxe4 31.Rxe4 Ba3.
Brinckmann overlooked Euwe's error at move 27, and indicated that if 27...Rd4, then naturally 28.Ne4 could follow.

Instead of 27...Qd4+?, Euwe should have played 27...Rd4!, obtaining a material advantage, with winning chances: (1.66) (26 ply) 28.Qe3 Bxd5 29.b3 Bb7, (-1.70) (26 ply), 30.Bd3 Qe5 31.Qxe5, (-1.77) (27 ply) 31...Bxe5 32.Nxc4 Bg3.
Brinckmann's recommendation 28.Ne4, is Fritz's 2nd choice. This move provides Black with strong winning chances: (-1.80) (26 ply) 28.Ne4 Qe5 29.Qf3 Bxd5 30.b3, (-2.17) (27 ply) 30...Kf8 31.Rxd4 Qxd4+ 32.Qf2 Re8 33.Qxd4 Bxd4+ 34.Kf1 Bc6 35.Bd3 d5, or (-2.00) (27 ply) 30...Rxd1 31.Rxd1 Bb7 32.f6 Bxe4 33.Bxe4 Bxf6.
At move 28, Euwe still had some advantage, but a draw seems the likely result after: 28...Rc1! 29.Rxc1 Rxc1 30.Rxc1 Qxd2, (-.61) (28 ply) 31.Rg1 Bxd5 32.Qd3 Qxd3 33.Bxd3 Bxb2.
After 28...Qxd5?, I believe Black has a lost ending, but he could still have offered stiff resistance with 30...Qc6! 31.Qxd6, (2.24) (27 ply) 31...Re8 32.Qxc6 Bxc6 33.Nc3 Rxe1+ 34.Rxe1 Kf8.
Brinckmann noted that both players were in time trouble, as they approached the first time control of 2 hours in 30 moves. Euwe's 30...Qxf5 shortened his resistance, but with the time control reached, Vidmar had time to construct the beautiful ending that we still enjoy to this day.
|Jan-21-12|| ||Pawn and Two: In my last posting, the paragraph just below the diagram should show Fritz's evaluation as: <(-1.66)> (26 ply) 28.Qe3 Bxd5 29.b3 Bb7, not <(1.66)>.|
|Apr-23-13|| ||SeanAzarin: Saw this in Horowitz & Reinfeld's book "Chess Traps, Pitfalls & Swindles." According to H&R, 28... R(5)-B2 was the move to maintain Black's winning position, instead of the unnecessary Exchange sacrifice Euwe actually played.|
|Mar-13-16|| ||TheFocus: This game shared the second and third brilliancy prizes with Maroczy - Canal - <American Chess Bulletin>, September-October 1929, pg. 151.|
|Jun-22-17|| ||Eduardo Bermudez: I like it, I like it like that|
