Nov-22-06  cjhasbrouck: Significant material without compensation is always enough to call a game.

Especially in a puzzle.

  thegoodanarchist: I cannot believe Moroczy's play on the last few moves - where is his sense of danger? With the pawn controlling the mate square g2, he should have been wary.
Premium Chessgames Member
  Peligroso Patzer: This has got to be the game of a lifetime for this otherwise obscure player.

In the following game, he succumbs to a Dobias sacrifice: J Dobias vs O Tenner, 1913

  thegoodanarchist: So the first game in the db for Ragozin is from 1927, but this game was played in '26. Yet it is still called the Ragozin defense.

I suppose Tenner wasn't prominent enough to have it named after himself?

  Peligroso Patzer: <think: I thought this was tough for a Wednesday. It just seems like there isn't anything forcing in the position.> This actually was a good position to use the Silman "fantasy" method - imagine the position you want and then try to find a way to reach it. With the Black pawn on f3, my first thought was, "If only I could get the Black Queen to g4 ...". It was then not difficult to spot e6 as a transition square to g4 to which the Queen could move with tempo.
Nov-22-06  Fisheremon: <Mazettakos: Ok Qe6 is the obvious move, but with 18.Bxf6 white surrenders immediately. I found as best defense (no fritz use, correct me if I am wrong) 18. Bxh7+ with the idea if 18..Nxh7 then 19. Bh4 so as to reply to 19...Qg4 with 20. Bg3. If black replies with 18...Kh8 then 19. Bf5 Qxe7, ok much better than what white obtained in the game> After 19. Bh4 quite unpleasant 19...Ng5.

  kevin86: I missed this one-First it took me a while to realize that black was to win. The move I finally saw was the correct move-but I thought it was a trap FOR BLACK. I didn't realize how powerful that lone black pawn could be-WITH a ROYAL escort.
Nov-22-06  Helloween: Easiest puzzle ever.
Nov-22-06  greensfield: Missed this one completely. Anyway can white find a better response than 18. Bxf6? What about 18. Qd1 Qxe7 19. Qxf3?
Nov-22-06  Stellar King: Got this one too!!.. remember my four rules!!!!!

  YouRang: A rather simple problem, and I solved it pretty fast once I considered black's pawn on f3. But 17...Qe6 is the kind of move you can overlook if you start off by looking for a more direct king attack.

Here, we use indirect path, stopping to threaten the bishop -- but only to gain the time and position for launching the *real* attack on the king.

Nov-22-06  Stonewaller2: <greensfield> yeah, or something like that. I was looking for something more violent for Black like 17. ... fg 18. ♔xg2 ♕c6+ followed by ... ♕f3 and mobilizing the ♘s and ♗ but that seemed a little longish for a Wed. puzzle. If I were Maroczy caliber I'd soldier on with a ♖ against two ♘s. But 17. ... ♕e6 does look best.
Nov-22-06  GPawn: 18. Bf5 stops mate but loses Bishop!

  Willem Wallekers: I wanted to play Qe6, but thought it didn't look spectacular enough to be the solution to a puzzle.
Premium Chessgames Member
  egilarne: Strange - saw that Qg6 would be crushing, were it not for Bxg6 - and unable to detect Qe6 and Qg4 - probably something to learn from :)
Nov-22-06  lvlaple: Heh. I got it! Of course, I thought it won a bishop, although White decided it would cost him the game too.
Nov-22-06  Trouble: This was a long combo that the GM appears to have miscalculated...of course in 1926 he might not have been a gm...good beginner problem from the diagram position
Nov-22-06  TTLump: after 17 ... Qe6, white's best line is

18. Qd1 Qxe7
19. Qxf3 Qd6
20. Rfd1 Nf8
21. h3 Qd5
22. Qxd5 Nxd5
... etc.

and up the exchange plus a pawn shouold be an easy win for black

Nov-22-06  The17thPawn: Swing and a miss, strike two hundred and twelve
Nov-23-06  vibes43: Was looking at this earlier while in a sleep deprived conditon. Considered Qe6 but couldn't evaluate all the responses along with other 17....? possibilities. Good puzzle.

  Gregor Samsa Mendel: <Peligroso>--Tenner's game of a lifetime was probably the following: Field vs O Tenner, 1923. I remember it from Horowitz's "The Golden Treasury of Chess."

  MissScarlett: According to Helms in <The Brooklyn Daily Eagle>, of February 4th, 1926, Maroczy resigned after 17...Qe6.
Apr-04-18  Alan McGowan: From the May 1929 British Chess Magazine, p. 189:

'Oscar Tenner, in a note in The American Chess Bulletin for March, takes exception to a variation of the Queen's Gambit Declined given in E.D. Bogoljuboff's recent work Die Moderne Eröffnung, and called by him the "Manhattan variation." Tenner says that the mistake Bogoljuboff makes is identical with Alekhine's in the book of the New York tournament of 1927, in connection with the game Maroczy v Tenner in the Manhattan CC championship 1926, and mentioned in a note to the game Alekhine v Vidmar.'

The game is then given (with the move order 8...Qa5 9.0-0 Bxc3 10.bxc3 c4 11.Bc2 Qxc3 - all moves changed to algebraic notation) with White resigning after 17...Qe6.

"For obvious reasons," says Tenner.

"The world champion and his challenger assert that 17.Bb4 fxg2 18.Re1 should win for White, because of the threatened sacrifice Bxh7+! With all due respect, both of these great masters are wrong!

"Black's reply to 18.Re1 is Qc6! If then 19.Bxh7+ Nxh7 20.Re8+ Ndf8 21.Qe1, with the threat (after 21...b5, for instance), 22.Bxf8 Nxf8 23.Qe7 and Black is defenceless.

"But Black has a threat of his own, which both of the great masters overlooked, and that is 21...Ng5! Then follows 22.Rxf8+ Kh7, and the only defence White might try is 23.Qe3 Nh3+ 24.Qxh3+ Bxh3 25.Rxa8 c3! and White is defenceless against either Qc4 or, in case of 26.f4 Qf3! with mate on f1.

"It seems to me that the moves recommended by the champion, 11.Bc2 and 12.Qb1, are the cause of the disaster. Black almost by force gets three Pawns for the Exchange, and that is more than any chessplayer could ask for. The only justification for such a material sacrifice would be an attack leading to certain mate, but Black's position is too strong for that.

"Bogoljuboff suggests a much better continuation for White in this remarkable variation: 9.Qc2 c4 10.Bf5 0-0 11.0-0 Re8 12.a3 Bxc3 13.Qxc3 Qxc3 14.bxc3 etc."

  FSR: Apparently Tenner specialized in mating attacks with g2 as the focal point. See also O Field vs O Tenner, 1923.

  OhioChessFan: 14 years later, I thought of the pun "Dobias Sacrifice" and found this mention of it.
