| Jan-22-12 | | LoveThatJoker: <SuperPatzer77> Ka-bloo-EY to you, my friend! Viva Anand! In my humble opinion, the greatest of all chess champions! I will always have a special place in my heart for Capablanca and Petrosian as well. :) LTJ |

 | | Pawn and Two: <LoveThatJoker> If one tries to force the win in the 15.Qxh6+! Kxh6 16.Nxf7+?? line, with your suggested continuation 22.Rf1 Bf3! 23.Nxe8??, (taking the draw with 23.Nd5+ is necessary), 23...Raxe8 24.Bb3, then Black has a winning position, and a very convincing continuation is 24...Be3!. |
|
| Jan-22-12 | | LIFE Master AJ: No credit today ... I went over this game a while back, (maybe just about a week ago); I was working on my game collection for Tarrasch. It IS a pretty Q-sack, however! |
|
| Jan-22-12 | | LoveThatJoker: I would like to add that after 22. Rf1+ Bf3 23. Nxe8+ Raxe8 24. Bb3, Black has 24...Nd3!!, when 25. h3 is forced yet losing!. For 25...c1=Q+ 26. Rxc1 Nxc1 27. Rxg4 Nxb3 is winning for Black Position after 27...Nxb3

| Jan-22-12 | | LoveThatJoker: <Pawn and Two> I was in the process of correcting my line when you posted, look at my version of how 24. Bb3 loses! But look at 24. Bb5!

| | Pawn and Two: <LoveThatJoker> In the variation 22.Rf1+ Bf3! 23.Nxe8+?? Raxe8 24.Bb3, Black would be throwing away the win with 24...Nd3??. After 24...Nd3??, White could win by taking the Bishop, 25.Rxf3+. Instead, in this variation, Black has a strong winning move in 24...Be3!. In the variation 22.Rf1+ Bf3! 23.Nxe8+?? Raxe8 24.Bb5, Black still has a winning position, and maybe his best looking, and winning move is again 24...Be3!. |

| Jan-22-12 | | LoveThatJoker: <Pawn and Two> You're right. Unfortunately after 24. Bb5 the lines I'm seeing involve endgames where White is tied down to passive defence due to the Black's constant threat of promoting, furthermore it seems that even if White's K were lucky enough to make it to d2, Black's K will have much too much time available to him to mop up. As for the 24...Nd3?? line you are also right. I was actually looking at your diagram, in your original post, and for some reason I had forgotten that in the line we were debating that the B was on f3 and not on g4. I solve my puzzles blindfold (just like your avatar, Pillsbury, who is one of my heroes), so I just got my diagrams confused on the 24...Nd3 line. All in all, with best play the 16. Nxf7+!? line with best play leads to a draw with best play. That was not my intention, my intention was to win. So I must humbly retract all my statements about how I went 7 for 7 this week, or even 6.75 out of 7. I'll give myself a .25 for today, just for coming up with a wickedly unique line with plenty of pitfalls for Black and because it doesn't lose for White, even with best play. But still, now that you've brought Black's defenses to my attention, I must admit that today's puzzle for me was a failure. Oh well, I'll pick it up next week in earnest.
Truth and objectivity! Woohoo!
Pillsbury and Anand. Right on!

| Jan-22-12 | | LoveThatJoker: PS. I will also say that 16. Nxf7+ looks more to me like: 16. Nxf7+!? ?!

| Jan-22-12 | | CHESSTTCAMPS: In this middlegame attacking position (probably from a King's Gambit or Vienna Game), white is down two pawns, but has the weakened black king position under heavy pressure. I'm sure many/most of the regulars here recognized the king hunt situation and found 15.Qxh6+ quickly, as did I. However, I got stuck on the continuation 15... Kxh6 16.Ne6+ (to control the retreat square g7) Kh5 (Kg6? 17.Rf6+ and mate next) 17.Nef4+ Kh6 and couldn't find a clear win. So I finally dropped my focus on 16.Ne6 and it came together: 15.Qxh6+! Kxh6 (otherwise 16.Qxh7#) 16.Nxf7+! and with white's swarming minor pieces, black has difficulty avoiding quick checkmate, even with g7 available: A) 16... Kh5 17.Nf4+ Kh4 18.g3#
B) 16... Kg7 17.Bh6+ Kg6 (Kg8 18.Nf6#) 18.Rf6+ Kh5 19.Nf4+ Kh4 20.Bg5# (or g3#) C) 16... Kg6 17.Rf6+ Kg7 (Kh5 18.Rh6#) 18.Bh6+ Kg8 19.Rg6+!! Kxf7 20.Rg7+ Ke6 21.Nxc7+ Kf6 22.Rf1+! Nf3 23.Nxe8+! Rfxe8 24.Rxg4 wins the pinned Nf3 leaving white a bishop up, and the c2 pawn must fall. (24... c1=Q 25.Bxc1) C.1) 19... hxg6 or Nxg6 20.Nf6#
C.2) 22... Bf3 23.Nd5+ Ke6 24.Nf4+ Kf6 25.Nh5#
C.3) 23... Raxe8 24.Rxg4 Ke7 25.Rxf3 seems simplest, keeping an extra piece and control of c1. (25.Bxf8+ Rxf8 26.gxf3 Be3, forcing 27.R4g1) Maybe I've missed a mate, but line C seems to get the job done against best defense. Time for review and a Crafty test.... |
|
| Jan-22-12 | | CHESSTTCAMPS: I was right the first time, but missed the mate. Line C.2 of my analysis is flawed, because I missed 25... Qxh5 - the old "retained image" problem of a phantom pawn on f7. If white goes into line C, apparently, he must take a perpetual with 22.Nd5+ Ke6 23.Nc7+. A good Sunday puzzle for testing visualization and I ended with a miss. |

 | | Honza Cervenka: <izimbra><Interestingly enough, mate was forced after 13...Bg4 whereas black still has a large advantage after 13...Neg4 (though 12...Kh8 was also a mistake).> Well, 12...Kh8 was a mistake but not trivial one. Black apparently saw the threat 13.Nf6+ gxf6 14.Qxh6 fxg5 15.f6 with unavoidable mate. 12...Neg4 was objectively much better but black then must be able to see that after 13.h3 c6 he is fine, which is not so obvious at first glance (of course, 13...Nf2+ is no good for 14.Rxf2). Also 12...Qd8 was a better reaction on above mentioned threat of white as after 13.f6 Bg4 white has no forced win like in the game. But white still has quite powerful attack and black must defend very precisely and carefully to keep the advantage given by initial Rook odds. On the other hand, 12...Kh8 and 13...Bg4 are bad only because of stunning mating combination of white. |

| | Honza Cervenka: If 13...Neg4, then 14.h3 looks quite well. |

 | | SuperPatzer77: I'd like to say "many thanks" to <Once> and <LoveTheJoker>!!! 15. Qxh6+!! Kxh6, 16. Ne6+!! (stronger than 16. Nxf7+??) Kh5, 17. Ndf4+ Kh6, 18. Ne2+! Kh5!? (instead of Romberg's actual move - 18...Kg6), 19. Rf5+!! (We all missed 19. Rf5+!!!) - See diagram below: 
click for larger view19...Bxf5, 20. Ng3+! (clearing the d1-h5 diagonal) Kh4, 21. Bg5+ Kg4, 22. Be2+ Nf3, 23. Bxf3# 19...Bxf5, 20. Ng3+! Kg6, 21. exf5+ Kf6, 22. Bg5#!
Black tries to avoid accepting the White Rook capture (19...Bxf5) as follows: 19...Kh4, 20. g3+ Kh3, 21. N2f4# or N6f4#
19...Kg6, 20. Rf6+! (threatening Rh6#) Kxf6 (forced), 21. Bg5+ Kg6, 22. N2f4# Awesome combos by Tarrasch!!!

| Jan-22-12 | | CHESSTTCAMPS: <<Superpatzer> <You take a look at 17. Ndf4+ (not 17. Nef4+??)> Yes, actually, I intended to type 17.Ndf4 instead of 17.Nef4 - my preamble said "16.Ne6+ (to control the retreat square g7)", so obviously it would not make sense to release control of that square on the next move! Nonetheless, I did miss the correct follow-up in this line, so thanks for the note. BTW, the line I chose *almost* works, but for one key oversight, and that line involved visualizing ahead almost 20 ply, which I do with a fairly good rate of success. |

click for larger view Not only does 13...gxf6 lead to mate as you say, (though maybe 14.Qxh6 fxg5 15.Bxg5 Ng4 16.Bf6+ Nxf6 17.Qxf6+ Kg8 18.Rf4 etc), but black cannot extricate his queen eg 13...Qc6 14.Ngxh7 Bxf5 (seems to be as good as anything) 15.Rxf5 Be3 16.Bxe3 Qxc4 17.Bxh6 leaves

What a combination by Dr. Tarrasch! |

 | | scormus: <notyetagm: Fischer did say that Tarrasch's chess was "razor sharp".> If Fischer thought that he must have been, certainly borne out by the effort it took people to solve the puzzle. This is an awseome combination, which I am saw he saw right through at move 15, probably earlier. IMO the real tough part to find was the sequence beginning 18 Ne2+, seeing thet the BK was not safe on g6 |
|
Jan-23-12
| | Honza Cervenka: <sethoflagos> I think that 13.Nf6 would be hard to handle even without Ra1. It seems to be a very good alternative to Tarrasch's 13.f6, which was of course great as well. Despite of Rook odds black's position was already quite difficult. |
|
Jan-23-12
| | Honza Cervenka: For example, 13.Nf6!? Qc6 14.Ngxh7 Bxf5 15.Bxh6 or 14.Be2 with intention 15.Ngxh7 is hard to meet from black's perspective. |

| Feb-16-12 | | Mudphudder: Wow, I love playing scotch gambit. And this is just an amazing game! Queen, then rook sacs! |

 | | brankat: Brilliant, despite Black's lack of defensive skills :-) Th Rook odds didn't even play a role in this game. |

| Aug-06-12 | | chui28: ha black is 1 move from mate XD |
