| Apr-13-06 | | kevin86: I hit this one right on the button: with ♘d2 black has a direct threat on the rook and a mate threat at g2. If 26 ♗xb7? ♘xf1+ winning the queen
After the text,black ends up a rook and two pawns for a lone bishop 27 ♖xg2 ♘xf1+ 28 ♔h1 ♗xg2+ 29 ♔xg2 ♘xe3+ 30 ♗xe3 |

| Apr-13-06 | | EmperorAtahualpa: Found the puzzle again! A very good week for me, so far.... I spotted Nd2 in about 10 seconds, I needed another 30 seconds to find Nf1 and I needed another minute to be sure that all variations work. |
|
| Apr-13-06 | | itz2000: 0.00001 seconds! |
|
| Apr-13-06 | | chessic eric: So I wanted 25...Qxg2+ to work out also, but it didn't. Then I found 25...Nd2 (which had been part of failed mating attempts after 25...Qxg2+) but continued differently than in the game. I felt that white's 26.Rg1 doesn't really defend f1 due to 26...Nf1+! 27.Rxf1?,Qxg2#, so I played 26...Nf1+ instead of the Queen "sac". I think it improves on the text, but I'm at work and can't analyze all possible variations just yet. Here is what I would consider the main idea: 25...Nd2!
26.Rg1,Nf1+!!
27.Kh1,Nxe3
and then either 28.Bxb7,Rd1 29.Bxe3,Rxg1 30.Bxg1 playing with queen versus bishops or 28.Bxe3,Bxg2 29.Rxg2, trading a knight for the white queen. Lemme know if I missed anything, or even better, if anyone can demonstrate how the ending with white's bishops versus the black queen is harder to win than the ending Taimanov forced with rook versus bishop. |

| Apr-13-06 | | Sleepyeyeguy: I saw 26.Rf2 instead of Rg1.. is there a significant difference?
By the way, I really enjoyed this puzzle, and don't usually look things through.. this I finally saw after taking the time to look more than 2 moves ahead |
|
| Apr-13-06 | | YouRang: <chessic eric> If 25...Nd2! 26. Rg1 Nf1+, what do you do if 27. Bxf1? |
|
| Apr-13-06 | | dwbh: <sleepyeyeguy>I don't see a difference between 26...Rf2 and 26...Rg1. The rook is compelled to capture the queen after 27. Qxg2 either way, so the rook ends up at g2 both ways. |

|
| Apr-13-06 | | TaricHall: Absolutely beautiful combination. |

 | | beenthere240: <YouRang>
if 27. Bxf1, you just say, "J'adoube," take your last move back and play 26...Qxg2+! |
|
| Apr-13-06 | | Paintbucket: I looked at a queen sac first, saw nothing, and then spotted the bishop at b7. The queen was aimed at g2 just like the bisbop would be. I had to get the knight out of the way and found 25. ...Nd2! Great game. |
|
| Apr-13-06 | | Rawprawn: itz2000 what took you so long? Planck time for me on that one. |
|
| Apr-13-06 | | YouRang: <beenthere240><if 27. Bxf1, you just say, "J'adoube," take your last move back and play 26...Qxg2+!> I always wondered what "J'adoube" means, and now I know: "I cheat!". ;-) |
|
| Apr-13-06 | | itz2000: <Raw..> I love you 2 ;) |
|
| Apr-13-06 | | TheUnkraut: Nice combination by taimanov |
|
| Apr-13-06 | | pawntificator: I Still think 25 Rd2 is a good move.
<OBIT>, after your line, (25...Rd2 26. Bxe4 Bxe4 27. Rg1 leaves everything hanging.) black can continue 27...Rd1 threatening mate if white takes the queen or the rook. Someone please show 25...Rd2 is no good.
|
|
| Apr-13-06 | | Alex S.: Proud of myself today... except for the minute in which I thought it was white to play. Came up with Rg1, which I was pleased with...
Then saw it was black to play and found it in about fifteen seconds. |
|
| Apr-13-06 | | YouRang: <pawntificator> <25...Rd2 26. Bxe4 Bxe4 27. Rg1 ... black can continue 27...Rd1 threatening mate if white takes the queen or the rook.> I don't see the mate after 28. Rxg6. If you're looking at ...Rh1, that's not mate (Kg3). |
|
| Apr-13-06 | | crafty: 25...♖d2 26. ♗xe4 ♗xe4 27. ♖g1 ♖c2 28. ♖xg6 ♗xg6 29. ♔g3  (eval 2.35; depth 14 ply; 250M nodes) |
|
| Apr-13-06 | | chessic eric: <You Rang> a good point - dunno how i missed it. Serves me right to think I improved Taimanov's play. The lesson here is write these "great" ideas down and check them after work rather than try to get them posted on the sly while the boss ain't looking... |
|
| Apr-13-06 | | YouRang: <chessic eric> What's the fun in that? :-) I think this is the trickiest part of the puzzle. We know that White can't allow ...Nf1+, and after 26. Rg1, the f1 square *looks* well covered by (1) the bishop and (2) the rook. But after 26...Qxg2 (poof goes the bishop) and 27. Rxg2 (poof goes the rook), all of a sudden it's 27...Nf1+ after all. |
|

| | OBIT: <Pawntificator> In trying to work this out in your head, I think you are forgetting the g3 square is no longer covered after the knight comes off. After 25...Rd2 26. Bxe4 Bxe4 27. Rg1 Rd1 28. Rxg6 Rh1+ 29. Kg3 - no mate here. |
|
Apr-13-06
| | OBIT: <YouRang>: Evidently, <beenthere> studied under Matulovic, who earned the nickname "Jadoubovic" for this infamous game: Matulovic vs I Bilek, 1967 Oh, and I see you responded to pawntificator well ahead of me... sorry about that. |
|
| Apr-14-06 | | pawntificator: Ok, thank you very much everyone! |
|
| Apr-27-06 | | patzer2: Black's discovered attack 25...Nd2!! threatens both mate and a decisive knight fork after 26. Bxb7? Nxf1 . White tries to defend against both threats with 26. Rg1, but White's decoy Queen sacrifice 26...Qxg2! proves White's Rook to be an over worked piece and forces the winning Knight fork anyway. |
