 | | Phony Benoni: After <22.Nb1>:
click for larger viewA relative of the ...Rxc3 sacrifice in the Sicilian Dragon. White's development leaves a bit to be disired. |
|
| Oct-08-16 | | Aunt Jemima: I saw all the way up to 17. Re3 but couldn't see a clear way to follow up after that. I would have played this sac quickly in tournament play, just based on the ruined king side and the availability of nice attacking squares for all the pieces. It turns out that black has to be accurate and Tartakower was indeed accurate. Great attack. |
|
| Oct-08-16 | | stacase: The Rook sacrifice was the thing to do, but over the board I can't say I could have capitalized on that all the way to the win. |
|
| Oct-08-16 | | devere: 13...Rxf3 is obvious, and after that almost any reasonable continuation by Black wins. Stockfish likes 14...Qh4 best, but I think I probably would have played 14...Qg5+ followed by 15...Qf4 on Kh1 or ...Nf4 on Kf1. |

 | | al wazir: I didn't get it, but after playing the game out I think 17. Bg2 would have been better for white, and if 17...Be5 then 18. Rg1. |
|
| Oct-08-16 | | patzer2: Not so difficult for a Saturday is today's positional exchange sacrifice puzzle solution 13...Rxf3  .My follow-up after 14. gxf3 was 14...Be5! (-2.95 @ 22 depth, Deep Fritz 15). This is surely as good as the game follow-up 14. gxf3 Nf4 (-1.88 @ 23 depth, Deep Fritz 15). Perhaps the strongest winning follow-up is 14. gxf3 Qg5+ (-3.28 @ 23 depth, Deep Fritz 15). White lost the advantage of the first move with 11. dxe6 =. Instead 11. Qd2  (+0.36 @ 21 depth) maintains the tension with a slight edge for the first player. |
|
| Oct-08-16 | | nalinw: I went with
14 .... Qh4 too. The point of
14 .... Nf4 is to prevent f4 I suppose.
White was able to bring almost all his pieces to the defense but Tartakower won anyway! |
|
| Oct-08-16 | | diagonalley: the inimitable dr t at his very best! ... (i think most would play the exchange sacrifice as a matter of principle... but the follow-up is just breathtaking) |

Well, I notice that most of white's pieces are piled up on the queenside, with mainly the Nf3 guarding the king (and it is keeping black's queen away). These observations make <13...Rxf3> an interesting try, expecting <14.gxf3>

Here (following the "monkey see check, monkey give check" principle), I opted for <14...Qg5+>

Black has to move his king left or right, and either way I will follow with ...Nf4, which threatens mate. In the case of <15.Kf1 Nf4>, the N nicely seals off escape via f2, so black has to move the rook, and it looks like white loses at least the exchange: - 16.Re3 Bd4
- 16.Red1? Qg2+ 17.Ke1 Ng2+ 18.Ke2 Bh6#).
If instead <15.Kh1 Nf4 16.Rg1>, it's a little harder to see progress.

Perhaps <16...Qh5> threatening to pile up on Pf3 with Ne5. ~~~~
Looking at the game, I see that my line wasn't quite the computer favorite, but it was decent enough. |
|
| Oct-08-16 | | AlicesKnight: The basic attack ...Rxf3 with Q/N attack was not too hard to see but the continuation was less clear. The f4 blockade of White's Ps prevents easy access for defence instructively. <YouRang> <- 16.Red1? Qg2+ 17.Ke1 Ng2+....> is prevented by the Q blocking g2, surely? |
|
| Oct-08-16 | | mel gibson: Nice game - I saw the first move within 5 seconds &
there was always a follow up check from the Queen & it looked promising. |
|
| Oct-08-16 | | YouRang: <AlicesKnight><<YouRang> <- 16.Red1? Qg2+ 17.Ke1 Ng2+....> is prevented by the Q blocking g2, surely?> It would seem that I left out a move and made a typo. Deciphering my actual intent is a Sunday puzzle. :-) Following 13...Rxf3 14.gxf3 Qg5+ 15.Kf1 Nf4, I think I had <16.Red1 Qg2+ 17.Ke1 Qxf3 18.Be2 Ng2+ 19.Kd1 Bh6#> Checking this with the computer, this line actually isn't best for either black or white. Following 16.Red1, the computer recommends 16...Qg2+ 17.Ke1 Ne5 18.Kd2 Nfxd3 19.f4 Qxf2+ 20.Ne2 Nxf4 21.Kc1 Nxe2+ |
|
| Oct-08-16 | | gofer: The first move is obvious. It screams to be played. But after that the continuation
is really not clear to me, black has so many attacking moves and so many pieces
that come into those attacks that I have just looked at the most forcing line to
allow me to at least get three or four moves into the continuation... <13 ... Rxf3>
<14 gxf3 ...>
Now we have a selection of moves to choose from; Nf4, Ne5, Qf6, Qg5+ Qh4 and Bd4.
But only one threatens mate immediately...
<14 ... Nf4>
The king must move and losing Ph2 is just losing slowly and painfully, so really
white only has one choice...
<15 Kh1 Nd5>
Okay, we are three moves into the combination and already black's control of
the board and white's lack of it are creating issues. White threatens Nxf3 gaining control of the a8-h1 diagonal, which white simply
cannot allow, black also threatens to win Bd3 which is now attacked twice. White only has two solutions and Re3 gives back the exchange
far too easily.
<16 Be2 Qh4>
<17 Rg1 Rf8>
Hmmm, okay this all looks fine for black, but not for white, but in reality I am still no further forward with this one than I was at the
start.
~~~
Okay, I didn't even get white's second move right... ...not a good sign! |

 | | perfidious: <PB....White's development leaves a bit to be disired.> <PB> is obviously of English extraction (laughs), though knowing his playing tendencies, he would have had no hesitation whatever in playing ....Rxf3 either. |
|
| Oct-08-16 | | Gregor Fenrir: After <13...Rxf3 14 gf3> I went for overloading white pawns: <14... Qg5+ 15 Kh1 Qf4 16 Kg2 (16 Be2?? Be5 17 Kg1 Qxh2+ 18 Kf1 Qh1#) Rf8 17 Be2 Ne5> (three pieces are attcking a pawn on f3) <18 Qd1 Ng4! 19 Rh1 Bd4> and white is unable to defend a pawn on f2. |

| Oct-08-16 | | YouRang: <gofer><Okay, I didn't even get white's second move right... ...not a good sign!> If by "white's second move", you mean Kh1 (i.e. 13...Rxf3 14.gxf3 Nf4 15.Kh1), then you actually did better than Tartakower. According to the engines, your 15.Kh1 is better than his 14.Bf1 by about half a pawn. Your whole line after that was solid too. |

 | | agb2002: Both sides keep full material except one pawn.
Black can weaken the white castle at the cost of an exchange, 13... Rxf3 14.gxf3 Qg5+: A) 15.Kf1 Nf4
A.1) 16.Reb1 Qg2+ 17.Ke1 Qxf3
A.1.a) 18.Be2 Nxe2 (18... Ng2+ looks also very good) 19.Nxe2 (19.Qxe2 Bxc3+ wins decisive material) 19... Bxe4 and Black seems to end up two pawns ahead at least. A.1.b) 18.Bf1 Ne5 19.Rd1 (due to Nfd3+ followed by Bh6 or Nxb2) 19... Qh1 (threatens Nf3#; 19... Qxc3+ 20.Bxc3 Nf3# would be a beatiful end but White has 20.Qxc3) and Black will have at least two pans for the exchange and attack. For example, 20.Kd2 Bh6 21.Kc1 Ne2+ 22.Kb1 Nd4 traps the White queen. A.1.c) 18.Rd1 Ng2+ 19.Kf1 (19.Kd2 Bh6#) 19... Ne3+ 20.Ke1 (20.Kg1 Qg2#) 20... Nxc2+ wins. A.2) 16.Rd1 Qg2+ 17.Ke1 Qxf3 looks similar to the above lines. A.3) 16.Re3 Qg2+ 17.Ke1 Qg1+
A.3.a) 18.Bf1 Ng2+ wins a pawn at least.
A.3.b) 18.Kd2 Qxf2+ followed by Bh6 looks very good for Black. B) 15.Kh1 Qf4
B.1) 16.Ne2 Qxf3+ 17.Kg1 Bxb2 18.Qxb2 Qxd3 - + [B+N+P vs R]. B.2) 16.B(Q)e2 Be5 17.Kg1(2) Qxh2+ 18.Kf1 Qh1#.
B.3) 16.Rg1 Qxf3+ 17.Rg2 Nf4 18.Bf1 (due to Qxg2# and N(Q)xd3) 18... Rf8 looks very good for Black (emerges a pawn ahead after Nxg2 and has the better position). -----
That's all I can do today. |

| Oct-08-16 | | stst: One possible development:
13.........RxN

15.Kf1 Nf4
16.Re3 Qg2+
17.Ke1 Qg1+
18.Kd2 Qxf2+

20.BxB Ne5
21.BxN dxB
22.Rf1 Rd8+
23.Kc1 QxR(e3)+
24.Kb2 Rd2 pinning Q&K ====> WQ lost
see how different... |
|
| Oct-08-16 | | stst: Tata chose Nf4 first, before Qg5... and also White chose to hide his K to the h-file, rather to the Q-side.
Yet the main vein prevails, esp. later Ne5 and making use of the N-Q couple.
The finishing touch is rather elegant!!
IF
26.QxN Rf1+
27.Kg2 Qe2+
28.Kg3/h4 Qf3/Rh1+ will finish it off. |
