  lost in space: hmmm, after re-playing the moves 1-15 of the game, I am asking me what white can do after

15...Bd4 (instead of 15...Bxf4)

The position looks rather = to me.

Thanks John. 30-40 years ago my parents always told me I am the opposite, a slob and entropy maximiser.

Oct-03-09  WhiteRook48: I came up with 16 RxB QxR 17 Nd5 and didn't realize the e-pawn was pinned
Oct-03-09  A Karpov Fan: I thought 17...Qb8 was the best defense also, but failed to 18.Qc3! which looks like the key move to see imo as then the attack on the dark squares rolls ahead.
Oct-03-09  Eduardo Leon: Black has serious weaknesses in the dark squares. Therefore, white must remove its main defender if he wants to start a successful attack.

<16. ♖xf4 ♕xf4 17. ♘d5>

Where should the black queen retreat? After some careful analysis, the obvious <17. ... ♕b8> must be discarded, because of the sequence <18. ♕c3 ♖g8 19. ♕b4+ d6 20. ♕h4 ♔d7 21. ♘f6+>, winning a piece.

<17. ... ♕h4>

Unfortunately, this move doesn't hold the position for much longer than <17. ... Qb8>.

<18. ♖e4 ♖g4 19. g3>

Black's main threats, being based in the weakness of white's back rank, have disappeared.

<19. ... ♕g5>

Even if the queen could go to h5 (<20. ♘f6+>), it wouldn't create enough threats there.

<20. ♘c7+ ♔d8 21. ♘xc7>

White is finally a piece ahead. Is this the end of the story? Ostensibly, yes. However, black finds a last resource that, unfortunately for him, doesn't save him.

<21. ... ♖xe4 22. ♗xe4 ♕a5>

Yes, the knight is trapped...

<23. ♕c3>

... but white has seen one step further...

<23. ... ♕xc3 24. bxc3 d5>

(To play <25. ... b5>, of course.)

<25. ♗xh7>

... and white's h pawn decides the game.

Oct-03-09  antharis: My suggestion: 16. Rxf4

If 16... Qxf4 then 17. Nd5 attacks the black Queen: 17... Q(irrelevant) 18. Nc7+ wins the rook. Therefore white wins at least the black bishop.

I saw the fork between the bishop and the queen at d5 and the fact, that black cant take the knight. That leads me to the solution.

Hope its right. ^^ Time to check.

Oct-03-09  antharis: Ooops 17... Qh4 threads mate in two first. Ok. :) But i was quite right.
Oct-03-09  Athamas: <Because Black must flee with Qh4 or play 18…Rg4 19.Rxg4 Qxg4, he cannot feasibly prevent 19.Nc7+ 20.Nxa8, leaving him down B for 2P.>

This is a huge blunder and white gets mated.

19...Qe1+ 20. Bf1 Qxf1#

My attention seems to have wandered throughout the week, but this post-script is, indeed, a major blunder. I will correct the copy I make, so thanks for pointing the error out, <Athamas>.

  lost in space: Tried to find the most adamantine defence.

This is what I found with the help of Rybka:

16. Rxf4 Qxf4 17. Nd5 Qh4 18. Re4 Rg4 19. g3 Qg5 20. Nc7+ Ke7 21. Nxa8 Rxe4 22. Bxe4 Qe3 23. Kg2 d5 24, Bxh7 f5 25. Qf2 Qe4+ 26. Qf3 Qc2+ 27. Kh3 Bd7 and the position is evaluated only with +0,88 d =21. Black still can fight.

Oct-03-09  BOSTER: 16. Rxf4- deflection black Queen from "c" file.
17. Nd5 using absolute pin pawn e6
17. ...Qg5- protecting e7 and f6 squares.
18. Nc7+ K moved
19. Nxa8 and now black has the problem with his Bc8. In real game I guess white missed move 22. Qc7+ (between move).

  johnlspouge: < <lost in space> wrote: [snip] Rg4 19. g3 Qg5 >

Yes, my post-script should have included 19.g3, as <Athamas> points out. Thanks for (letting Rybka do) the work, <lost in space>.

< Thanks John. 30-40 years ago my parents always told me I am the opposite, a slob and entropy maximiser. >

My parents told me worse. In dealing with my daughters, I remind myself daily that a child reaches its full potential when it can love its parents but discount their opinions completely.

My daughters are doing fine ;>)

  dzechiel: White to move (16?). Black is up two pawns. "Very Difficult."

A late start today. Was at Dodger Stadium last night and didn't get in 'til the wee hours of the morning.

Just looking at this position, I want to play

16 Rxf4

Pretty forcing.

16...Qxf4 17 Nd5

Attacking the queen and threatening checks on c7 and f6. Of course, the e-pawn is pinned by the rook. It would seem the black queen must move, but where? The most agressive move seems to be


And if given a chance, black will play ...Qxe1+ leading to mate. This also covers f6, for what it's worth.

Now white has to be careful.

I wish I had more time to look at this, and I'll try harder this evening.

Time to check and see how this went down.


Wow. Very pretty. White really had to look deeply into this potion to ensure the sacrifice was sound.

  johnlspouge: < <dzechiel> wrote: [snip] Now white has to be careful. >

Very judicious, David, and a good way to finish ;>)

Oct-03-09  Athamas: Well as pointed out earlier as well, Qc3 is probably stronger than g3. Not because of somtehing particularly obvious, but because after g3 black can play Rxe4, which I think is very strong. If gxh4, black gets 2 rooks for the queen and still has a pawn up as well, if a bit underdeveloped. If Bxe4, I think black stands better than in the Qc3 variation, but it may be close.

  johnlspouge: Hi, <Athamas>.

At 15 plies, Toga gives as best play, with the <last move I entered>,

+1.22 P : 19.<Qc3> Qg5 20.Nc7+

+1.78 P : 19.<g3> f5 20.Rxg4 fxg4 21.Nc7+

The reason the valuation of 19.g3 is better than your valuation, is that after 19...Rxe4, Black interpolates 20.Nc7+ before capturing the Black Re4.

Oct-03-09  Athamas: I'm so confused... your 2nd variation looks like the Qc3 variation but you have g3 next to it.

19. g3 f5??

Wouldn't white just gxh4?


19. Qc3 Qg5

Wouldn't white just Rxg4?

Premium Chessgames Member
  johnlspouge: < <Athamas> wrote: I'm so confused... >

No, you are not confused. Mea culpa. Indeed, I switched the initial moves, one "benefit" of trying to edit computer variations.

The valuations are correct for the initial moves, and my point in posting was that indeed, Toga values the game variation 19.g3 more highly than 19.Qc3.

Oct-03-09  Athamas: Well, the 2nd variation is the Qc3 variation and it's the better rated variation for whtie as well... was also part of my confusion. Although I think both moves are strong enough to win just as a patzer looking at it.
Oct-04-09  TheBish: Azmaiparashvili vs Kurajica, 1995

White to play (16.?) "Very Difficult"

Material: White is down two pawns.

Candidate moves: Rxf4 is forcing and possibly strong, since it weakens all the dark squares, and after 16. Rxf4 Qxf4 17. Nd5 already threatens 18. Nc7+.

16. Rxf4! Qxf4 17. Nd5 and now:

A) 17...Qh4 18. Re4! wins, i.e. 18...Rg4 19. g3! (not 19. Rxg4?? Qe1+) Qh3 20. Rxg4 exd5 (or 20...Qxg4? 21. Nf6+ wins the queen) 21. Rg8+ Ke7 22. Rxc8 Rxc8 23. Qxc8 leaves Black with only two pawns for the bishop, and those will soon drop "like flies".

B) 17...Qb8 (to protect the rook) 18. Qc3! and now:

B1) 18...Rg8 19. Bxh7 Rf8 20. Qb4! d6 21. Qh4 f6 (21...Kd7 22. Qe7+ Kc6 23. Nb4+ Kb5 24. Qxf8 Kxb4 25. Qxf7 is an easy win with Black's exposed king) 22. Bg6+ Kd7 (or 22...Kd8 23. Qh7! mates) 23. Nb6+ Kc7 (or 23...Kc6? 24. Qb4! threatening 25. Rc1# is even stronger for White) 24. Qb4! Bd7 25. Rd1 d5 26. Rc1+ Bc6 27. Nxa8+ Qxa8 28. Qe7+ Kb6 29. Qxe6 restores material equality, with an obvious advantage for White. There may be something even stronger in this line, but no more time to analyze it!

B2) 18...Kf8 19. Qf6 Rg8 20. Rf1 mates shortly.

B3) 18...f6 19. Qxf6 Rf7 20. Qh8+ Rf8 21. Qxh7 Qd6 22. Bg6+ Kd8 23. Qh4+ and mate in 2.

  perfidious: If I had known this event was fixed, maybe I would not have sought improvements on Kurajica's play (laughs)--as it was, I analysed this game, thought I found better play for Black, then got hosed in a correspondence game anyway.
