  ajile: Wow got it. The thing I noticed was that Black's king is still in the center so how does White open the position? 15.Nxc6 destroys Black's protective pawn chain so this is what I looked at first.
Apr-16-11  newton296: before I saw Nc6 I saw fisher can win with the simple move Rac1.

Apr-16-11  VincentL: ."Very Difficult"

I see 15. Nxc6 Qxc6 16. cxd5 Q moves 17 dxe6

White gains a pawn with this, but surely there is more to the puzzle than I am seeing.

I haven't much time, so must check.

Apr-16-11  scormus: <Jim> your ... Qd7 line looks like the death of 1000 cuts for B.

  morfishine: <sevenseaman> I'm taking your advice and resting from chess. Too much lately, every day. Need to re-charge the batteries. I saw you comment on the Anand - Shirov game; appreciate it. I see you've been doing quite well with these puzzles; thats great; keeps the mind active and sharp

  Jimfromprovidence: <Scormus Jim your ... Qd7 line looks like the death of 1000 cuts for B.>

Now that I've looked over the posts more completely, I see that <patzer2> first gave the line I proposed parenthetically, so props to him.

And actually, the position after the text 17 Qc3 threatens three pieces, not two as I earlier had implied (It's both of the knights and the b rook.)

click for larger view

But still, the main threat after 17 Qc3 is 18 Qe5+, winning both the b rook and the queen (as the queen is already en prise and white will capture the rook with check).

Apr-16-11  ZUGZWANG67: I found 15.Nxc6 Qxc6 (what else?) 16.cxd5. So far so good. But I missed 16...Nc5 and the rest of the combo so I can't award myself much here. That is because if one misses 16...Nc5 than the entire solution loses it's brightness. Well, that is my opinion.

Yet I've always said to myself to always watch out for an opponent's sufficient big threat that would make one's combo collapse. That is, say, if you're threatening his Q, then, can he too threaten your's or, which could be even worse, does he have a nasty check? Obviously, I failed in my thinking process here. Gotta fix it!


Apr-16-11  ZUGZWANG67: <<sevenseaman:> Quickly saw 15. Nxc6 Qxc6 16. cxd5.

Then inexplicably did not find

16...Nc5 for the defense.>

Funnily I read your comment only after posting mine.

Hopefully this will help you reseting your own thinking process too!

  Check It Out: 15.Nxc6 Qxc6 16.cxd5 comes to mind, but not sure what comes after that
Premium Chessgames Member
  eternaloptimist: i got the moves correct up to 18.♗xc5; i chose 18.♗f4 instead, which still would give white a huge advantage (+5.36 according to houdini 1.5) & lead to a win for white as long as white plays well. although, it would definitely take longer to win w/ 18.♗f4.
Apr-16-11  mucher1: <patzer2> <If 17...Qb6, then White wins back the pinned Knight with decisive advantage after 18.b4 Qd8 19.bxc5 >

A bit crude, isn't it? 18.d6(!) looks pretty cute.

Apr-16-11  tacticalmonster: 1) White has the unopposed LSB

2) Black has an inferior pawn structure: He has weakened light square pawn complex (b5-c6-d5) and doubled f-pawns

3) White has a slight lead in development and Black king is in the center

4) b8 rook is unprotected and b5 pawn is undefended

candidate: 15 Nxc6 Qxc6 16 cxd5

a) 16...Nc5 17 Qc3 Qb6 (17...Qd6 18 Bxc5 Qxc5 19 Qxf6) 18 b4

b) 16...Nxd5 17 Bxd5 Qd7 ( 17...Qd6 18 Bxa7 Rd8 19 Qxb5+ )18 Rac1 Kd8

Apr-16-11  WhiteRook48: I didn't see the entire combination, but I saw the 15 Nxc6 and the 16 cxd5 idea
Apr-16-11  sevenseaman: <ZUGZWANG67>Absolutely yes. <CG>'s daily puzzle is a big attraction on the site. A solver is naturally thrilled at finding 'the solution', though that may not always be an absolute objective.

This craving for a solution? It is there because we seek answers to our day to day posers to arrive at a measure of clarity, to rid our cluttered minds of the cobwebs that threaten to turn our simple lives into cauldrons of pressure that in turn tend to erode our peace of mind.

Unfortunately, for some of us, brownie points or the need for one-up-man-ship gets the better of us.

We feel compelled to be seen as the 'resounding successes' rather than hapless struggling zombies we actually and more likely are in our humble efforts to gain enlightenment. We forget that 'learning on the job' is a sufficient reward by itself.

I know I'll succeed. The fear of failure does not daunt me or deflect me in my desire to learn and become better.

So thank you, your advice is well taken. My apology for the longish lecture. Perhaps I had to get it out of my system, somewhat selfishly.

Apr-16-11  stst: Yeah, it's a long sequence, so "V Diff"
but try:
15.Nxc6 QxN
16.Pxd5 NxP (here, some other Bk moves a re plausible, leading to different W attacks.) 17.Bxd5 Qd7
18.Rc1 Rc8
19.Rxc8 Qxc8
20.Qxb5+ Kd8
21.Rc1 Nc7
22.Qb6 Rh7
23.Bf4 Pf6
24.Qxf6+ Be7
25.BxN+ Ke8
26.Bc6+ Qd7
27.Qxg6+ Kf8
28.Bxd7 and Bk can resign
Tiring day again, Good Nite!
Apr-16-11  Damianx: I thought Fisher would of played 11 pawn x pawn b5 2 isolated pawns complete center domination that,s to big an advantage against Fisher but its a very young Fisher
Apr-16-11  Damianx: Ps but i guess he saw the lot
Apr-16-11  M.Hassan: "Very Difficult" White to play 15.?
Forces are equal.
Last night I spent quite a while studying 15.Nxe6 approach and got tired of seeing that it attains nothing and repairs Black's doubled pawn structure. Tonight I saw a light at the end of the tunnel by taking the c pawn:

15.Nxc6 Qxc6
and the good thing is that White's c pawn or Bishop can fork two Black pieces: 16.cxd5 Nxd5
17.Bxd5 Qd7
18.Bxe6 fxe6
19.Bf4 Rb7
20.Be5 Rh7
White is a pawn ahead and I think by doubling his Rooks will have better attacking chances. Time to check

<Fischer's Game of the Day>

Fischer vs P Lapiken, 1956

This was the first game of Fischer's (from the 1956 U.S. Open) that was ever published in Chess Life. There were no annotations. The annotations here are by Fred Reinfeld.

Bobby took 10 minutes to win.

Fischer – Lapiken, Peter
King’s Indian Attack

1.Nf3 Nf6 2.g3 d5 3.Bg2 Bf5 4.O-O e6 5.d3 c6 6.Nbd2 Na6 7.a3 Nc5 8.c4

<The key move of Reti's system. The pressure on Black's center is strengthened by this flank thrust.>


<A massive positional blunder. By undermining his c-pawn, Black undermines his hold on the long diagonal.>


<Excellent. He gains time by attacking the weakened c-pawn. Meanwhile his hitherto passive King's Bishop suddenly takes on a menacing role.>

9...Qd7 10.Nxf5 exf5

<The exchange has further weakened Black's position.>


<Now White threatens 12.Bg5, with the further threat of inflicting a tripled isolated f-pawn on Black and at the same time undermining the support of his d-pawn and still further thought the removal of Black's protective Knight. Black has nothing to hope for from 11...dxc4 12.dxc4 bxc4 13.Na5, with a winning positional advantage for White. 11...h6 12.Be3 Ne6 The alternative 12...Nxb3 13.Qxb3 d4 is refuted by 14.cxb5!. This is a good example of White's power along the long diagonal.>

13.Nd4 g6

<The alternative 12...Nxd4 13.Bxd4 Be7 15.cxb5 cxb5 16.Qb3 (threatening to win a Pawn) Rd8 17.Rac1 leaves White with all the play.>


<Very strong. As Black cannot go in for 14...dxc4 15.exd4 Nxd4 16.Bxd4 Qxd4 17.Bxa8, he must give his b-pawn additional protection. But this gives Fischer the opportunity for a neat combination.>

14...Rab8 15.Nxc6!

<What makes this sacrifice particularly delectable is that it validates the basic theme: pressure on the long diagonal.>

15...Qxc6 16.cxd5 Nc5

<Black wriggles.>

17. Qc3! Qd6

<A neat variation is 17...Qb6 18.b4 Na4 19.Qe5+ winning Black's Queen.>

18.Bxc5 Qxc5 19.Qxf6 1-0.

<An amusing finish. If Black moves his attacked Rook, White wins the other one with 20.Qe5+.> (0:10 – 1:20)
