w

Study by O.Wurzburg & W. Shinkman, 1918

White plays and attains domination in 16 precise moves, no less against best defense, as under.

1. Re7+ Kd8 2. Rd7+ Kc8 3. Rc7+ Kb8 4. Rb7+ Ka8 5. Ra7+ Kb8 6. Rhb7+ Kc8 7. Rf7 Kb8 8. Rad7 Kc8 9. Rde7 Kd8 10. Rb7 Kc8. 11. Rfc7+ Kd8 12. Rg7 Kc8 13. Rbe7 Kd8 14. Ref7 Ke8 15. Rb7 ~ 16. Rb8(g8)X.

The precise maneuvers of the Rs do not allow Black any breathing space and Black pieces cannot come to the aid of their K.

Apr-22-11  cyclon: I didn't see 31.Rxh7+ and 32.Rh8+. A great combination by O. Panno and what an opponent!
Apr-22-11  SufferingBruin: <I usually only allow 2-3 minutes for ANY problem ... except Sundays, where 30 minutes (or more) is the norm.>

That's fast. I've been trying to give myself 3 minutes for each day: Monday gets three, Tuesday gets 6, etc. Solving this one in 2-3 minutes... impressive.

Apr-22-11  newton296: took me about 1 hour to find Nxe5! good stuff.

  eternaloptimist: I saw 28.Nxe5! but I thought 29.Qxe5 was the next move. Oh well...
Apr-22-11  gofer: The difficulty today was that white's position is so strong that almost every single move seems to be winning. But my guess for the best of them would be...

28 Nxe5 fxe5
29 Rxg7+ Kh8
30 Qxe5 Nf6
31 g5! winning

Time to check.

Apr-22-11  knight knight: White to play, pawn up.

I think 28. Rxg7+ Kh8 29. Qa2 is probably winning.

I've also looked at 28. d6 (opening the a2-g8 diagonal) and 28. Bxe4, however I see no clear wins in these lines.

The best move I can find is 28. Nxe5 threatening 29. Nxg6.

a) 28...fxe5 29. Qxe5 Rxb7 30. Rxb7:

i) 30...Nf6 31. g5 Nd7 32. Qe6+ Bf7 33. Qxd7 with three-pawn advantage

ii) 30...Qf8 31. Bxe4 Bxe4 32. Qxe4 with three-pawn advantage.

b) 28...Rxb7 29. Qxb7 Qf8 30. Nxg6 hxg6 31. Bxe4 bishop + two-pawn advantage.

Black can throw in a Rc1 check but white's king is pretty safe on h2.

Apr-22-11  gofer: I seem to be alone in liking <28 Nxe5 fxe5 29 Rxg7+ Kh8 30 Qxe5 Nf6 31 g5!> What's more, everyone seems to be assuming that in the line <28 Nxe5 fxe5 29 Bxe4> that black can and should rely <29 ... Bxe4!> Why???

<29 ... Rxb7 30 Qxb7 Qf8 31 Bxg6 hxg6>

is not nearly as horrendous as the line actually played! But okay things are a little difficult after the following...

<32 Qe7 Qxe7>
<33 Rxe7> winning yet another pawn!

But this not as clear cut as letting the knight stay on the board and then crucify it if it goes to f6! What I also like about <28 Nxe5 fxe5 29 Rxg7+> is that <29 ... Kf8> is even worse for black!! <30 Qxe5 Nf6 31 Qe6! (threatening 32 Rf7+ Bxf7 33 Qxf7#) Qe8 32 Qxf6+ Bf7 33 Raxf7+ Qxf7 34 Qxf7#>

So think that black ends up playing as follows;

<28 Nxe5 fxe5>
<29 Rxg7+ Kh8>
<30 Qxe5 Qf6!>
<31 Qxf6! Nxf6>
<32 f4! ...>

White has 4 connected passed-pawns and control of the seventh rank and all black has is its inactive knight! A fair trade!

  LIFE Master AJ: Can you imagine ANYONE defeating Spassky in such a fabulous manner ... ?
Apr-22-11  TheTamale: Wow! Very interesting. I have no hope of solving these... I'm just happy if I can understand why the winner did what he did. :-)
Apr-22-11  D4n: My first thought was Rxg+, however it is a poor move. Opens the Queen to attack and other not such fun stuff. Deciding the Bishop on g6 is the problem, it becomes simple to look for a way to remove the threat.Nxe5, fxe5 to save the bishop. I would have considered taking the pawn on e5 with the queen, but the causes complications with the black queen moving to f8 and defending the g7 square. Long story short, the knight is also a problem so that goes as well.

  sevenseaman: Hi<SufferingBruin>. You heard about a 'pinch of salt'?

It comes in handy. Only, at times, it takes spoonfuls.

I can 'get' nothing in 2-3 minutes. I can either look at the puzzle or the clock and its usually the latter I forget about.

I take my time. I've 24 hours allotted and it comes in within that block. No prizes whether I do it in 10 seconds or 10 hours. The only person I've to please is myself; the impersonal nature of these puzzles sees to that.

Whenever I try (foolishly)to fool people they turn out to be smarter. On this forum it is a given, in any case.

My motto: 'Enjoy your leisurely life; no fast lane is worth a trade off with it.'

  LIFE Master AJ: I normally allow only 2-3 minutes for weekly puzzles ...

I took at least 10 minutes on this one, maybe a whole lot more. (Unaccountably, I completely lost track of the time. This also has happened a few times in tournament chess ... the last few years. Nearly every time that it has happened, I lost the game.)

The million dollar question would be: WHY!???

  M.Hassan: "Difficult" White to play 28.?
White is a apwn up.
There is a way to open up the long diagonal that is occupied by White Queen and that it requires sacrifice but gives White leading edge:

28.Nxe5 fxe5
29.Bxe4 Bxe4
30.Rxg7+ Kh8 <if...Kf8 31.Qa3+ Ke8 32.Re7+ Qxe7 33.Qxe7#>

Now it is a crucial moment for White because if he stalls his attack by say <31.Qxe5 to give a discovered check next move, Black obtains the opportunity to start his assault by playing: 31....Qd1+ 32.Kh2 Qh1+ 33.Kg3 Qg2+ 34.Kf4 Qxf2+ 35.Kxe4 Qxe2+ 36.Kd4 RB4+ 37.Kd5 Rb5+ and White Queen is lost>

Therefore,White continues his attack after move 30 by playing: 31.Rxh7+ Bxh7
32.Qxe5+ Kg8
33.Qg7#
Time to check

  TheBish: Panno vs Spassky, 1955

White to play (28.?) "Difficult"

I didn't think this was too difficult, but maybe I'm missing something.

28. Nxe5! grabs a pawn while attacking the bishop, defender of the knight. Let's look at some possible continuations:

A) 28...Rxb7 29. Qxb7 Qf8 (forced) 30. Nxg6 hxg6 31. Bxe4 wins a piece.

B) 28...fxe5 29. Bxe4 Bxe4 (else White wins on material) 30. Rxg7+ Kh8 (or 30...Kf8 31. Qa3+ Ke8 32. Rg8#) 31. Rxh7+! Kg8 (or 31...Bxh7 32. Qxe5+ leads to mate) 32. Rh8+! Kxh8 33. Qxe5+ and mate in a couple, if Black chooses to throw in his queen.

C) 28...Nd6 29. Rxg7+ Kh8 30. Nxg6+ hxg6 31. Qd2 g5 32. Qd3 f5 33. Rh7+ Kg8 34. Rh8+ Kxh8 35. Qd4+ Kg8 36. Qg7#.

Apr-15-12  lemaire90: Wow, the power of the 7th rank. A rook and a minor piece could be sacked to shred the defense around black's king and leave the poor piece completely naked.
Mar-24-13  Conrad93: "28. Nxe5! grabs a pawn while attacking the bishop, defender of the knight. Let's look at some possible continuations:"

This comment is a sign that you have no idea why white played 28. Nxe5.
