May-01-10  gofer: <BUT, white's next move is Qb8#! So in reality black cannot allow the pawn storm and must block it with its other pieces, but unfortunately it cannot! >

What utter drivel! The king just comes across and stops the pawns and black wins!

:-(

May-01-10  DarthStapler: I had the same idea as dzechiel
May-01-10  David2009: Goglidze vs Bannik, 1954 White 44? Without the Bishops it is a book win starting g5 and a pawn breakthough. So this is the candidate move. Try 44. g5 hxg5 45 f5 gxf5 46 h5 fxe4 47 Bxe4 Bc4 48 h6 Bg8 = Instead try 44 e5 fxe5 45 f5 gxf5 46 g5 hxg5 47 hxg5 e4 48 g6 and wins. Black has other tries but 44 e5 rather than 44 g5 is the way to go. Time to check:
======
Got the first bit, missed the brilliant refutation of 47 hxg5 which LOSES for White!.

Goglidze-Bannik 1954 44? Here's the position on CraftyEGT (End Game Trainer): http://www.chessvideos.tv/endgame-t... White to play and win in this online link.

POSTSCRIPT: <Old Wolf: The annotation says 47.hxg5 loses , but it actually wins: 47. hxg5 e4; g6 Bg2; Ke1! d3; Ba8! d2+; Kxd2 e3+; Kxe3 Bxe8; Kd4 1-0> Absolutely right as the Crafty link shows. So I missed the brilliant refutation of the brilliant refutation!

May-01-10  cheeseplayer: very easy. got it in like 10 seconds
May-01-10  felixd: It's rare to find sunday's puzzle in 5 seconds, but this time it was incredibly easy...
May-01-10  JohnBoy: Without looking at solutions, right off the bat I'd play e5 then f5. The bishop on d5 seems to cover enough squares to keep the black pawns from advancing, while the queening square f8 cannot be covered by black's bishop.

  patzer2: The first possibility I looked at in solving today's Saturday endgame puzzle was 44.e5! fxe5 45.f5 gxf5 46. g5 .

However, if it had not been a difficult Saturday puzzle, I might have been tempted to look for an easier solution.

  patzer2: Out of curiousity, I had Fritz 10 analyze the position. Initially, the program gave its best choice as 44. Bf7 , while indicating 44. e5 and 44. f5 were practically equal. However, after forcing the winning line, the program, @ 20 ply, gave it's top three choices as

1. (3.43): 44.e5 fxe5 45.g5 hxg5 46.f5 gxf5 47.h5 e4

2. (2.57): 44.f5 g5 45.hxg5 hxg5 46.e5 Kc7 47.exf6 Kd8 48.Bf3 d3 49.Bb7 Bh3 50.Bxa6 Bxg4 51.Bxd3 Bf3 52.Ke3 Bd5 53.Kd4 Bf7 54.Be4

3. (1.42): 44.Bf7 Kb5 45.Bxg6 Bc4 46.h5 Kxb4 47.g5 fxg5 48.fxg5 hxg5 49.h6 Bg8 50.h7 Bxh7 51.Bxh7 Kc5 52.Bf5 Kd6 53.Kd3 Ke5 54.Bg4 Kf4 55.Be6

  agb2002: The material is even.

Black threatens ... Kb5 and ... Kxb4.

White can try to exploit his king side pawn majority with 44.g5 but after 44... fxg5 (44... hxg5 45.f5 gxf5 46.h5 g4 47.h6 g3 48.h7 g2 49.h8=Q g1=Q 50.Qb8#) 45.h5 gxh5 46.f5 Kc7 47.f6 Kd7 48.e5 (48.Bf7 Kd6) Ke8 49.e6 Bb5 followed by the advance of the g- and h-pawns.

A better option is 44.e5:

A) 44... fxe5 45.f5

A.1) 45... gxf5 46.g5 hxg5 47.hxg5 (or 47.h5) e4 48.g6 e3+ 49.Ke1 Bd3 50.g7 f4 51.g8=Q f3 52.Qb8#.

A.2) 45... e4 46.f6 (46.fxg6 e3+ 47.Ke1 Bd3 48.g7 Bh7 49.g8=Q Bxg8 50.Bxg8 Kb5) e3+ 47.Ke1 Bb5(d3) 48.f7 + -.

A.3) 45... g5 46.f6 + -.

B) 44... f5 45.h5 (or 45.g5 h5 (45... hxg5 46.fxg5 followed by h5) 46.Bf7)

B.1) 45... gxh5 46.g5 (46.gxf5 Kc7) hxg5 47.fxg5 Bb5 48.g6 + -.

B.2) 45... fxg4 46.hxg6 + -.

B.3) 45... g5 46.fxg5 hxg5 47.h6 + -.

C) 44... Bb5 45.exf6 Be8 46.f7 + -.

D) 44... g5 45.exf6 + -.

  agb2002: I missed the 48... Bg2 in my line A.1. I thought 47.hxg5 was similar to 47.h5.

Very nice and very instructive!

  Jimfromprovidence: e5 looks playable one move earlier. So if 43 e5, assuming 43 ...bxa5 44 exf6 Kd6 45 bxa5, white is in great shape.

May-01-10  VincentL: "Very Difficult".

My idea is to queen a pawn on either f8 or h8 (squares of opposite colour to the black bishop).

With this in mind I think the start is 44. e5 fxe5 45. f5 gxf5

Now the continuation is either 46. f6 or possibly the bizarre 46. g5 hxg5 47. h5

I have been playing on from the resulting positions for some time - sometimes I win for white and sometimes I do not.

There could be something I have completely missed. But I cannot see any foolproof main line, and I have got as far as I can in the time that I have.

Let's check.

May-01-10  Brandon plays: Wow, I can't believe that I actually picked out the winning line. I was trying to think of a way to deflect black's pawn so that black couldn't defend against white's pawn queening without allowing black the chance to defend. Black's king is sort of stuck in a bad position to defend against a kingside pawn advance. Excellent puzzle.:)
May-01-10  Justawoodpusher: I saw e5,f5,g5 and hxg for white, but was not sure if white could stop blacks pawns. After checking I was disappointed that hxg should not be a correct solution and I wanted to understand why and used my Fritz. And voilą, there is a win also in this line, 49.Ke1! beeing the key move.

Would I have found 49.Ke1 over the board? Probably not. Would I have anyway went for e5,f5,g5? - Most likely only in a "must win" situation.

  chrisowen: I thought it was ether gasp Bf7 or e5, laughing it off now I seen the solution. Sweet oil of vitriol gonna dump a carload of pawns so what a nit rousing g5 compounded it. Goglide fingers the gpawn but doesnt get what looks like the right key. The organic three step burn is the grinder, shoos a leg in and the hpawn tiptoes in the shadow. The spat is whether black could dance down suitably in time. One night when steps trotted out fox me early.
May-01-10  lost in space: No, saw the general idea, but the execution was wrong. Completely wrong.

Sigh

May-01-10  King.Arthur.Brazil: I've seen both solutions the game move directly g5, but as it was easy too much, and level says very dificult, obviously is not that direction. So I begin to think about sacrifice, and the triple seems plausible as h7 couldn't be stopped without any check. But, I've not seen the Kibitizing, only the game. After looking at Kibitz, I confirm the line, but dind't noticed the e3/d2 and Sg2 black moves. It's amazzing immagination to find this line during the game. I doubt one will do it.
May-01-10  tivrfoa: people saying it is easy ... come on. it's not just the move. it's the whole idea. crazy
May-01-10  wals: Rybka 3 1-cpu: 3071 mb hash: depth 15:

Black erred:-

42...b6, +3.64. better Bb5, + 0.23 or
Bh3, +0.57.

White made amends:-

44.g5, +0.07. better e5, as indicated,
calculated around +6.92.

May-01-10  Eduardo Leon: White to play. 44.?

White has a pawn majority in the kingside. The black bishop is too far away to be able to stop a potential white passed pawn. Thus...

<44.e5! fxe5 45.f5! gxf5 46.g5! hxg5 47.hxg5>

This solution is relatively easy to validate. (47.h5! is more beautiful, of course.) Now black has a clever trick to try to stop the pawn.

<47...e4 48.g6 ♗g2!>

Threatening to win the bishop with 49...e3+. Now, sticking to controlling g8 with the bishop throws away the win: 49.♗c4? e3+ 50.♔e1 d3! 51.♗xd3 ♗d5 =.

<49.♔e1! d3>

Renewing the threat to win the bishop with 50...d2+ 51.♔xd2 e3+ 52.♔xe3 ♗xd5. And, of course, 50.♗c4? throws away the win.

<50.♗a8!>

This is a real problem move. Down a pawn, white has no trouble giving up his bishop, but in a square where black's bishop cannot do anything to stop his pawn.

<50...d2+ 51.♔xd2 e3+ 52.♔xe3 ♗xa8 53.♔d4 >

The g pawn is still two squares away from promoting. However, there's nothing black can do to stop it.

---

<47.h5! e4 48.h6 e3+>

Now 48...♗g2 is pointless, since the black bishop can't stop the h pawn at d5.

<49.♔e1!>

Not 49.♔d1?? d3! 50.h7 ♗e2+ 51.♔e1 ♗g4! .

<49...♗b5 50.h7 d3>

Black's last hope: attempting to create a mating net or, at least, trying to promote his own d pawn.

<51.♗b3 d2+ 52.♔d1 ♗c6 53.♔e2 >

White's temporary threat against black's e3 pawn stops black's attempt to stop white's own h pawn. This is another case of "unfortunately, one tempo too late". If black could play two consecutive moves, those would be 53...f4 and 54...g4, and he would win instead.

May-01-10  wals: I left Rybka calculating while I had breakfast, time overall, 1 hour 45 min, depth 19.

44.e5, + 8.36.
44.f5, + 3.64.

May-01-10  Lord Osiris: Can anyone find a refuation to my 44.f5 line? black has 3 options for his 44th:

1)do nothing with the g pawn which is obviously immediately losing.

2) 44...gxf5 45.e5!,Kc7*, 46.exf6,Kd7 47.g5 and black cant stop white from queening

*if 45...fxg4, 46.exf6 and white queens first
*if 45...fxg5 46.g5! and we can see that white queens first.

so it seems that 44...gxf5 doesnt work.

3) 44...g5 45.(hxg5,hxg5) 46.(e5,Kc7) 47.(exf6,Kd6) or Kd7 etc... probably blacks best chance but still winning for white i believe. there are a ton of examples of how the game could go as it would be so many moves deep but one line could be:

48.(f7,Ke7) 49.(Bb3,Ba3) then 50.Bd1 dropping the f7 pawn but leaving the black bish out of position as it has to move back to f1 to protect the b3 square from the K. to follow would be 50...Bf1 51.(Ke1, Bb5) 52.(Kf2,Kxf7) 53.(Kf3,Kf6) 54.(Ke4,d3) 55.Kd5 and black is in zugzwang. after 55...Ke7 56.Bb3 black is in alot of trouble.

Not the best way to win but this is what i guessed before i saw the correct answer so im trying to make it work and i think it does...slowly. Any thoughts?

May-01-10  Lord Osiris: Guessed is the wrong word. Reasoned is a better one.
May-01-10  openingspecialist: I got it wrong.

I miscalulated with:
44. g5 hxg5 45. hxg5 fxg5 46. fxg5

I thought the 47. Bf7 line forced a Queen. I saw the 46. ... Kb5 47. ... Bc4 defense but i thought Be8 g6 Bf7 would take care of that. I missed the king march.

  johnlspouge: Saturday (Very Difficult)

Goglidze vs Bannik, 1954 (44.?)

White to play and win.

Material: Even. White has advanced Ps on the K-side, suggesting a sacrificial P break, to exploit the Black Kb6 and Bf1, and their inability to reach the h8-corner of the board.

Candidates (44.): g5, e5

[44.g5 fxg5 45.h5 gxh5 46.f5 Kf7 stops Pf5]

The standard P break permits the Black Kb6 to stay within the queening square of the f-P.

44.e5 fxe5 [Kf7 45.exf6 wins a P with a winning position]

45.f5 gxf5 [else, 46.fxg6 47.g7 42.g8=Q]

46.g5 hxg5 [else, 47.gxh6 48.h7 49.h8=Q]

47.hxg5 and White queens first, with the mate threat Qb8#.

<whiteshark> is quite correct: after 47.hxg5, White stills wins handily, although not straightforwardly. The variation <CG> gives for is not best play.

47.hxg5 e4 48.g6 Bg2 49.Ke1 d3 50.Ba8

50...d2+ [else nothing stops g8=Q]

51.Kxd2 e3+ 52.Kxe3 Bxa8 53.Kd4 (threatening 54.g7 55.g8=Q)
