|May-01-10|| ||Shah Mat: i peeked at the answer by accident.
next time i'll experiment on Fritz 12 / Rybka, but at least i got the first move =P
|May-01-10|| ||Phony Benoni: Easy enough. White just pushes a pawn.|
|May-01-10|| ||RandomVisitor: 44.Bf7 might also win.

Beautiful. 47. h5 caps the solution. Pity Goglidze missed it OTB.
|May-01-10|| ||twinlark: True <RV>, but pushing 4 pawns in a row to the fifth rank in four successive moves has a unique elegance about it.|
|May-01-10|| ||Quentinc: I thought it was 44. g5 fxg5 and then 45. h5. Too complicated for my limited powers of visualization!|
|May-01-10|| ||dzechiel: White to move (44?). Material even. "Very Difficult."|
OK, this one makes up for the "gimmes" earlier in the week.
I guessed wrong with
same as was played in the game, except I had the line going
44...fxg5 45 h5 gxh5 46 f5 Bb5 47 f6 Be8 48 f7 Bxf7 49 Bxf7
with a tough win for white (which may or may not be the case).
Time to read the kibitzing and see who's really on their game.
|May-01-10|| ||wenx: 44.e5 fe5 45.g5 followed by f5 should win|
|May-01-10|| ||OBIT: Just on positional considerations, my move would have been 44. g5, fixing the Black g-pawn on the same color as the bishop so that it can be picked off later. I see the move recommended in the notes is 44. e5. |
Playing out the game continuation, I think I'd have played 49. Bf7 instead of 49. Bh7. I'm guessing this is followed by 49...Kd6 50. g6 Ke7 51. e5 Kf8 (else Ba2 followed by g7). Hmm, maybe this is also drawn. I'll have to look at this ending tomorrow.
|May-01-10|| ||sh8911: beautiful£° but I miss it...... the correct plan is past h pawn|
|May-01-10|| ||Leibnoob: Fritz says bf7|
|May-01-10|| ||An Englishman: Good Evening: It was easy, but amazing; it looks like a composed problem, and yet this occurred in a real game.|
|May-01-10|| ||lostgalaxy: I got the serial suicide idea but it turns out it takes a bit of manouvre to defend Black's connected pawns.|
|May-01-10|| ||al wazir: I found the solution, i.e., the sequence of sacs that <lostgalaxy> felicitously dubs "serial suicide" -- but I had serious misgivings about what happens if black defends with his , e.g., 44. e5 Kc7 45. exf6 Kd8 46. f7 Ke7.|
|May-01-10|| ||tratra: tratra: White to play
Goglidze vs Bannik
44. g5 hxg5 (44...fxg5? 45. fxg5 hxg5 46. hxg5 Kb5 47. Bf7 Kxb4 48. Bxg6 ) 45. f5 gxf5 (45...gxh4 46. fxg6 h3 47. g7 h2 48. g8Q h1Q 49. Qb8#) 46. h5 and white queens first with initiative
time to check
|May-01-10|| ||tratra: 44.e5! fxe5 45.f5!! gxf5 46. g5!! hxg5 47.h5!! very nice 3 pawns sac for a single passed pawn!|
|May-01-10|| ||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
|May-01-10|| ||scormus: Nice p-breakthrough study! There seem to be several ways for W to win (or not win) and I could see I was in danger of wasting another Saturday. So I cannot take much credit as I chickened out of posting my "solution" starting 44 g5 and the 45 f5 or h5 depending on whether B plays 44 ... fxg5 or hxg5. on reflection I think either would win if B played fxg5. The WB control of the long W diagonal makes the task easier. |
My mind in more on Anand-Topalov just now - I find it very humbling to see the tremendous quality of play.
|May-01-10|| ||steventyp: i did see that e5 as the 1st candidate move, but when i saw the game continuation, it left me wondering why g5 doesn't win as well? after 44...fxg5 45. h5 gxh5 46. f5 Kc7 47. e5 h5 48. Bb5 etc. might be less tidy, but perhaps workable as well?|
|May-01-10|| ||TheBish: Boy, do I have egg on my face! I gave a long analysis of how 44. g5(!) "works", not accounting for how quickly Black's king can come to the rescue. Worse yet, I think I have seen this endgame or at least similar ones, and am usually good at these breakthrough themes. That'll teach me to solve Saturday problems while drinking red wine! (Previous post deleted from embarassment and to save space!) :-)|
I'll just repeat my initial impressions from my first post, and an explanation of what led me down the wrong path (maybe similar to the player's thoughts):
[My first impression was wow, what a beautiful arrangement of pawns and pieces! Looks like a composed endgame problem. All the pawns on the same rows, and even the kings and enemy bishops have a symmetrical arrangement.
My second thought was that this had to be a pawn breakthrough. What else? Suddenly, the problem got easier. Probably the best well-known pawn breakthrough is the first one I learned, with White pawns on f5, g5 and h5, and Black pawns on f7, g7 and h7, with the winning move for White being 1. g6!. In this case, the pawns are back one rank with bishops on, making things more interesting, but with the same winning idea.
Now whichever pawn captures, the opposite White pawn advances to effect the breakthrough, i.e. if 44...hxg5 45. f5!, or 44...fxg5 45. h5!]
As I said, this is bogus, so analysis deleted! Now I have to make up for this miss with a strong finish on Sunday.
|May-01-10|| ||whiteshark: Got the three pawn sacrifices. The rest are just minor details.|
|May-01-10|| ||TheBish: Also winning is 44. e5! fxe5 45. g5 (instead of 45. f5) hxg5 45. f5! gxf5 45. h5, transposing to the winning line given in the note. However, the line given is more aesthetically pleasing!|
|May-01-10|| ||gofer: we have discussed this before...
The pawn formation below is a clear "win" for the more advanced row of pawns.
click for larger view
a) Advance the centre pawn, it must be taken
b) Advance the outside pawn, whichever is not on the open file created by the pawn that has just been taken
c) Now one of the pawns will be taken and the other will promote!
1 g6 hxg6 2 f6 winning
1 g6 fxg6 2 h6 winning
In the game we have today both pawns will promote on the same move, neither with check.
44 g5 hxg5 45 f5 gxf5 46 h5 g4 47 h6 g3 48 h7 g2 49 h8=Q g1=Q
44 g5 fxg5 45 h5 gxh5 46 f5 g4 47 f6 g3 48 f7 g2 49 f8=Q g1=Q
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! So to avoid mate black has to allow the promotion, avoid
mate and then try to promote its g pawm - which is not going to be possible!
An instructive puzzle for those that didn't known this previously, but if you do know this then it was "Easy! Not "Very Difficult". So the answer is...
44 g5 winning
Time to check...
|May-01-10|| ||Daviddavidson: First Post!
g5 looked good, but I like 44.f5 gxf5 45.exf5 Kc7 46. g5 [pawn exchanges continue until either the f file or g file are cleared]. If black pawn slips by, it cant harass the king and will be on g file, promoting on bishop proof g1. The black king wont be able to catch up with the pawns either. f8 and h8, where Wpawns would promote, are black and biship-proof. This seemed the most sound strategy to me. I cant understand how in the real match white moved 45. fxg5 ???
|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!
