|Jun-04-11|| ||HelaNubo: 38. Bh5! is a nice strike from a sorely missed italian master. It could be fit for a tuesday puzzle, maybe.|
|Jun-04-11|| ||sevenseaman: Conviction + courage = a win! Beggi a go-getter.|
|Jul-06-11|| ||CHESSTTCAMPS: I think this is a repeat. White creates a winning passed pawn with 38.Bh5! Time to check.|
|Jul-06-11|| ||rhickma4: I think I might have seen this before.
38.Bh5 forces promotion of the h pawn.
|Jul-06-11|| ||rilkefan: Yesterday's puzzle was harder for me.|
|Jul-06-11|| ||dzechiel: White to move (38?). Material even. "Medium/Easy."|
This one took me longer than it should have. I spent quite a while looking at stuff like
- 38 Bxa6
- 38 Bc4
- 38 e4
etc, etc, trying to set up zugzwang situations. Finally I asked myself, "What advantage, if any, do I have in this position?". That's when I saw the advanced h-pawn and immediately the move
clicked. If black captures the bishop with
and white will get a new queen on h8. If black doesn't capture, say
39 Bxg6 hxg6 40 h7
The more I look at this position, the more I'm thinking that I have seen it (or a position VERY similar to it) before.
Time to check.
|Jul-06-11|| ||johnlspouge: Wednesday (Medium/Easy)
P Beggi vs G Bocchicchio, 1994 (22.?)
White to play and win.
Material: B for N. The White Ph6 is 2 squares away from h8=Q, while the Black K and N (both short-range pieces) are on the other side of the board.
Candidates (38.): Bh5
38.Bh5, with the threat
(A) 39.Bxg6 Nc6 [hxg6 40.h7 wins] 40.Bxh7 Ne8 41.g6-7-8=Q
38...gxh5 39.g6 and a White P queens at h8
Today was much easier than yesterday (if one demands the best winning variation).
|Jul-06-11|| ||estrick: There's only one piec that can be sacrificed, so it must be offered up! |
38. Bh5! creating a baby queen for White, if Black accepts. Otherwise, it's a 'fox in the chicken coup' gobbling up all of the helpless Black pawns in sight.
|Jul-06-11|| ||TheBish: P Beggi vs G Bocchicchio, 1994|
White to play (38.?) "Medium/Easy"
My first instinct was to limit the knight and/or king, but there is no zugzwang here. Then I noticed the pawn breakthrough (which isn't obvious).
38. Bh5!! Nc6
Or 38...gxh5 39. g6 hxg6 40. h7 and the pawn queens.
39. Bxg6 Ne7
This is already resignible, as 39...hxg6 40. h7 is the same as before, and White will queen one way or another.
40. Bxh7 followed by 41. g6, etc.
|Jul-06-11|| ||Phony Benoni: Very familiar to me as well. This may be the one we're all thinking of, from Thursday, January 6, 2011.|

If this is right, don't thank me; thank <patzer2> for his marvelous thematic collections drawn from daily puzzles. A resource well worth studying!
|Jul-06-11|| ||APatzer: Found Bh5.|
|Jul-06-11|| ||M.Hassan: "Medium/Easy" White to play 38.?
Each have 7 pawns and a piece.
38.Bh5 <if...gxh5 39.g6 hxg6 40.g7 and next Queens>
Black seeing the danger is likely to bring the Knight to defend:
Black's Knight lands on a light square that White has the Bishop for and I think it is the time to stretch hand to shake and accept resignation.
|Jul-06-11|| ||LIFE Master AJ: I would say 38.Bh5!
(Black has no defense against BxP/g6. The Bishop is off limits, 38...gh? 39.g6, and White will quickly promote a pawn. If left to his own devices White will play 39.BxP/g6. Once more, Black cannot capture, as 39...hxg6?; 40.h7 etc. White can simply gobble Pawns until Black realizes he is lost and resigns. Black will probably play 38...Resigns.)
|Jul-06-11|| ||Once: There's a hidden office in every city hall. You won't find it listed in the directory in the lobby. Don't bother asking the receptionist - she will deny knowing about it. The office doesn't even have a door. You are supposed to come in via the window, for reasons which are about to become apparent.|
You see, this is the department of superhero registration. And today two black pawns are applying for a permit to wear spandex.
The clerk peers down at them over the top of his half-moon spectacles. "A little short for this kind of work, perhaps?" he asks in his driest of dry municipal tones.
"We might be small, but we are mighty!" squeaks g6. His friend h7 nods vigorously. It's a speech they have been practising for ages.
"We'll see about that," says the clerk, turning his attention to the form on his desk. "Real names?"
"h7 and g6"
"The Pawn Chain Gang."
"And what is your superpower?"
g6 puffs out his little chest as far as it will go, which it has to be said is not very far. "We're invincible."
The clerk looks at them sternly. "Are you sure about that? It's gonna give you problems with the next question."
"Perfectly sure," says h7, the smaller of the two diminuitive would-be crimefighters. "You see, I protect g6 and a white pawn on h6 protects me. Like a shimmering shield of energy. We can't be killed. It's a great superpower. We don't why no-one's tried it before."
The clerk is unconvinced. "Okay, I'll write it down. In.. vin.. civ.. ibil ...ity. Now, what's your fatal flaw?"
"Our what?" they both ask in unison.
"Fatal flaw," repeated the clerk. "Every superhero has one. It's mandatory. Otherwise they're just too boring because they can't lose. Superman has his kryptonite. Spiderman has girlfiend problems. The Terminator has an Austrian accent. John McClane can't find shoes that fit him. Every superhero needs a fatal flaw."
g6 and h7 look confused. "But we haven't got a fatal flaw. We're invincible! We're the pawn chain gang."
The clerk shakes his head sadly and lays his pen down. "I am sorry, fellas. Your application is denied. No fatal flaw, no superhero license. Come back when you've found one."
Thew two pawns are utterly crestfallen. "But what are we gonna do?" they both ask.
"I'll tell you what I'll do," said the clerk. He reaches into his pocket and fishes out a business card, which he hands to them. "Try this guy. He does a lot of superhero work in this town. Talk to him about a fatal flaw. But I warn you ... you might not like what he has to say."
They both look at the business card. And there in shining gold letters is the name "Bishop Sac!"
|Jul-06-11|| ||rilkefan: I have the sense that black entered the endgame without any thought about h6.|
What about 25...gxh5 with the idea of 26.Qxh5 Qd2 and trying for the perpetual?
|Jul-06-11|| ||FSR: 38.Bh5! with the idea of Bxg6! toasts Black. It's funny how oblivious Black (perhaps in time pressure) was - 37...Nb4?? makes it impossible to respond with 38...Ne7! (box).|
|Jul-06-11|| ||Quentinc: <Once>, that may be your best ever. This puzzle feels like a retread (as others have pointed out), but your post more than redeems it!|
|Jul-06-11|| ||Shams: <Once> That's worth something. http://bit.ly/n9Rs5K|
|Jul-06-11|| ||jheiner: P Beggi vs G Bocchicchio, 1994 38. White to play?|
Material: B for N. End game with minor pieces.
White needs to try to break through. The N is more locally mobile than the B since it can switch colors, but can't travel far fast and is presently far from White's most advanced pawns on h6
38...Nc6 39.Bxg6 hxg6 40.h7
And White's P will promote.
|Jul-06-11|| ||scormus: <Once> Brilliant, deserves !!|
|Jul-06-11|| ||GaeBulg: I first looked for some zugzwang positions, but with the knight, I couldn't find a way to set it up. After I looked for a way to break the fortress, and it seems that Bh5 does the trick.|
|Jul-06-11|| ||ossipossi: It is a closed position, so many people think Knight is OK. But BPawns are on same squares as the WBishop, who is faster runner than Knight.|
|Jul-06-11|| ||Morozov: Solving chess puzzles is an odd business. I couldn't figure out yesterday's. Today, I took fewer than five seconds to find it. I hope I would have seen this during live play. Better yet, I hope I would have noticed it as black, before the puzzles starts. Doubt it.|
|Jul-06-11|| ||Morten: Good puzzle and easier than yesterday's.
Did white have anything until black was kind enough to move the knight out of reach of g6? I did not see a white breakthrough, if black just plays 37.-,b5.
|Jul-06-11|| ||fightclub: At first look this seems like one of those endgames that need that one spectacular move that unravels the whole position (which
I'm not too good at). However, on closer look, since all Black's forces are on the kingside, the move Bh5 jumps out:|
a) 38...Nc6 39 Bxg6 Ne7 (39...hxg6 40 h7 and the h pawn queens) 40 Bxh7 b5 41 axb5 Kxb5 42 Bxf5 Nxf5 43 h7 and the h pawn queens
b) 38...gxh5 39 g6 h4 40 gxh7 h3 h8=Q
c) 38...b5 39 axb5 Kxb5 40 Bxg6 Na2+ 41 Kb2 Kb4 42 Bxh7 Nc1 43 Nxb3 Bxf5 44 a5 h7 45 a4 h8=Q
So seems there's nothing that can stop the h pawn from queening
Looks like I didn't see the actual game variation which is probably the best defense. However, this is one rare puzzle where I
can say that I probably certainly would have found the right move OTB as well.
Incidentelly, this 'probably certainly' thing reminds me of the dialogue in my favourite TV show Yes (Prime) Minister:
Sir Humphrey: With Trident we could obliterate the whole of Eastern Europe.
Jim Hacker: I don't want to obliterate the whole of Eastern Europe.
Sir Humphrey: It's a deterrent.
Jim Hacker: It's a bluff. I probably wouldn't use it.
Sir Humphrey: Yes, but they don't know that you probably wouldn't.
Jim Hacker: They probably do.
Sir Humphrey: Yes, they probably know that you probably wouldn't. But they can't certainly know.
Jim Hacker: They probably certainly know that I probably wouldn't.
Sir Humphrey: Yes, but even though they probably certainly know that you probably wouldn't, they can't certainly know that although you probably wouldn't, there is no probability that you certainly would!
