<12....?>
Target: 0:40;000
Taken: 0:21;651
Par
Material: = (no captures)
Candidates: 12.Bh6.... oh damn wrong color... (12....)<[Bxh3]> -ML-
As you may notice I thought it was White to play at first, making up for at least ten of my valuable 40 seconds I have on Monday >_>. Once I noticed Black to play, I immediately spotted: <12....Bxh3> which is not at all an illogical move even if it doesn't win on the spot. Only now, White probably noticed he cannot capture on h3: /A\
<13.Bxh3 Nf3†  > as the Bishop is defending against the Knight fork. As such, White has to stop the fork first, and the only way to do so and not to end up a full piece down immediately is: /B\
<13.Bxd4> If Black takes on d4 (13....cxd4?? 14.Bxh3  ) White is even a tad bit better. However, Black wins due to a double capture of the h3-Bishop, now going to g2. <13....Bxg2> now White is down a piece again and there is no zwischenzug this time. On 14.Bxe5 (14.Bxc5 without variation), 14....Bxf1 15.Bxg7 Kxg7 . and: <14.Kxg2 cxd4 >
Time to check. |

| Jun-08-09 | | johnlspouge: Monday (Very Easy):
C Pilnick vs Seidman, 1954 (12...?) Black to play and win.
Material: Even. The White Bg2 is overburdened, protecting Nh3 and f3 against the royal fork Nd4-f3+. The Black Kg8 is secured against all checks. Candidates (12…): Bxh3
12…Bxh3
(1) 13.Bxd4 13…Bxg2
The double threat 14…cxd4 and 14…Bxf8 wins a piece.
(2) 13.Bxh3 [else, drop a piece] Nf3+
Black wins Q for N. |

| Jun-08-09 | | TheaN: 1/1
<goslar, zb2cr>: I think <sfm> was meant to be sarcastic with that post... and it was pretty funny at that. |
|
| Jun-08-09 | | randomsac: Free knight! Or if you are lucky, you can get a queen at discount price (because of a knight fork). Please come again. |
|
| Jun-08-09 | | sfm: <zb2cr: after the given line, White is down by a Rook vs. a Pawn, but I guess no-one would be so ungentlemanly as to mention that to him, perhaps?>
We could hope that! It's bad enough for your prospects to have a lost position - to realize it makes it directly painful! |
|
| Jun-08-09 | | Patriot: I got the right move 12...Bxh3 and saw the knight fork on f3, but fell into the "This must be it because it's an easy Monday" trap and didn't properly analyze further. 13.Bxd4 must be calculated (or at least noticed) to try to recover material but simple counting shows it fails as others have pointed out: 13...Bxg2 14.Bxe5 Bxf1 15.Bxg7 Kxg7 16.Kxf1 and black wins a rook for a pawn. I certainly didn't consider 13.f4, but what's the point? Black was correct in playing the simple 13...Bxg2. |
|
| Jun-08-09 | | MaxxLange: this idea comes up a lot in Closed Sicilian (or FORMATION: KING'S INDIAN ATTACK, if you must call it that) games and can be played to trade the light-squared bishop even if there is nothing on h3 to take. |
|
| Jun-08-09 | | JG27Pyth: <Fezzik: Just as an exercise, I wonder how many people set up the position against a strong computer and were able to defeat it after winning the piece.> I just did (I like to play out won games against the computer for technique), played it out against Fritz... I'm not a titled player and it was pretty dang easy. There are "won" games that are hard to convert against a good player... but this position has very little for White to work with...I found no difficulty in preventing counterplay and just exchanging down down down to a won ending... |
|
| Jun-08-09 | | jheiner: <sleepyirv: Bishop is guarding two sqaures, so the bishop isn't guarding any squares.> Clever. I like that.
This one took me forever to try and find the right move for White. There was just nothing forcing. Then I realized the puzzle was for Black. Hehe. Saw it immediately. |
|
| Jun-08-09 | | YouRang: Quite easy, as it should be on Monday.
We steal a knight in broad daylight with 12...Bxh3 because the bishop that was guarding the knight is overworked (it's also guarding against the K+Q knight fork: Nf3+). |
|
| Jun-08-09 | | kevin86: I answered this in a New York second...white's bishop is overworked. It is forced to defend both the knight at h3 and prevent the adverse fork at f3. Black wins a piece-and with it the game. |
|
| Jun-08-09 | | Kasputin: Black plays 12 ...Bxh3 and wins a piece because white's g2 bishop needs to stay and guard f3 against a k and q fork. White can remove the offending knight with 13. Bxd4 but after ...Bxg2 white still comes out a piece down. |
|
| Jun-08-09 | | lzromeu: I do it. Its mean that's Knight fork week?
King's Indian needs kf3! Someone agree? The white oppening had mistakes a lot. |

 | | GoldenKnight: <<chillowack>: What I wonder is: how does Pilnick have a 2126 rating in 1954, when the rating system didn't even exist until the 60s or 70s?> When I started playing in the early '60s the USCF had its own rating system, and may have had it back in 1954. It was in the mid-'60s that hired Professor Arpad Elo to revamp the system and put it on a solid mathematical footing. I myself gained five points when that happened. Later he became the ratings statistician for FIDE and now the rating points are called Elo in his honor (which I didn't find out until I came back into chess in the '90s). Then after that, he began rating past players (Lasker, Capablanca, etc.), so that's how that may have happened with Pilnick also. |
|
| Jun-08-09 | | YouRang: <sleepyirv: Bishop is guarding two sqaures, so the bishop isn't guarding any squares. > Technically, I think it would be more accurate to say "Bishop is guarding two squares, so the bishop is guarding one square". But I suppose the statement then loses some of it's poetic value. :-\ |

 | | gawain: Of course ...Bxh3 and the bishop cannot be taken because of the knight fork that follows. Simple and pleasing. |
|
| Jun-08-09 | | SamAtoms1980: 12 ... Bxh3 and that knight is on the way to the dog food factory. 13 Bxh3 hangs a royal fork. Got light squares? |
|
| Jun-08-09 | | Sabinas: Ahh, finally one I got right quick, Bxh3. It is odd that this was a game between GM's. I guess everyone makes mistakes. |
|
| Jun-08-09 | | WhiteRook48: ah, totally lost it! Becoming a patzer again! |
|
| Jun-08-09 | | falso contacto: I dig a pilnick. |
|
| Jun-08-09 | | stevenmeow: are you sure that they were GM's?
the one listed has a 2126 rating |
|
| Jun-08-09 | | xrt999: black moved and then resigned out of turn? From what I am told that is not polite, right up there with playing on in a lost position. |

| | penarol: G Barcza vs Tal, 1971 is similar |

|
| Jul-18-13 | | jerseybob: 11.c3 for better or worse. The knight must be challenged! |
