Jul-14-09  gofer: Not sure that this is "Easy". White is bearing down on f7, but black has lots of pieces protecting it so white has to be careful with move order...

20 fxe6 fails even after Bb5 as the rook on a7 is now protecting f7 20 Bxg4 fails as it gives the king an escape square...

But a slight set of forced moves seems to do the trick...

20 f6!

20 ... Bh6 21 fxg7 winning the rook and queen and soon mate

20 ... Bxd2 21 fxg7 winning the rook and queen and soon mate

20 ... gxf6 21 Bxg5 (which cannot be re-taken because of 22 Qxf7#)

20 ... Bc6 21 Bxg5

So the bishop or rook is lost, but that means that black must decide the best defense... ... this is probably 20 ... Bxf6 21 exf6 g6 to make the white pawn protect f7 and create some kind of blockade, but I dont think there is much more available than simply winning the bishop for a pawn!

20 ... Bxf6 21 exf6 g6 22 Bh6 Bc6 23 Bg7 Rg8 24 Qh3 Kd2 25 Qxh7 and white can sac the LSB on g6 to get a passed pawn and open up the king side...

...but this is hardly a clear cut victory... what I have I missed on a Tuesday!!!!

  agb2002: Black's DSB threatens to capture White's but after 20.f6 is lost:

A) 20... Bxd2 21.fxg7 (a double threat 22.Qxf7# and 22.gxh8=Q+) Be3+ (hoping to distract the white queen) 22.Kh1 Rf8 23.gxf8=Q+ Kxf8 24.Qxf7#.

B) 20... h6 (or 20... Bh6) 21.fxg7 + -.

C) 20... g6 21.Bxg5 + -.

D) 20... gxf6 21.Bxg5 + - (21... fxg5 22.Qxf7#).

E) 20... Bxf6 21.exf6 + -.

Jul-14-09  TheaN: Tuesday 14 July


Target: 1:25;000
Taken: 3:21;403 (!)
No par, by far: either this puzzle was a bit too much out of the box, or I'm just sloppy this morning.

Material: =

Candidates: fxe6, Bb5, Bxg5... <[f6]>

A lot of options here, and a few main characteristics. The dark squared Bishops keep each other en prise, Black defended, White undefended. White has a strong f-file and would like to open up on f7, but 20.fxe6 Bxe6 isn't sufficient now that the f7 pawn is defended twice. Furthermore, in combination White would like to interpose the Black Queen's defense. So, we get to:

<20.f6!> there are a few options Black can go at. With certain trouble the Black dark squared Bishop shouldn't capture his opposite adversary.

<20....Bxd2? 21.fxg7 Be3† 22.Kh1 > Black can no longer check, and with the dual threat of Qxf7‡ and gxh8=Q† Black is doomed. To avoid mate Black has to move the other Bishop but this loses a Rook and gains White a new Queen. Similar fates for any dark squared Bishop move aside Bxf6 and Bxf4, but those both lose a full piece. The same also applies to any move that keeps the g7-pawn in, but that also loses the g5-Bishop outright. But on any move besides g6, White should play fxg7.

<20....gxf6 21.Bxg5 > and Black cannot take back due to the mate, and loses a piece in any variation:

<20....Bf4 21.Qxf4 >

<20....Bxf6 21.exf6 gxf6 22.Qxf6 >

<20....g6 21.Bxg5 >

Time to check.

Jul-14-09  zb2cr: Found this. I have nothing to add to the comments by <szechiel>, <Summerfruit>, <TheBish>, <gofer>, <agb2002>, and <TheaN>.
Jul-14-09  Civhai: I think f6 wins a piece. If he does something to save his bishop, fxg7 follows with the threat to mate on f7. So he has to give me a queen on h8.

Jul-14-09  newzild: Yeuillaz's only other game in this database also features a cute, puzzle-like win - but this time he is the giver, rather than receiver:

C Yeuillaz vs P Vezzosi, 1991

Jul-14-09  PinnedPiece: Well, this took me the full two minutes of my self-alloted time (for Tues) and I decided my best move was f-pawn forward. It was either that, or fxe6, and I couldn't see anything positive that way. Now that I have f6 as the answer, I am bothered that it took me so long to see the simple power.

Nevertheless, Personal Result: Success.

Jul-14-09  PinnedPiece: <An Englishman: Good Evening: My candidate for Worst Pun of the Day--"He Yeuillaz Last Laz Best." Anyone think of anything worse?>

Not here. Think you've got it. Full marks.

Jul-14-09  jsheedy: Looked at 20. fxe6, Bxe6, 21. Bb5+, Kf8, and white has no great attack. But 20. f6! cuts off the KB and wins a piece or checkmates: 20...Bxd2?!, 21. fxg7, Rg8 (...Be3+, 22. Kh1), 22. Qxf7#. Or if 20...gxf6, 21. Bxg5, and black can't recapture 21...fxg5, because of 22. Qxf7#. Now to check the actual game...
Jul-14-09  JG27Pyth: <An Englishman: Good Evening: My candidate for Worst Pun of the Day--"He Yeuillaz Last Laz Best." Anyone think of anything worse?>

I realize, Yeuillaz, we all realize that's a terrible pun.

Jul-14-09  Patriot: I'm glad I'm not the only one to think this was not 'easy'. I'm not sure how long I spent on this (knowing it's a puzzle). I doubt I would've seen this OTB and probably would've went with 20.fxe6 Bxf6 21.Bb5+ Kf8. This problem seems strange because I saw the possibility of f6 but mentally I didn't even want to consider it because it seems counter-intuitive. But then I finally saw the main variation:


A) 20...gxf6 21.Bxg5 and black cannot take back due to 21...fxg5 22.Qxf7#

B) 20...Bxd2 21.fxg7 and the double-threat of 22.gxh8/Q+ and 22.Qxf7# is too much to handle.

C) 20...Bxf6 21.exf6 gxf6 22.Qxf6

D) 20...Bh6 21.fxg7 and again the double-threat of 22.gxh8/Q+ and 22.Qxf7# is too much.

Jul-14-09  Utopian2020: Has black ever won playing the French defense?
Jul-14-09  lost in space: well, I first thought that fxe6 is best, but after Be6 there is nothing White can do.

But 20. f6 is winning.

20. f6 Bxd2 (20...gxf6 21. Bxg5; either bishop is gone ore mate after 21...fxg5 22. Qxf7#) 21. fxg7 Be3+ 22. Kh1 and either Qxf7# or the rook is gone.

Jul-14-09  Patriot: <Utopian2020: Has black ever won playing the French defense?>

There are 7,793 games in the chessgames database where black wins in the French.

I'm not a strong player but I've had pretty good results in my club so far.

Jul-14-09  johnlspouge: Tuesday (Easy):

M Boe vs C Yeuillaz, 1991 (20.?)

White to play and win.

Material: Even. The Black Ke8 has 1 legal move and is secured from check. The White Bd2 attacks Bg5, burdening Qd8. White has a battery Rf1 and Qf3 x-raying Pf7 behind the White Pf5. The Black Ra7 is loose. The White Ra1 and Be2 require activation. The White Kg1 is secured from check.

Candidates (20.): f6


(1) 20…Bxd2 21.fxg7 (threatening 22.Qxf7# or 22.gxh8=Q+)

Black must shed an excess of material to avoid mate.

(2) 20…gxf6 21.Bxg5

The White battery pins Pf6 to the mate threat Qxf7#, so after Bxf6, e.g., White is up a B.

(3) 20…Bxf6 21.exf6

White has B for P.

  playground player: <Utopian> I got so tired of playing against the French Defense that I switched to 1.b4 and now I never have to see it anymore. Don't have to bother with the Sicilian, either.

Even when I won against the French, it was only after a long and tedious struggle. Which is not to say I never won as White; but if Black is losing all the time with the French Defense, he's playing it wrong.

Jul-14-09  YouRang: <An Englishman: Good Evening: My candidate for Worst Pun of the Day--"He Yeuillaz Last Laz Best." Anyone think of anything worse?>

Absolutely gawd awful.

Congratulations sir! :-)

Anyway, I eventually found 20.f6 after a long time of trying other stuff, that I won't bore you about.

As for a pun, I'd probably go with:

"Wrapped up nicely with a Boe on top"

Jul-14-09  WhiteRook48: 20 f6 that was just easy!
Jul-14-09  ZUGZWANG67: The Bg5 is protected only by the Q and there' s the possibilty of mate at f7. This calls for 20.f6, when 20. ...Bxd2 is refuted by 21.fxg7 (21. ...Be3+ 22.Kh1). Thus, after 20.f6, the least evil for Black is 20. ...gxf6 21.Bxg5, when White wins a piece for a pawn. Slightly worse for Black is 20. ...Bxf6 21.exf6 gxf6 22. Qxf6, with White gaining a whole piece this time.

Time to check (GULP !).

  kevin86: The key move cuts off the bishop from its defender and threatens the deadly double attack by 20 fxg7!! Black would be threatened with a rook attack (not to mention promotion of the pawn) and mate at f7.

His best possible move would be to abandon the bishop by 20...gxf6 (ironically protecting it) 21 ♗xg5 and the bishop is immune on the penalty of 22♕xf7#

Premium Chessgames Member
  ajk68: It seems the only way for white to go wrong is if 20...Bxd2 21. fxg7 Be3+ 22. Qxe3

22. Kh1!

Jul-14-09  cydmd: As always, <dzechiel> made a clear analysis over the puzzle but I think he missed a quicker mate in his first variation

20.f6 Bxd7 21.Ke7 Qxf7#

Jul-14-09  Everett: f6

Interference, pressure on f7, misplaced rook on h8.
