Nov-02-08  Ladolcevita: i've found the starting moves,but i think the latter moves are harder

  al wazir: <MostlyAverageJoe: 40...Rd2 ? After 41. Qh8+ Bg8 42.Nxe6+.>

Followed by 42...Ke7 43. Nf4, I suppose, defending g2 and threatening 44. Qf6#. Very nice. Thanks.

I see I was even farther than I thought from getting this one -- but so was everyone else.

43. Qf6#

Nov-02-08  stacase: I got the first several moves, but not all the way to the end.

Over the board I might have tried the Rook sacrifice, but pulling the rest of it off would be real doubtful. That's why I'm only 1400, I'll try stuff like that without seeing it all the way to completion. In other words, going on a hunch. Pays off sometimes (-:

  Once: I can see a firm path leading into a swamp...

Our pride and joy is the Rc8, which owns the black back rank. And black has one of the ugliest bishops possible at f7. If only our rook wasn't attacked, we could play Qxh6 and Ng5 and it would be a frabjous day, callou, callay.

So unless we can whip up some deadly queen action (37. Qxh6 Qxc8 38. Ng5? nope) we have to do something with our attacked rook. Retreating looks wussy (and would not be a puzzle). So all we are left with is 37. Rxf8 Kxf8 38. Qxh6+.

Now what? 37. ... Ke7 looks messy, with black walking into a bishop and queen crossfire. But what to do on 37...Kg8? Has white really got enough firepower to winkle out the black king. After a few minutes I gave up and allowed Fritz a chance to play. And this is what he came up with (not necessarily the optimum line):

37. Rxf8+ Kxf8 38. Qxh6+ Kg8 39. Ng5 Qe7 40. Bb5 Be8 41. Ne4 Qg7 42. Nf6+ Kf8 43. Qxg7+ Kxg7 44. Nxe8+ Kf8 45. Nf6 Rc1

After the dust has settled, white wins the exchange and a pawn. And the certain knowledge that I would never have spotted all that from the starting position.

Nov-02-08  Samagonka: Not that insane for a Sunday puzzle. Easily got started but left off mid-way...
Nov-02-08  james biwi: wat about 39. Qh8 circling the king! threat. 40.Qf6+Kf8 41.Ng5! and 42. Nh7+
Nov-02-08  MrSir: the puzzle is why did black resign. i see a draw here.
Nov-02-08  znprdx: Well like most people today the Rx[B]f8 idea jumps out as being pretty straightforward - but it seemed rather underwhelming at first so I started looking at an immediate Be8 - nice to see that when it is finally played the point is made: a very pretty self-smothering mate.....

<Once:Now what? 38. ... Ke7 looks messy......> But what to do on 38...Kg8? Thanx for this post - I don't feel so bad about coming up short.

37. Rx[B]f8+ Kx[R]f8 38. Qx♙h6+ Kg8 39. Ng5 Qe7 40. Bb5 Be8 41. Ne4 Qg7 42. Nf6+ Kf8 43. Qx[Q]g7+ Kx[Q]7 44. Nx[B]e8+ Kf8 45. Nf6 Rc1

I long for the day the Chessworld returns to showing piece captures - if for no other reason than to assist the development of one's visualization (or blindfold skills). Pieces do not capture squares - our current conventions are inconsistent.

Nov-02-08  Alphastar: Saw the first four moves, then decided I could calculate the rest from there. Nice flashing attack by Piket.

By the way, if anyone is interested, the games I played in a tournament in august finally arrived in the database - Game Collection: open dutch youth championships 2008: Alphastar if you want to take a look. It includes a win over a 2300.

Nov-02-08  njchess: MrSir, Black resigns because if 44. ... Bxf7 45. Qh4#, or if 44. ... Qxf7 45. Bxf7 and White has a winning game, or if 44. ... Kh7 45. Qh4+ Qh5 46. Qxh5#. Great light square vs. dark square endgame.
Nov-02-08  Eurotrash: In a live game, I'm pretty sure I'd play 37.Rxf8+ on intuition alone. It just looks like the right move. I consider myself to have solved this puzzle, even without seeing every possible line.
Nov-02-08  karnak64: Neat puzzle. What are the "Antwerp Lost Boys"? Anything to do with my son's boy scout troop?
Nov-02-08  PinnedPiece: As far as I'm concerned I figure I DID NOT solve the puzzle because in my lines, I never tried 39.Qh4, which is the winning move in my opinion. (The first three are not enough, I don't believe...if 39 Qg5 or 39 Ng5, the attack fizzles.)

If you don't see that Queen move, then I think you end up with a draw.

  al wazir: <MAJ: 43. Qf6#> Of course. Thanks.

  agb2002: The black castle is weak and the queen and rook may hang. The only move I see is 37.Rxf8+ Kxf8 38.Qxh6+:

A) 38... Kg8 39.Ng5

A.1) 39... Rd2 (threatening ... Qxg2 mate) 40.Qh7+ Kf8 41.Nxe6+ Ke7 42.Qh4+ Kxe6 43.Qf6+ Kd5 44.Qf3+ winning the queen.

A.2) 39... Qe7 (preventing Qf6 eventually) 40.Bd7 (Q)Rxd7 41.Ne4 followed by 42.Nf6+.

B) 38... Ke7 39.Qg7

B.1) 39... Kd8 (unpinning the bishop) 40.Qf8+ winning the bishop.

B.2) 39... Qe4 (threatening ... Qf4+) 40.Qf6+ Kf8 41.Ng5 Qb7 42.Nxe6+ Kg8 43.Qg7 mate.

B.3) 39... Rf1 (defending along f) 40.Nd4 Rc1 41.Qf6+ Kf8 42.Qh8+ Ke7 (42... Bg8 43.Qh6+) 43.Qh4+ Kf8 44.Qh6+ winning the rook.

Time to post and check.

Premium Chessgames Member
  agb2002: Now I see that my line B.3) loses against 40... Qe4 (instead of Rc1) 41.Nc6+ Kd7. I should have pursued the most forcing move 39.Qh4+, so stepping into the same stone again.
Nov-02-08  SufferingBruin: Rxf8+ Kxf8
Qxh6+ Ke7
Qg5+ and draw by repetition.

I just drew against Novikov. Not bad.:)

Seriously, I'm not getting this one.

UPDATE: And why? Because I always move forward, forward! I have to check on Qg5 instead of looking at the long range possibility Qh4 which would've led to Ng5... I mean, I never even considered Qh4. I'm going for a walk.

  johnlspouge: Sunday (Insane)

Piket vs I Novikov, 1996 (37.?)

White to play and win.

Material: N for B. The Black Kh8 has 3 legal moves. The Black K-side has weak dark squares, accentuated by Pe5 and Qh4, The Rc8 also pins the dark-square Bf8 to Kg8. The White Bh4 and Nf3 require activation.

Candidates (37.): Rxf8+

For an exchange, White picks up a P and puts the Black Kg8 in a net.

37.Rxf8+ Kxf8 38.Qxh6+

Again, I have insufficient time, but Pe5 coupled with the Ba4 permits White to put Qh6 either at f6 or g5 to prevent Kg8 from escaping through e7. White can also play Nf3-g5. The first move 37.Rxf8+ is obvious, but the analysis I give only makes it “playable” as a puzzle.

Nov-02-08  TheaN: 6.5/7

In correlation with <37.Rxf8† Kxf8 38.Qxh6†> I noticed the pattern with both Kg8 and Ke7 but could not see the entire pattern. Would've left it off the board in a real game. I'm giving myself half a point. *cracks fingers* Monday, here I come.

Nov-02-08  Woody Wood Pusher: Well I found the forced draw like everyone else, but with the queen on g5 in my lines its no wonder I missed Qh4 and Ng5 together!
Nov-02-08  SufferingBruin: Shake hands with a brother, Woody, shake hands with a brother.
Nov-03-08  sallom89: well played!
Premium Chessgames Member
  kevin86: A surprising exchange sac sets this one to a quick finish.
Nov-04-08  patzer2: For the Sunday Nov 2, 2008 puzzle solution, White initiates a winning pursuit (King Hunt) combination with the sham exchange sacrifice 37. Rxf8+!
