Jun-16-10  eblunt: Like <dzechiel> I had the Qb6 route, but went 36 ... ♕b6 37 ♘a3 ♗d4 which white doesn't really have any good answer to. Not as good as other solutions, but I'd certainly fancy my chances OTB from black's position.
Jun-16-10  Dr. J: Solution 1 (game): 36 ... Ng3, when White's best play is to concede the exchange; or

Solution 2 (various commentators, inc. me): 36 ... Qb6, and, after 37 Na3 or Nc3 or Qe2, winning the exchange by ... Nb6.

As far as I can tell, these solutions are equally good.

Jun-16-10  Dr. J: <whiteshark: I was not completely awaken when I tried it... (fm: whiteshark's collected excuses)>

Remember: "The most important thing in life is to have your excuses in order."

Jun-16-10  zanshin: I (pretty much) got it - up to <40.Ke2>, so I will consider this one 'solved'.
Jun-16-10  Patriot: I thought this was difficult for a Wednesday. I didn't see the point of 36...Rxc1 and so looked at a few threatening moves: Ng3 and Qb6.

What I didn't like about Qb6 is this line: 36...Qb6 37.Nc3 Ng3 38.Be3. But after looking at this more, black could simply play 37...Bxc3 38.bxc3 b2 so my line was not best.

I thought 36...Ng3 looked ok because after 37.fxg3 Qxf1+ 38.Qxf1 Rxf1+ 39.Kxf1 Rxc1+ 40.Ke2 black looks better. I didn't get far enough to see that 40...Bxb2 polishes things off.

I also looked at the sideline, 36...Ng3 37.fxg3 Qb6+, but thought this was pretty pointless compared to the main line. It carries some logic in that it trades material when ahead, cripples the kingside pawns, and creates connected passed pawns in the center. A major downfall to this, compared to the main line, is that it leaves more material on the board including the queens.

  chrisowen: Knight strikes get the ball rolling Ng3 pins the rook. Gutter that one pawn loading back rank. Leg it down bowling in series fxg3 qxf1+ qxf1 rxf1+ Kxf1 Rxc1+ the big skid traps the bishop exposing clear water eyes Ra1. The dude is looking out back door ratifying Ra8 scurries away but Bb1 is dead meat. Black parts a piece up great chop shop.

  kevin86: Silly me! I was looking for a mate and not a vacuum attack of white's queenside.

Black will take the bishop and win easily-so white struck his colors.

Jun-16-10  David2009: J B Bednarski vs Podgaets, 1972 Black 36...? Black is a Pawn up. Candidates are 36...Qb6 and 36...Ng3. (A) 36...Qb6 37 Nc3 Ng3 38 Nxd5 Rxc1 39 Nxb6 Rxd1 40 Rxd1 Bd4 41 Rxd4 Ne2+ 42 Kf1 Nxd4 and Black is still a Pawn up but White is over the worst;
(B) 36...Ng3 37 fxg3 Qb6+ 38 Kh2 Qxb5 39 Rxf8 Rxf8, when Black has a clear advantage: White's Bb1 remains out of play and Black's central passed Pawns are very threatening.
In the game I would prefer B. Time to check:
====
I found the first move but missed the best follow-up. Chess blindness!
Jun-16-10  JG27Pyth: I always learn something... today I learned I can't count.
Jun-16-10  MiCrooks: As usual the only problem was thinking there might be something better. Ng3 leads to the win of another pawn AND a piece (missed by many of the commenters). After Rxb1 Black is a piece and two pawns up, and has a strong passed pawn. White could have resigned anytime during the forcing variation. Guessing time control was at 40 so wanted to get there first...typically the case when you get player moving THEN resigning.
Jun-16-10  zooter: I was looking at 36...Ne3 (forking the queen and rook) for a long time, but Bxe3 and there seems to be no way to continue the attack.

Then I realized that 36...Ng3 offers hope. 37.fxg3 Qxf1+ 38.Qxf1 (forced) Rxf1+ 39.Kxf1 Rxc1+ 40.K-moves Bxb2 wins for black

What if black refuses the sacrifice by 37.Re1?

Then 37...Qxf2+ 38.Kh2 Be5+ leads to mate

Best seems to lose the exchange though black has an overwhelming advantage. Time to check and I'm sure the regulars have analyzed this thoroughly

  benveniste: I would have played ♕b6 over the board, because I could see how either 37. ♘c3 or 37. ♕xb3 gains a piece. I have no idea which a computer would prefer.
Jun-16-10  M.Hassan: "medium/easy" category, Black to play.
Black is a pawn up

The first thing that came to my mind, is the occupation of a file by black 36...... Ra8
37.Rxa8 Rxa8
38.Qxb3 Rb8
39.Qa4 Qc6
40.Rd1 Qxb5 and black will be up further by a Knight OR
36........Ra8
37.Na3 Rxa3
38.bxa3 Qxa1
39.Qxb3 and again black will be up by a Knight. Time to check Completely wrong!!

Jun-16-10  mastyin: 1. ..Ng3+ 2. Kg7 Nxf1 3. e3
1. ..Ng3+ 2. fxg3 Qxf1 3. Qxf1 Rxf1 4. Kxf1 Rxc1 4.Ke2 Bxg2

Not sure if there is a better solution.

Jun-16-10  guybrush: A couple of suggestions of 36...Qb6?! Doesn't 37 Qxb3 let white hang around for a bit? 37...Ng3 is no longer an option, due to 38 Qxg3 with material equality. Perhaps I'm missing something obvious. In any case, white's overall position is still horrible, as was the rest of his play upto the 36th move.
Jun-16-10  Ferro: 9 Nb1??

9 NxCarlsen!!

Jun-16-10  Ferro: 9 Nxb5 (carlsen!)

Does anyone have any questions? :-)

Jun-16-10  David2009: A postscript to J B Bednarski vs Podgaets, 1972: 36...Qb6 also seems to win comfortably as suggested by <dzechiel> and <benveniste>:

since 37 Nc3 and 37 Qxb3 each lose a piece, to 37...Bxc3! and 37...Nd6! respectively. CraftyEGT link to check other White defences: http://www.chessvideos.tv/endgame-t... (Bednarski-Podnaerts 1972 36...Qb6 variation). Crafty refutes <eblunt>'s defensive idea 37.Na3 with 37...Ng3! 38.Be3 Qxe3 39.fxe3 Rxf1+ 40.Qxf1 Nxf1 41.Kxf1 Rc1+ 42.Ke2 Bxb2

which has echoes of the game finish.

  YouRang: I saw a number of tactical possibilities (opening f file for Q+R battery; R on open c-file, diagonal attack on b2), but I didn't see right away how to make any work.

In fact, I looked at 36...Ng3 two or three times before I took it deep enough to recover the piece, and satisfy myself that it had to be the solution.

So, considering the position after the forced line 36...Ng3 37.fxg3 (37.Re12 Qxf2+ 38.Kh2 Be5 looks like death for white) 37...Qxf1+ 38.Qxf1 Rxf1+ 39.Kxf1 Rxc1+ (recovering the piece), the black K must move (e.g. 40.Ke2), and then I have 40...Bxb2! attacking the defender of Bb1, and thus I win another piece.

In the end, I see that this line brought all of those tactical possibilities together quite nicely.

BTW, the given position looks horrible for white after 36 moves. All pieces except one on the back rank (reminding me of a certain game between Kasparov and Karpov).

  johnlspouge: Wednesday (Medium/Easy)

J B Bednarski vs Podgaets, 1972 (36...?)

Black to play and win.

Material: Up a P. The White Kg1 has 2 legal moves. Black has a battery Bg7 and Qf6 on the a1-h8 diagonal and another battery Rf8 and Qf6 on the f-file behind Nf5, suggesting a discovered attack on the weak Pf2 with Nf5. The Black Rc8 burdens Qd1 with the protection of Bc1. The White Nb5 is loose. White threatens Qxg3, regaining the P. The Black Kh8 is secured from check.

Candidates (36...): Qb6, Rxc1, Ng3

[36Qb6 37.Qxb3 holds everything together]

[36...Rxc1 37.Qxc1 goes nowhere]

36Ng3 37.fxg3 [R moves Qxf2+ wins another P] [else, Nxf1]

37Qxf1+ 38.Qxf1 Rxf1+ 39.Kxf1 Rxc1+ 40.K moves Bxb2

Black wins Ra1 or Bb1 gratis on the next move, leaving him up at least 2B+2P for N.

  chrisowen: <Patriot does anyone.. have any questions?> A for oh airy awn. Ears to the ground, hog a coffee a slender layback on the payback? A tribe called upon desserts the scenario good call. I came late it was tough that I flip-flopped across. We need well knocking up every now and then just dont ring my neck if I gum up the works ;) Perchance tomorrow's specialty is the monkey's deferred bum?
Jun-16-10  reti: I agree with YouRang. This position is full of tactical possibilities.
Jun-16-10  RandomVisitor: The only move better than 36...Ng3! is 35...Ng3!.
Jun-17-10  turbo231: missed it
